@frgfm thanks a lot that's really helpful :)

some mypy issues left

[felixdittrich92]

@frgfm I have canceled the jobs (runs since ~2hrs to find matching packages for tf):

[felixdittrich92]

@frgfm again :/
I think it would be helpful to upgrade tf first 😅 (we can exclude TF mobilenet models onnx export tests ftm to pass the tensorflow tests)

[frgfm]

All good now 👍

[felixdittrich92]

Thanks a lot really nice 👍
Only one question what about flake (looks like it was not triggered) ? :)

[frgfm]

Thanks a lot really nice +1 Only one question what about flake (looks like it was not triggered) ? :)

It has been, but I changed the python runtime and renamed the job, so we have to update the "required" jobs :)
