No module named 'pqos'

After building appqos image in version v4.3.0 and using it in the container I see the following error:

Traceback (most recent call last):
  File "./appqos.py", line 47, in <module>
    import cache_ops
  File "/appqos_workspace/appqos/cache_ops.py", line 38, in <module>
    import caps
  File "/appqos_workspace/appqos/caps.py", line 37, in <module>

    from pqos import Pqos
ModuleNotFoundError: No module named 'pqos'
root@ar09-32-cyp:/opt/cek/intel-cmt-cat# 

I tried to follow this, but without success. Currently, I'm using Ubuntu 21.04. But I saw the same error on RHEL 8.4 as well. The build process has no errors.

Any suggestions?

I had the same problem before, you can check the installation of pqos by running pqos -V from the command line. At this point, you may get an error showing some information like, mount error, which I solved with docker -v /sys/fs/resctrl:/sys/fs/resctrl. But there may be some new problems later, I raised the issue.

The wiki page of resctrl may help you. https://github.com/intel/intel-cmt-cat/wiki/resctrl

@shaorui1 try to run this command before you build the image:

~/intel-cmt-cat# cp -r lib/python/pqos/ appqos/

it worked for me 😄
