File "/home/dell/anaconda3/lib/python3.9/urllib/request.py", line 641, in http_error_default
raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

I get the following error when I try to generate results, can you let me know what is the reason for it? Is it due to not having the right link for pre trained model?
