Załaduj zbiór danych

tfds.load

Najprostszym sposobem ładowania zestawu danych jest tfds.load . To będzie:

1. Pobierz dane i zapisać go jako tfrecord plików.
2. Załaduj tfrecord i stworzyć tf.data.Dataset .

ds = tfds.load('mnist', split='train', shuffle_files=True)
assert isinstance(ds, tf.data.Dataset)
print(ds)

<_OptionsDataset shapes: {image: (28, 28, 1), label: ()}, types: {image: tf.uint8, label: tf.int64}>
2021-10-01 11:11:25.312723: E tensorflow/stream_executor/cuda/cuda_driver.cc:271] failed call to cuInit: CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected

Kilka typowych argumentów:

• split= Które rozszczepiony do odczytu (np 'train' , ['train', 'test'] , 'train[80%:]' , ...). Zobacz nasz przewodnik Podział API .
• shuffle_files= : Kontrola, czy shuffle plików pomiędzy każdej epoki (TFDS przechowywanie dużych zbiorów danych w wielu mniejszych plików).
• data_dir= : Miejsce, w którym jest zapisany zestaw danych (domyślnie ~/tensorflow_datasets/ )
• with_info=True : Zwraca tfds.core.DatasetInfo zawierającą zestaw danych metadanych
• download=False : Wyłącz pobieranie

tfds.builder

tfds.load jest cienką owinięcie wokół tfds.core.DatasetBuilder . Można uzyskać taki sam efekt przy użyciu tfds.core.DatasetBuilder API:

builder = tfds.builder('mnist')
# 1. Create the tfrecord files (no-op if already exists)
builder.download_and_prepare()
# 2. Load the `tf.data.Dataset`
ds = builder.as_dataset(split='train', shuffle_files=True)
print(ds)

<_OptionsDataset shapes: {image: (28, 28, 1), label: ()}, types: {image: tf.uint8, label: tf.int64}>

tfds build CLI

Jeśli chcesz wygenerować konkretny zestaw danych, można użyć tfds wiersza poleceń . Na przykład:

tfds build mnist

Zobacz doc dla dostępnych flagami.

Iteruj po zbiorze danych

Jak dyktować

Domyślnie tf.data.Dataset obiektu zawiera dict z tf.Tensor s:

ds = tfds.load('mnist', split='train')
ds = ds.take(1)  # Only take a single example

for example in ds:  # example is `{'image': tf.Tensor, 'label': tf.Tensor}`
  print(list(example.keys()))
  image = example["image"]
  label = example["label"]
  print(image.shape, label)

['image', 'label']
(28, 28, 1) tf.Tensor(4, shape=(), dtype=int64)
2021-10-01 11:11:26.440171: W tensorflow/core/kernels/data/cache_dataset_ops.cc:768] The calling iterator did not fully read the dataset being cached. In order to avoid unexpected truncation of the dataset, the partially cached contents of the dataset  will be discarded. This can happen if you have an input pipeline similar to `dataset.cache().take(k).repeat()`. You should use `dataset.take(k).cache().repeat()` instead.

Aby dowiedzieć się dict nazwy klucz i struktury, spójrz na dokumentacji zestawu danych w naszym katalogu . Na przykład: mnist dokumentacji .

Jak krotki ( as_supervised=True )

Dzięki zastosowaniu as_supervised=True , można uzyskać krotki (features, label) zamiast pod kontrolą zbiorów danych.

ds = tfds.load('mnist', split='train', as_supervised=True)
ds = ds.take(1)

for image, label in ds:  # example is (image, label)
  print(image.shape, label)

(28, 28, 1) tf.Tensor(4, shape=(), dtype=int64)
2021-10-01 11:11:27.059200: W tensorflow/core/kernels/data/cache_dataset_ops.cc:768] The calling iterator did not fully read the dataset being cached. In order to avoid unexpected truncation of the dataset, the partially cached contents of the dataset  will be discarded. This can happen if you have an input pipeline similar to `dataset.cache().take(k).repeat()`. You should use `dataset.take(k).cache().repeat()` instead.

Jako numpy ( tfds.as_numpy )

Zastosowania tfds.as_numpy do konwersji:

• tf.Tensor -> np.array
• tf.data.Dataset -> Iterator[Tree[np.array]] ( Tree może być dowolna zagnieżdżone Dict , Tuple )

ds = tfds.load('mnist', split='train', as_supervised=True)
ds = ds.take(1)

for image, label in tfds.as_numpy(ds):
  print(type(image), type(label), label)

<class 'numpy.ndarray'> <class 'numpy.int64'> 4
2021-10-01 11:11:27.810923: W tensorflow/core/kernels/data/cache_dataset_ops.cc:768] The calling iterator did not fully read the dataset being cached. In order to avoid unexpected truncation of the dataset, the partially cached contents of the dataset  will be discarded. This can happen if you have an input pipeline similar to `dataset.cache().take(k).repeat()`. You should use `dataset.take(k).cache().repeat()` instead.

