Re: [Fab-user] error importing custom modules

[Todd DeLuca]

Try either using 'Fabexec' or importing 'modules.Fabexec' in set_nic_buffers.py.  Currently you seem to be importing 'Fabexec' but using 'modules.Fabexec'.

For example, in set_nic_buffers.py, change `from modules import Fabexec` to `import modules.Fabexec`

Alternatively, have modules/__init__.py import Fabexec, so it is present in the 'modules' namespace when you `import modules`.

Regards,

Todd

My paths all seem to be fine not sure what’s going on
