Issue Description

When I was using UHD Python API import uhd usrp = uhd.usrp.MultiUSRP("addr=192.168.9.2") This issue happened

Setup Details

Ubuntu: 20.04 UHD: 4.2 Python: 3.8

Expected Behavior

Actual Behaviour

Steps to reproduce the problem

Before you reproduce, please confirm your $home/.bashrc. It should be like this. image

Additional Information

After I change $home/.bashrc file like below, issue disappear and expected behavior goes well. image

Maybe the question is: If $PYTHONPATH contains /python3/dist-packages seems UHD Python API could not use normally in this case?

It looks like get_num_xbars was removed when UHD 4.0 was released. Notice in your actual output the UHD version printed is 3.15, which probably doesn't match your device. Perhaps you have remnants from multiple UHD versions on your system and changing your PYTHONPATH is affecting which one is being used.

In your logs, you are mixing UHD versions. I expect if you update your devices, you're good to go.
