Hi, this looks like an SSL error. Are you behind a company proxy?

Some suggestions on stackoverflow are: ) install/update certifi: pip install --upgrade certifi ) use explicit ssl context (needs working certifi): change line 91 of "/home/max/git_ws/rvc_devkit/stereo/util.py" from url_object = urllib.request.urlopen(url) to url_object = urllib.request.urlopen(url, context=ssl.create_default_context(cafile=certifi.where()))

This needs two imports: import ssl import certifi

Does one of the steps work?

I updated the dev kit to allow skipping of ssl verification; define: export RVC_CUSTOM_SSL_SKIP_VERIFY=1
