python - ImportError: No module named 'hal'

[klemen dovrtel]

Hello everybody,

I am testing a simple passthrough python module. When I start $halrun and

halcmd: loadusr passthrough.py

I get an error message:

import hal
ImportError: No module named 'hal'

Does anybody have an idea what is the problem when I try to load the python module from hal? When I start $python instead and try to >>> import hal within python, I get no complaints about missing hal module.

Regards

Klemen

Hello everybody,

I think I found the problem myself :) That particular python script was run from python3 (#!/usr/bin/env python3).

I changed this to #!/usr/bin/env python2.7 and now I don't get this error message any more.
