Issues with blender python api

[LucaBonfiglioli]

• pipelime version: 1.9.1
• Python version: 3.10
• Operating System: Ubuntu 22.04

Description

If bpy is imported, pipelime won't be able to run with multiprocessing.

What I Did

1. Create a file named bug.py with the following statement

import bpy

2. Running the following command

pipelime -m bug.py clone +i folder1 +o folder2 +g 8,1

Will result in the following error message:
