I have some difficulty with tensorflow_datasets when I was trying to load mnist.
python:3.7 tensorflow : 2.1.0
tensorflow_datasets has been upgraded to latest version 4.6, because the default version of tensorflow_datasets from tensorflow installation has no attribute 'load'
But now the problem is data can not be downloaded and extracted successfully. with the following command:
datasets = tfds.load(name="mnist")
the error message is : Downloading and preparing dataset Unknown size (download: Unknown size, generated: Unknown size, total: Unknown size) to ~\tensorflow_datasets\mnist\3.0.1... Extraction completed...: 0 file [00:00, ? file/s]██████████████████████████████████████████████████████████████| 4/4 [00:00<00:00, 138.37 url/s] Dl Size...: 100%|██████████████████████████████████████████████████████████████████████████| 11594722/11594722 [00:00<00:00, 373172106.07 MiB/s] Dl Completed...: 100%|█████████████████████████████████████████████████████████████████████████████████████████| 4/4 [00:00<00:00, 122.03 url/s] Traceback (most recent call last): File "", line 1, in File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\core\load.py", line 327, in load dbuilder.download_and_prepare(**download_and_prepare_kwargs) File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\core\dataset_builder.py", line 483, in download_and_prepare download_config=download_config, File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\core\dataset_builder.py", line 1222, in _download_and_prepare disable_shuffling=self.info.disable_shuffling, File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\core\split_builder.py", line 310, in submit_split_generation return self._build_from_generator(**build_kwargs) File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\core\split_builder.py", line 376, in _build_from_generator leave=False, File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tqdm\std.py", line 1195, in iter for obj in iterable: File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\image_classification\mnist.py", line 151, in _generate_examples images = _extract_mnist_images(data_path, num_examples) File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_datasets\image_classification\mnist.py", line 350, in _extract_mnist_images f.read(16) # header File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_core\python\lib\io\file_io.py", line 122, in read self._preread_check() File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_core\python\lib\io\file_io.py", line 84, in _preread_check compat.as_bytes(self.__name), 1024 * 512) File "C:\Users\Wilso\Anaconda3\envs\tfgpu\lib\site-packages\tensorflow_core\python\util\compat.py", line 87, in as_bytes (bytes_or_text,)) TypeError: Expected binary or unicode string, got WindowsGPath('C:\Users\Wilso\tensorflow_datasets\downloads\extracted\GZIP.cvdf-datasets_mnist_train-images-idx3-ubyteRA_Kv3PMVG-iFHXoHqNwJlYF9WviEKQCTSyo8gNSNgk.gz')

请尝试：

(ds_train, ds_test), ds_info = tfds.load(
    "mnist",
    split=["train", "test"],
    shuffle_files=True,
    as_supervised=True,  # will return tuple (img, label) otherwise dict
    with_info=True,  # able to get info about dataset
)
