aravis python assertion errors

[nagyilles]

I am importing the package as follows:

from gi.repository import Aravis self.cam = Aravis.Camera.new(name)

The camera opened successfully (Baser acA1920-155um USB3) :

I am able to grab images, but I am getting the following error messages:

I have tried on 2 different machine with Ubuntu 20.04.1 LTS and different cameras.

Could you attach a short sample software that shows your issue ?

@nagyilles Did you figure out a way to resolve this issue.. ? I'm also facing similar issue while using basler and allied vision cameras..

@ayushbisht2001 Unfortunately not, but I did not worked on this code since and I did not see the EmmanuelP's message either. Could you answer his question?
