Warning: Estimators are not recommended for new code. Estimators run v1.Session-style code which is more difficult to write correctly, and can behave unexpectedly, especially when combined with TF 2 code. Estimators do fall under our compatibility guarantees, but will receive no fixes other than security vulnerabilities. See the migration guide for details.

This Colab-based tutorial will interactively walk through each built-in component of TensorFlow Extended (TFX).

It covers every step in an end-to-end machine learning pipeline, from data ingestion to pushing a model to serving.

When you're done, the contents of this notebook can be automatically exported as TFX pipeline source code, which you can orchestrate with Apache Airflow and Apache Beam.

Background

This notebook demonstrates how to use TFX in a Jupyter/Colab environment. Here, we walk through the Chicago Taxi example in an interactive notebook.

Working in an interactive notebook is a useful way to become familiar with the structure of a TFX pipeline. It's also useful when doing development of your own pipelines as a lightweight development environment, but you should be aware that there are differences in the way interactive notebooks are orchestrated, and how they access metadata artifacts.

Orchestration

In a production deployment of TFX, you will use an orchestrator such as Apache Airflow, Kubeflow Pipelines, or Apache Beam to orchestrate a pre-defined pipeline graph of TFX components. In an interactive notebook, the notebook itself is the orchestrator, running each TFX component as you execute the notebook cells.

Metadata

In a production deployment of TFX, you will access metadata through the ML Metadata (MLMD) API. MLMD stores metadata properties in a database such as MySQL or SQLite, and stores the metadata payloads in a persistent store such as on your filesystem. In an interactive notebook, both properties and payloads are stored in an ephemeral SQLite database in the /tmp directory on the Jupyter notebook or Colab server.

Setup

First, we install and import the necessary packages, set up paths, and download data.

Upgrade Pip

To avoid upgrading Pip in a system when running locally, check to make sure that we're running in Colab. Local systems can of course be upgraded separately.

try:
  import colab
  !pip install --upgrade pip
except:
  pass

Install TFX

pip install tfx

Uninstall shapely

TODO(b/263441833) This is a temporal solution to avoid an ImportError. Ultimately, it should be handled by supporting a recent version of Bigquery, instead of uninstalling other extra dependencies.

pip uninstall shapely -y

Did you restart the runtime?

If you are using Google Colab, the first time that you run the cell above, you must restart the runtime (Runtime > Restart runtime ...). This is because of the way that Colab loads packages.

Import packages

We import necessary packages, including standard TFX component classes.

Set up pipeline paths

# This is the root directory for your TFX pip package installation.
_tfx_root = tfx.__path__[0]

# This is the directory containing the TFX Chicago Taxi Pipeline example.
_taxi_root = os.path.join(_tfx_root, 'examples/chicago_taxi_pipeline')

# This is the path where your model will be pushed for serving.
_serving_model_dir = os.path.join(
    tempfile.mkdtemp(), 'serving_model/taxi_simple')

# Set up logging.
absl.logging.set_verbosity(absl.logging.INFO)

Download example data

We download the example dataset for use in our TFX pipeline.

The dataset we're using is the Taxi Trips dataset released by the City of Chicago. The columns in this dataset are:

pickup_community_area	fare	trip_start_month
trip_start_hour	trip_start_day	trip_start_timestamp
pickup_latitude	pickup_longitude	dropoff_latitude
dropoff_longitude	trip_miles	pickup_census_tract
dropoff_census_tract	payment_type	company
trip_seconds	dropoff_community_area	tips

With this dataset, we will build a model that predicts the tips of a trip.

_data_root = tempfile.mkdtemp(prefix='tfx-data')
DATA_PATH = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/chicago_taxi_pipeline/data/simple/data.csv'
_data_filepath = os.path.join(_data_root, "data.csv")
urllib.request.urlretrieve(DATA_PATH, _data_filepath)

('/tmpfs/tmp/tfx-data1p69mnqt/data.csv',
 <http.client.HTTPMessage at 0x7f1f00348df0>)

Take a quick look at the CSV file.

