The way the data loading is done is with a bunch of nested try/except blocks, which I feel like is something we would like to avoid in general but it felt valid here.

Also this cli command is really short and simple compared to the rest so I feel like I must have missed a lot of things.

I think it would make more sense to go by file ending here (maybe .spacy vs. not-.spacy) and take it from there?

okok and then only the decode error remains in the tryexcept
