Module: tfdf.inspector

Model inspector.

Utility to access the structure and meta-data (e.g. variable importance, training logs) of a model.

Usage:

model = keras.RandomForest().
model.fit(...)
inspector = model.make_inspector()

# Or
inspector = make_inspector(<model directory>)

print(inspector.name())
print(inspector.num_trees())
# Note: "inspector"'s accessors depends on the model type (inspector.name()).

Classes

class Evaluation: Evaluation of a model.

class IterNodeResult: Value returned by node iterator methods. See "iterate_on_nodes".

class SimpleColumnSpec: Simplified representation of a column spec.

class TrainLog: One entry in the training logs of a model.

Functions

detect_model_file_prefix(...): Auto-detects the model's file prefix if possible.
