I also checked the uhd installation logs.
Why it couldn't find the uhd module?

    Hi USRP users,

    I am currently developing an OOT RFNoC module.
    When I tried to build a custom image, it gave me errors as below.
    I checked the python path, and it seems fine.
    Is there anyone that has any idea of the reason for this?
    I am using n310 with uhd v4.2.0.0.
    (I checked with uhd4.0, and didn't encounter this problem).

    Thanks in advance.
    Best regards.

Maybe your ld.so.conf doesn't include /usr/local/lib, or you didn't "sudo ldconfig" after doing the install?

What's in your PYTHONPATH?  Is that path actually *exported* or did you set it locally in your .bashrc (or equivalent).

If you manually go into python and:

import uhd

What happens?
