Hi,
If you are not using CM 7.7.3.Please set the default python version to python2 and try running performance inspector.
--> run #alternatives --set python /usr/bin/python2

--> restart the agent : systemctl restart cloudera-scm-agent

Thanks

In fact, we're using CM7.7.3. We check the error and it seems like a good solution, but is there anything related to that specific version of CM?