Create the InteractiveContext

Last, we create an InteractiveContext, which will allow us to run TFX components interactively in this notebook.

# Here, we create an InteractiveContext using default parameters. This will
# use a temporary directory with an ephemeral ML Metadata database instance.
# To use your own pipeline root or database, the optional properties
# `pipeline_root` and `metadata_connection_config` may be passed to
# InteractiveContext. Calls to InteractiveContext are no-ops outside of the
# notebook.
context = InteractiveContext()

WARNING:absl:InteractiveContext pipeline_root argument not provided: using temporary directory /tmpfs/tmp/tfx-interactive-2022-12-29T10_09_52.009692-w3s4ta1b as root for pipeline outputs.
WARNING:absl:InteractiveContext metadata_connection_config not provided: using SQLite ML Metadata database at /tmpfs/tmp/tfx-interactive-2022-12-29T10_09_52.009692-w3s4ta1b/metadata.sqlite.

Run TFX components interactively

In the cells that follow, we create TFX components one-by-one, run each of them, and visualize their output artifacts.

ExampleGen

The ExampleGen component is usually at the start of a TFX pipeline. It will:

Split data into training and evaluation sets (by default, 2/3 training + 1/3 eval)
Convert data into the tf.Example format (learn more here)
Copy data into the _tfx_root directory for other components to access

ExampleGen takes as input the path to your data source. In our case, this is the _data_root path that contains the downloaded CSV.

example_gen = tfx.components.CsvExampleGen(input_base=_data_root)
context.run(example_gen)

Let's examine the output artifacts of ExampleGen. This component produces two artifacts, training examples and evaluation examples:

artifact = example_gen.outputs['examples'].get()[0]
print(artifact.split_names, artifact.uri)

["train", "eval"] /tmpfs/tmp/tfx-interactive-2022-12-29T10_09_52.009692-w3s4ta1b/CsvExampleGen/examples/1

We can also take a look at the first three training examples:

# Get the URI of the output artifact representing the training examples, which is a directory
train_uri = os.path.join(example_gen.outputs['examples'].get()[0].uri, 'Split-train')

# Get the list of files in this directory (all compressed TFRecord files)
tfrecord_filenames = [os.path.join(train_uri, name)
                      for name in os.listdir(train_uri)]

# Create a `TFRecordDataset` to read these files
dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")

# Iterate over the first 3 records and decode them.
for tfrecord in dataset.take(3):
  serialized_example = tfrecord.numpy()
  example = tf.train.Example()
  example.ParseFromString(serialized_example)
  pp.pprint(example)

Now that ExampleGen has finished ingesting the data, the next step is data analysis.

StatisticsGen

The StatisticsGen component computes statistics over your dataset for data analysis, as well as for use in downstream components. It uses the TensorFlow Data Validation library.

StatisticsGen takes as input the dataset we just ingested using ExampleGen.

statistics_gen = tfx.components.StatisticsGen(examples=example_gen.outputs['examples'])
context.run(statistics_gen)

INFO:absl:Excluding no splits because exclude_splits is not set.

INFO:absl:Running publisher for StatisticsGen
INFO:absl:MetadataStore with DB connection initialized

After StatisticsGen finishes running, we can visualize the outputted statistics. Try playing with the different plots!

context.show(statistics_gen.outputs['statistics'])

SchemaGen

The SchemaGen component generates a schema based on your data statistics. (A schema defines the expected bounds, types, and properties of the features in your dataset.) It also uses the TensorFlow Data Validation library.

SchemaGen will take as input the statistics that we generated with StatisticsGen, looking at the training split by default.

schema_gen = tfx.components.SchemaGen(
    statistics=statistics_gen.outputs['statistics'],
    infer_feature_shape=False)
context.run(schema_gen)

INFO:absl:Excluding no splits because exclude_splits is not set.

INFO:absl:Running publisher for SchemaGen
INFO:absl:MetadataStore with DB connection initialized

After SchemaGen finishes running, we can visualize the generated schema as a table.

context.show(schema_gen.outputs['schema'])

Each feature in your dataset shows up as a row in the schema table, alongside its properties. The schema also captures all the values that a categorical feature takes on, denoted as its domain.

