"arch" depended configuration for the sections "python", "before_install" and "virtualenv"

Languages Python
1

I couldn’t find an example for that in the docs. Sorry.

I want to do something like this where the Python 3.8 interpreter is selected only for the ppc64le architecture and with system-site-packages activated.

language: python
os: linux
arch :
 - amd64
 - ppc64le

dist: focal

python:
  amd64:
    - "3.6"
    - "3.9"
    - "3.10"
  ppce64le:
     - "3.8_with_system_site_packages"

Or something like this

language: python
os: linux
arch :
 - amd64
 - ppc64le

dist: focal

python:
  amd64:
    - "3.6"
    - "3.9"
    - "3.10"
  ppce64le:
     - "3.8"

virtualenv:
  ppce64le:
    system_site_packages: true

And in result of that I need arch depended before_install and install sections like this

before_install:
   amd64:
    - python3 -m pip install PyQt5
   pcc64le:
    - sudo apt install python3-pyqt5
