MayaCharm Import error

Coding
#1

Hi,
I’ve recently switched to PyCharm and I’ve installed the MayaCharm plugin, which I’ve been having problems with.

It runs fine with any default Python or Maya module i import, as well as any code i write. But I keep getting an ImportError: No modules named … whenever i import my own files.

My root folder is marked as source
Add contents roots to PYTHONPATH is checked
Add source roots to PYTHONPATH is checked

I can import my modules directly in Maya’s script editor, and load them in the python console for PyCharm.

I’m running this through the custom run/debug configuration that you setup for MayaCharm. I’m using ‘execute file’ to run main.py which imports all my other modules.

If anyone had any suggestion, i would really appreciate it!

I honestly know nothing about pycharm myself, but @passerby is MayaCharm’s author, so he might be able to offer some insight.

#3

So MayaCharm its self is having lots of problems with PyCharm 2019.3 which i have not been able to sort out yet.

but otherwise as long as what ever you are doing is in a place where Maya considers it part of its scripts path it should be fine. i tend to setup Maya modules that point to the paths where i am doing development for my Maya Scripts.

#4

I’m currently using PyCharm 2019.2.5 Community Edition with Maya 2019.

I’m not sure what’s causing the problem, whats annoying is that it was working last week.

Hopefully i can find a solution, ill update the thread if i do. In case anyone else has the same problem

#5

ok, so it’s now working.
The problem seemed to be with my import statements. I have a basic structure:

parent/
__init__.py
coreA.py
coreB.py
    sub-package/
    __init__.py
    coreC.py

I’m relatively new to python as I’ve started using it at work. But i realised it was because of the difference between absolute and relative imports, and when MayaCharm runs my script python changes the name to main

So i have to write this in coreA.py:
from parent import coreB

instead of:
import coreB

This explains why i could run it directly in Maya and in the Python Console.

Although, explicit relative imports doesn’t work:
from . import coreB

#6

Relative imports only work inside modules that are part of the same root package.
So in coreA you should be able to use from . import coreB if you are importing parent as a package, if however you’re attempting to run coreA.py on its own, or if you’ve added parent to sys.path you’ll run into issues.
