I've also encountered this error, and here I made a very stupid mistake.
If you're using a windows environment, don't use WinRAR to extract the dataset (I haven't tried other software, but WinRAR can extract a file but this file can't be used for training), use tar -xvzf path/to/vggface2_crop_arcfacealign_224.tar instead!

Here is the solution:

1. "AttributeError: 'EfficientNet' object has no attribute 'act1'", it can be solved by @1YasserAmmar1 in #307
2. "num_samples should be a positive integer value, but got num_samples=0", add this command before training,
   !mv /content/vggface2_crop_arcfacealign_224/ /content/TrainingData/vggface2_crop_arcfacealign_224
