[Python] Use of pre-commit with PyCharm

I am trying to launch my pre-commit hooks from "commit" button in PyCharm (v. 2020.2). I use a conda venv (created with conda create -n py38 python=3.8) where I installed modules with pip install.

My .pre-commit-config.yaml reads:

repos:
- repo: local
hooks:
- id: black
name: black
language: system
entry: black --check
types: [python]

- id: isort
name: isort
language: system
entry: isort --check-only
types: [python]


I use local repo here because I will push my code to an intranet repository not connected to the internet.

Running pre-commit run --all-files runs fine from the command line on my local machine. But when I try to commit from PyCharm (), it raises the following error:

Traceback (most recent call last):

I think that this bug report on pre-commit's github is of particular relevance. If I understand well, it hints that PyCharm is not actually loading the venv and hence not finding installed packages in this environment. No solution is proposed though.

Anyone has a solution for that?