To learn more about schemas, see the SchemaGen documentation.

ExampleValidator

The ExampleValidator component detects anomalies in your data, based on the expectations defined by the schema. It also uses the TensorFlow Data Validation library.

ExampleValidator will take as input the statistics from StatisticsGen, and the schema from SchemaGen.

example_validator = tfx.components.ExampleValidator(
    statistics=statistics_gen.outputs['statistics'],
    schema=schema_gen.outputs['schema'])
context.run(example_validator)

After ExampleValidator finishes running, we can visualize the anomalies as a table.

context.show(example_validator.outputs['anomalies'])

In the anomalies table, we can see that there are no anomalies. This is what we'd expect, since this the first dataset that we've analyzed and the schema is tailored to it. You should review this schema -- anything unexpected means an anomaly in the data. Once reviewed, the schema can be used to guard future data, and anomalies produced here can be used to debug model performance, understand how your data evolves over time, and identify data errors.

Transform

The Transform component performs feature engineering for both training and serving. It uses the TensorFlow Transform library.

Transform will take as input the data from ExampleGen, the schema from SchemaGen, as well as a module that contains user-defined Transform code.

Let's see an example of user-defined Transform code below (for an introduction to the TensorFlow Transform APIs, see the tutorial). First, we define a few constants for feature engineering:

_taxi_constants_module_file = 'taxi_constants.py'

%%writefile {_taxi_constants_module_file}

# Categorical features are assumed to each have a maximum value in the dataset.
MAX_CATEGORICAL_FEATURE_VALUES = [24, 31, 12]

CATEGORICAL_FEATURE_KEYS = [
    'trip_start_hour', 'trip_start_day', 'trip_start_month',
    'pickup_census_tract', 'dropoff_census_tract', 'pickup_community_area',
    'dropoff_community_area'
]

DENSE_FLOAT_FEATURE_KEYS = ['trip_miles', 'fare', 'trip_seconds']

# Number of buckets used by tf.transform for encoding each feature.
FEATURE_BUCKET_COUNT = 10

BUCKET_FEATURE_KEYS = [
    'pickup_latitude', 'pickup_longitude', 'dropoff_latitude',
    'dropoff_longitude'
]

# Number of vocabulary terms used for encoding VOCAB_FEATURES by tf.transform
VOCAB_SIZE = 1000

# Count of out-of-vocab buckets in which unrecognized VOCAB_FEATURES are hashed.
OOV_SIZE = 10

VOCAB_FEATURE_KEYS = [
    'payment_type',
    'company',
]

# Keys
LABEL_KEY = 'tips'
FARE_KEY = 'fare'

Writing taxi_constants.py

Next, we write a preprocessing_fn that takes in raw data as input, and returns transformed features that our model can train on:

_taxi_transform_module_file = 'taxi_transform.py'

%%writefile {_taxi_transform_module_file}

import tensorflow as tf
import tensorflow_transform as tft

import taxi_constants

_DENSE_FLOAT_FEATURE_KEYS = taxi_constants.DENSE_FLOAT_FEATURE_KEYS
_VOCAB_FEATURE_KEYS = taxi_constants.VOCAB_FEATURE_KEYS
_VOCAB_SIZE = taxi_constants.VOCAB_SIZE
_OOV_SIZE = taxi_constants.OOV_SIZE
_FEATURE_BUCKET_COUNT = taxi_constants.FEATURE_BUCKET_COUNT
_BUCKET_FEATURE_KEYS = taxi_constants.BUCKET_FEATURE_KEYS
_CATEGORICAL_FEATURE_KEYS = taxi_constants.CATEGORICAL_FEATURE_KEYS
_FARE_KEY = taxi_constants.FARE_KEY
_LABEL_KEY = taxi_constants.LABEL_KEY


