Error on NLP Subword Permission denied: ""tmp/spm".model": No such file or directory Error #2

I was going over the NLP chapter of the book and when I was getting to subword tokenizations I encounter an issue that I don’t know why its being cause

The error is happening after the function definition of subword in the 10_nlp chapter of the book I’m hoping someone can help me figure out whats going on or what I’m doing wrong.

I’ve installed sentencepiece and tried to reinstall but not working. Currently working on paperspace gradient.

Thanks a lot for your help

I am getting the same issue. Anyone figured out the issue?

Can you confirm you are using "sentencepiece<0.1.90" ??
