This otherwise works fine when launched from command line.

That's very strange.
I could not reproduce it.
Could you add these line to your code (before you import numpy), run it and confirm that your venv path is in there?

import sys
print(sys.path)

[NekiMedo]

added code:

import sys
print( sys.path )
a = input( 'press ENTER' )

the output:

$ reloadium run ./udp_text_receiver.py

likely it has to do with the version of Python being used; some modules i use don't work with Python 3.10 so i use Python 3.9.12 in virtual environment - which is what gets picked up when running without reloadium. Looks like reloadium kicks off Python 3.10 - it should probably be picking the interpreter found at $VIRTUAL_ENV/bin PATH

BTW this is running on Debian bookworm (probably doesn't matter)

I think the issue here is that reloadium was installed in a wrong environment.
By invoking your script with ./udp_text_receiver.py your script is run by python3.9 (from the shebang) and by invoking with reloadium it uses venv where reloadium was installed which is 3.10.
I think if you install reloadium in 3.9 one it should work fine.

[NekiMedo]

you are right - removing the user-wide installation and re-installing it within the virtual environment sorted things out;
thanks for your help