def preprocessing_fn(inputs):
  """tf.transform's callback function for preprocessing inputs.
  Args:
    inputs: map from feature keys to raw not-yet-transformed features.
  Returns:
    Map from string feature key to transformed feature operations.
  """
  outputs = {}
  for key in _DENSE_FLOAT_FEATURE_KEYS:
    # If sparse make it dense, setting nan's to 0 or '', and apply zscore.
    outputs[key] = tft.scale_to_z_score(
        _fill_in_missing(inputs[key]))

  for key in _VOCAB_FEATURE_KEYS:
    # Build a vocabulary for this feature.
    outputs[key] = tft.compute_and_apply_vocabulary(
        _fill_in_missing(inputs[key]),
        top_k=_VOCAB_SIZE,
        num_oov_buckets=_OOV_SIZE)

  for key in _BUCKET_FEATURE_KEYS:
    outputs[key] = tft.bucketize(
        _fill_in_missing(inputs[key]), _FEATURE_BUCKET_COUNT)

  for key in _CATEGORICAL_FEATURE_KEYS:
    outputs[key] = _fill_in_missing(inputs[key])

  # Was this passenger a big tipper?
  taxi_fare = _fill_in_missing(inputs[_FARE_KEY])
  tips = _fill_in_missing(inputs[_LABEL_KEY])
  outputs[_LABEL_KEY] = tf.where(
      tf.math.is_nan(taxi_fare),
      tf.cast(tf.zeros_like(taxi_fare), tf.int64),
      # Test if the tip was > 20% of the fare.
      tf.cast(
          tf.greater(tips, tf.multiply(taxi_fare, tf.constant(0.2))), tf.int64))

  return outputs


def _fill_in_missing(x):
  """Replace missing values in a SparseTensor.
  Fills in missing values of `x` with '' or 0, and converts to a dense tensor.
  Args:
    x: A `SparseTensor` of rank 2.  Its dense shape should have size at most 1

  Returns:
    A rank 1 tensor where missing values of `x` have been filled in.
  """
  if not isinstance(x, tf.sparse.SparseTensor):
    return x

  default_value = '' if x.dtype == tf.string else 0
  return tf.squeeze(
      tf.sparse.to_dense(
          tf.SparseTensor(x.indices, x.values, [x.dense_shape[0], 1]),
          default_value),
      axis=1)

Writing taxi_transform.py

Now, we pass in this feature engineering code to the Transform component and run it to transform your data.

transform = tfx.components.Transform(
    examples=example_gen.outputs['examples'],
    schema=schema_gen.outputs['schema'],
    module_file=os.path.abspath(_taxi_transform_module_file))
context.run(transform)

Let's examine the output artifacts of Transform. This component produces two types of outputs:

transform_graph is the graph that can perform the preprocessing operations (this graph will be included in the serving and evaluation models).
transformed_examples represents the preprocessed training and evaluation data.

transform.outputs

{'transform_graph': OutputChannel(artifact_type=TransformGraph, producer_component_id=Transform, output_key=transform_graph, additional_properties={}, additional_custom_properties={}),
 'transformed_examples': OutputChannel(artifact_type=Examples, producer_component_id=Transform, output_key=transformed_examples, additional_properties={}, additional_custom_properties={}),
 'updated_analyzer_cache': OutputChannel(artifact_type=TransformCache, producer_component_id=Transform, output_key=updated_analyzer_cache, additional_properties={}, additional_custom_properties={}),
 'pre_transform_schema': OutputChannel(artifact_type=Schema, producer_component_id=Transform, output_key=pre_transform_schema, additional_properties={}, additional_custom_properties={}),
 'pre_transform_stats': OutputChannel(artifact_type=ExampleStatistics, producer_component_id=Transform, output_key=pre_transform_stats, additional_properties={}, additional_custom_properties={}),
 'post_transform_schema': OutputChannel(artifact_type=Schema, producer_component_id=Transform, output_key=post_transform_schema, additional_properties={}, additional_custom_properties={}),
 'post_transform_stats': OutputChannel(artifact_type=ExampleStatistics, producer_component_id=Transform, output_key=post_transform_stats, additional_properties={}, additional_custom_properties={}),
 'post_transform_anomalies': OutputChannel(artifact_type=ExampleAnomalies, producer_component_id=Transform, output_key=post_transform_anomalies, additional_properties={}, additional_custom_properties={})}

Take a peek at the transform_graph artifact. It points to a directory containing three subdirectories.

train_uri = transform.outputs['transform_graph'].get()[0].uri
os.listdir(train_uri)

['transform_fn', 'metadata', 'transformed_metadata']

The transformed_metadata subdirectory contains the schema of the preprocessed data. The transform_fn subdirectory contains the actual preprocessing graph. The metadata subdirectory contains the schema of the original data.

