tf.compat.v1.keras.utils.get_file

tf.keras.utils.get_file(
    fname, origin, untar=False, md5_hash=None, file_hash=None,
    cache_subdir='datasets', hash_algorithm='auto', extract=False,
    archive_format='auto', cache_dir=None
)

By default the file at the url origin is downloaded to the cache_dir ~/.keras, placed in the cache_subdir datasets, and given the filename fname. The final location of a file example.txt would therefore be ~/.keras/datasets/example.txt.

Files in tar, tar.gz, tar.bz, and zip formats can also be extracted. Passing a hash will verify the file after download. The command line programs shasum and sha256sum can compute the hash.

Example:

path_to_downloaded_file = tf.keras.utils.get_file(
    "flower_photos",
    "https://storage.googleapis.com/download.tensorflow.org/example_images/flower_photos.tgz",
    untar=True)

Arguments
fname	Name of the file. If an absolute path /path/to/file.txt is specified the file will be saved at that location.
origin	Original URL of the file.
untar	Deprecated in favor of extract argument. boolean, whether the file should be decompressed
md5_hash	Deprecated in favor of file_hash argument. md5 hash of the file for verification
file_hash	The expected hash string of the file after download. The sha256 and md5 hash algorithms are both supported.
cache_subdir	Subdirectory under the Keras cache dir where the file is saved. If an absolute path /path/to/folder is specified the file will be saved at that location.
hash_algorithm	Select the hash algorithm to verify the file. options are 'md5', 'sha256', and 'auto'. The default 'auto' detects the hash algorithm in use.
extract	True tries extracting the file as an Archive, like tar or zip.
archive_format	Archive format to try for extracting the file. Options are 'auto', 'tar', 'zip', and None. 'tar' includes tar, tar.gz, and tar.bz files. The default 'auto' corresponds to ['tar', 'zip']. None or an empty list will return no matches found.
cache_dir	Location to store cached files, when None it defaults to the default directory ~/.keras/.

Returns
Path to the downloaded file
