Having an issue with saving the model to file

[ontologist]

I get the following error when I run the example in the installation instructions. I think this has to do with different versions of /usr/local/lib/python3.8/dist-packages/gensim/utils.py distribution.

During handling of the above exception, another exception occurred:

IsADirectoryError: [Errno 21] Is a directory: './cache/output'

It seems that the 'fname_or_handle' parameter is not of the right kind. It is supposed to be a file object, for what I understand, but it is a string. The code that calls this is the OWL2Vec_Standalone.py script. I don't know how to fix this. Can you help, please?

I think "output" shoudl exist and perhaps the path is missing a "/" --> "./cache/output/"