We can also take a look at the first three transformed examples:

# Get the URI of the output artifact representing the transformed examples, which is a directory
train_uri = os.path.join(transform.outputs['transformed_examples'].get()[0].uri, 'Split-train')

# Get the list of files in this directory (all compressed TFRecord files)
tfrecord_filenames = [os.path.join(train_uri, name)
                      for name in os.listdir(train_uri)]

# Create a `TFRecordDataset` to read these files
dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")

# Iterate over the first 3 records and decode them.
for tfrecord in dataset.take(3):
  serialized_example = tfrecord.numpy()
  example = tf.train.Example()
  example.ParseFromString(serialized_example)
  pp.pprint(example)

After the Transform component has transformed your data into features, and the next step is to train a model.

Trainer

The Trainer component will train a model that you define in TensorFlow (either using the Estimator API or the Keras API with model_to_estimator).

Trainer takes as input the schema from SchemaGen, the transformed data and graph from Transform, training parameters, as well as a module that contains user-defined model code.

Let's see an example of user-defined model code below (for an introduction to the TensorFlow Estimator APIs, see the tutorial):

Writing taxi_trainer.py

Now, we pass in this model code to the Trainer component and run it to train the model.

from tfx.components.trainer.executor import Executor
from tfx.dsl.components.base import executor_spec

trainer = tfx.components.Trainer(
    module_file=os.path.abspath(_taxi_trainer_module_file),

    train_args=tfx.proto.TrainArgs(num_steps=10000),
    eval_args=tfx.proto.EvalArgs(num_steps=5000))
context.run(trainer)

Analyze Training with TensorBoard

Optionally, we can connect TensorBoard to the Trainer to analyze our model's training curves.

# Get the URI of the output artifact representing the training logs, which is a directory
model_run_dir = trainer.outputs['model_run'].get()[0].uri

%load_ext tensorboard
%tensorboard --logdir {model_run_dir}

Evaluator

The Evaluator component computes model performance metrics over the evaluation set. It uses the TensorFlow Model Analysis library. The Evaluator can also optionally validate that a newly trained model is better than the previous model. This is useful in a production pipeline setting where you may automatically train and validate a model every day. In this notebook, we only train one model, so the Evaluator automatically will label the model as "good".

Evaluator will take as input the data from ExampleGen, the trained model from Trainer, and slicing configuration. The slicing configuration allows you to slice your metrics on feature values (e.g. how does your model perform on taxi trips that start at 8am versus 8pm?). See an example of this configuration below:

eval_config = tfma.EvalConfig(
    model_specs=[
        # Using signature 'eval' implies the use of an EvalSavedModel. To use
        # a serving model remove the signature to defaults to 'serving_default'
        # and add a label_key.
        tfma.ModelSpec(signature_name='eval')
    ],
    metrics_specs=[
        tfma.MetricsSpec(
            # The metrics added here are in addition to those saved with the
            # model (assuming either a keras model or EvalSavedModel is used).
            # Any metrics added into the saved model (for example using
            # model.compile(..., metrics=[...]), etc) will be computed
            # automatically.
            metrics=[
                tfma.MetricConfig(class_name='ExampleCount')
            ],
            # To add validation thresholds for metrics saved with the model,
            # add them keyed by metric name to the thresholds map.
            thresholds = {
                'accuracy': tfma.MetricThreshold(
                    value_threshold=tfma.GenericValueThreshold(
                        lower_bound={'value': 0.5}),
                    # Change threshold will be ignored if there is no
                    # baseline model resolved from MLMD (first run).
                    change_threshold=tfma.GenericChangeThreshold(
                       direction=tfma.MetricDirection.HIGHER_IS_BETTER,
                       absolute={'value': -1e-10}))
            }
        )
    ],
    slicing_specs=[
        # An empty slice spec means the overall slice, i.e. the whole dataset.
        tfma.SlicingSpec(),
        # Data can be sliced along a feature column. In this case, data is
        # sliced along feature column trip_start_hour.
        tfma.SlicingSpec(feature_keys=['trip_start_hour'])
    ])

Next, we give this configuration to Evaluator and run it.

