Dataset extraction error

[Ishihara-Masabumi]

When I tried to run using the following command line,

python3 tools/train.py --config anomalib/models/padim/config.yaml

the following error saying "Unrecognized file format: datasets/MVTec/420938113-1629952094" occurrd.

Please let me know how to fix it !

Hi @Ishihara-Masabumi, looks like this happens when the code tries to download the MVTec dataset. Do you have the MVTec dataset on your file system? If yes, can you try to train the model using the same CLI command? If it works, we would know that the script only fails when trying to download the dataset.

Also reported in #838. @djdameln, can you have a look at this to check if this is a bug?

[Ishihara-Masabumi]

It's OK.
Thanks.
