Running app.py gives the error "Can't load tokenizer"

Here's the full error:

$ python app.py 
Model directory '/home/zzz/ai/software/Pyramid-Flow/pyramid_flow_model' already exists. Skipping download.

OSError: Can't load tokenizer for '/home/zzz/ai/software/Pyramid-Flow/pyramid_flow_model/tokenizer'. If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name. Otherwise, make sure '/home/zzz/ai/software/Pyramid-Flow/pyramid_flow_model/tokenizer' is the correct path to a directory containing all relevant files for a CLIPTokenizer tokenizer.

And the contents of the folder in question:

$ ls -l pyramid_flow_model/tokenizer

The solution was to delete pyramid_flow_model and let app.py redownload it.