# Use TFMA to compute a evaluation statistics over features of a model and
# validate them against a baseline.

# The model resolver is only required if performing model validation in addition
# to evaluation. In this case we validate against the latest blessed model. If
# no model has been blessed before (as in this case) the evaluator will make our
# candidate the first blessed model.
model_resolver = tfx.dsl.Resolver(
      strategy_class=tfx.dsl.experimental.LatestBlessedModelStrategy,

Now let's examine the output artifacts of Evaluator.

evaluator.outputs

{'evaluation': OutputChannel(artifact_type=ModelEvaluation, producer_component_id=Evaluator, output_key=evaluation, additional_properties={}, additional_custom_properties={}),
 'blessing': OutputChannel(artifact_type=ModelBlessing, producer_component_id=Evaluator, output_key=blessing, additional_properties={}, additional_custom_properties={})}

Using the evaluation output we can show the default visualization of global metrics on the entire evaluation set.

context.show(evaluator.outputs['evaluation'])

To see the visualization for sliced evaluation metrics, we can directly call the TensorFlow Model Analysis library.

import tensorflow_model_analysis as tfma

# Get the TFMA output result path and load the result.
PATH_TO_RESULT = evaluator.outputs['evaluation'].get()[0].uri
tfma_result = tfma.load_eval_result(PATH_TO_RESULT)

# Show data sliced along feature column trip_start_hour.
tfma.view.render_slicing_metrics(
    tfma_result, slicing_column='trip_start_hour')

SlicingMetricsViewer(config={'weightedExamplesColumn': 'example_count'}, data=[{'slice': 'trip_start_hour:19',…

This visualization shows the same metrics, but computed at every feature value of trip_start_hour instead of on the entire evaluation set.

TensorFlow Model Analysis supports many other visualizations, such as Fairness Indicators and plotting a time series of model performance. To learn more, see the tutorial.

Since we added thresholds to our config, validation output is also available. The precence of a blessing artifact indicates that our model passed validation. Since this is the first validation being performed the candidate is automatically blessed.

blessing_uri = evaluator.outputs['blessing'].get()[0].uri
!ls -l {blessing_uri}

total 0
-rw-rw-r-- 1 kbuilder kbuilder 0 Dec 29 10:13 BLESSED

Now can also verify the success by loading the validation result record:

PATH_TO_RESULT = evaluator.outputs['evaluation'].get()[0].uri
print(tfma.load_validation_result(PATH_TO_RESULT))

validation_ok: true
validation_details {
  slicing_details {
    slicing_spec {
    }
    num_matching_slices: 25
  }
}

Pusher

The Pusher component is usually at the end of a TFX pipeline. It checks whether a model has passed validation, and if so, exports the model to _serving_model_dir.

pusher = tfx.components.Pusher(
    model=trainer.outputs['model'],
    model_blessing=evaluator.outputs['blessing'],
    push_destination=tfx.proto.PushDestination(
        filesystem=tfx.proto.PushDestination.Filesystem(
            base_directory=_serving_model_dir)))
context.run(pusher)

Let's examine the output artifacts of Pusher.

pusher.outputs

{'pushed_model': OutputChannel(artifact_type=PushedModel, producer_component_id=Pusher, output_key=pushed_model, additional_properties={}, additional_custom_properties={})}

In particular, the Pusher will export your model in the SavedModel format, which looks like this:

push_uri = pusher.outputs['pushed_model'].get()[0].uri
model = tf.saved_model.load(push_uri)

for item in model.signatures.items():
  pp.pprint(item)
