`**ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

This issue seems to still exist. It is just a missing dependency though, and can be fixed via:
pip install ulog

Hi,

I have the same issue.
Installing ulog with pip does fix the problem but I get this error when executing:

AttributeError: module 'ulog' has no attribute 'enable_bridge'

Do you know if a certain version needs to be installed?

Thanks in advance!!

Have you been able to reproduce this issue lately with the latest 7.X releases ? (currently the 7.4.2?)

[iaamp]

At least for me, the issue seems to be fixed. Tested with Olympe 7.2.0, which was installed via pip parrot-olympe within a Python 3 (v.3.8.10) virtualenv on Ubuntu 20.04.

If i remember correctly, the issue occurred back when Olympe was relying on an install shell script, instead of a Python wheel.
