partially initialized module 'json' has no attribute 'loads' - not naming problem

Question

i'm getting AttributeError: partially initialized module 'json' has no attribute 'loads' (most likely due to a circular import), i searched a lot on google an nothing worked. I don't have any module called json or something like that so that's not the problem.

My system is Macos . And i try to run Qgis modules with pycharm. This is the full error:

  File "/Users/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/projs/project.py", line 3, in <module>

    loads = json.loads
AttributeError: partially initialized module 'json' has no attribute 'loads' (most likely due to a circular import)

Any ideas? I think it psycopg2 thing but couldn't find a solution

Try changing the "from ... import ..." to simply "import ..." — CozyCode, Dec 11 '21 at 08:07
What is the minimum code you need to cause the problem? Can you give steps to reproduce the problem, starting with installing the libraries on a new system? — Karl Knechtel, Dec 11 '21 at 08:42
@KarlKnechtel All i did was adding Qgis to the interpreter path and installed things like Psycopg2, Pyqt, config. As you can see in the errors most of the errors come from psycopg2 — Micha, Dec 11 '21 at 10:44
@CozyCode didn't work, it seems like the errors come from psycopg2 and json not my code directly. All i do in my code is to import json — Micha, Dec 11 '21 at 10:46

After looking at my interpreter paths i noticed that i have path that leads to psycopg2 in another version of python.

After deleting the path everything worked.

Preferences -> Python interpreter -> settings icon -> show all -> show paths of selected .. -> delete the path
