File is not a zip file - Githubissues

Hey! I have a private dataset in which I am using MeshCNN for classification. However, at epoch 4, a random error occurred:

zipfile.BadZipFile: Caught BadZipFile in DataLoader worker process 1.
Original Traceback (most recent call last):

zipfile.BadZipFile: File is not a zip file

And no, I don't have any zipfiles on my dataset. Any ideas?
