Command "launch auto " interrupted with error: TypeError : a bytes-like object is required, not 'str'

Asked by Luis Felipe Coelho on 2021-01-25

Hi,

I am trying to generate this process: p p > t t~ > w+ b w- b~ [QCD]
However I am getting the following error.

Command "launch auto " interrupted with error:
TypeError : a bytes-like object is required, not 'str'

Cheers,
Luis

I will release (hopefully today) 2.8.3 which will fix that issue (and other similar python3 issue).
If you have python2.7 available on your system you can force that python version that should not have such issue.

Cheers,

Olivier

Thanks Olivier Mattelaer, that solved my question.