Jako dozowanego tf.Tensor ( batch_size=-1 )

Dzięki zastosowaniu batch_size=-1 , można załadować pełny zestaw danych w jednej partii.

To może być łączona z as_supervised=True i tfds.as_numpy aby uzyskać dane jako (np.array, np.array) :

image, label = tfds.as_numpy(tfds.load(
    'mnist',
    split='test',
    batch_size=-1,
    as_supervised=True,
))

print(type(image), image.shape)

<class 'numpy.ndarray'> (10000, 28, 28, 1)

Uważaj, aby zestaw danych mógł zmieścić się w pamięci, a wszystkie przykłady mają ten sam kształt.

Porównaj swoje zbiory danych

Benchmarking zestawu danych jest prosty tfds.benchmark wezwanie na dowolny iterable (np tf.data.Dataset , tfds.as_numpy , ...).

ds = tfds.load('mnist', split='train')
ds = ds.batch(32).prefetch(1)

tfds.benchmark(ds, batch_size=32)
tfds.benchmark(ds, batch_size=32)  # Second epoch much faster due to auto-caching

• Nie zapomnij o normalizacji wyników na wielkości partii z batch_size= kwarg.
• W podsumowaniu, pierwszy rozgrzewka partia jest oddzielone od pozostałych, aby uchwycić tf.data.Dataset dodatkowy czas konfiguracji (np bufory inicjalizacji ...).
• Wskazówki jak druga iteracja jest znacznie szybsze ze względu na TFDS automatycznego buforowania .
• tfds.benchmark zwraca tfds.core.BenchmarkResult który może być poddany kontroli w celu dalszej analizy.

Wyobrażanie sobie

tfds.as_dataframe

tf.data.Dataset przedmioty mogą być przekształcone w pandas.DataFrame z tfds.as_dataframe być wizualizowane na Colab .

• Dodaj tfds.core.DatasetInfo jako drugi argument tfds.as_dataframe wizualizację obrazów, audio, teksty, filmy, ...
• Zastosowanie ds.take(x) do wyświetlania pierwszego x przykłady. pandas.DataFrame załaduje pełny zestaw danych w pamięci i może być bardzo kosztowne wyświetlaczu.

ds, info = tfds.load('mnist', split='train', with_info=True)

Rozwiązywanie problemów

Pobieranie ręczne (jeśli pobieranie się nie powiedzie)

Jeśli pobieranie z jakiegoś powodu się nie powiedzie (np. offline,...). Zawsze można ręcznie pobrać dane siebie i umieścić go w manual_dir (domyślnie ~/tensorflow_datasets/download/manual/ .

Aby dowiedzieć się, które adresy URL pobrać, zajrzyj do:

• W przypadku nowych zestawów danych (realizowanych w folderze): tensorflow_datasets/ <type>/<dataset_name>/checksums.tsv . Na przykład: tensorflow_datasets/text/bool_q/checksums.tsv .

  Można znaleźć lokalizację źródłową zestawu danych w naszym katalogu .

• Dla starych zbiorów danych: tensorflow_datasets/url_checksums/<dataset_name>.txt

Mocowanie NonMatchingChecksumError

TFDS zapewnia determinizm, sprawdzając sumy kontrolne pobranych adresów URL. Jeśli NonMatchingChecksumError jest podniesiony, może wskazywać:

• Witryna może być w dół (np 503 status code ). Sprawdź adres URL.
• W przypadku adresów URL na Dysku Google spróbuj ponownie później, ponieważ Dysk czasami odrzuca pobieranie, gdy zbyt wiele osób uzyskuje dostęp do tego samego adresu URL. Zobacz bug
• Oryginalne pliki zestawów danych mogły zostać zaktualizowane. W takim przypadku konstruktor zestawu danych TFDS powinien zostać zaktualizowany. Proszę otworzyć nowy numer Github lub PR:
  • Zarejestrować nowe sumy kontrolne z tfds build --register_checksums
  • Na koniec zaktualizuj kod generowania zestawu danych.
  • Zaktualizować zestawu danych VERSION
  • Aktualizować DataSet RELEASE_NOTES : Co spowodowało sumy kontrolne do zmiany? Czy niektóre przykłady uległy zmianie?
  • Upewnij się, że nadal można zbudować zestaw danych.
  • Wyślij nam PR
