How to use meshroom_batch

[ad 1989]

Hello 

i have tried to use with prebuild version but i get this error (SyntaxError: Non-UTF-8 code starting with '\x88' in file /home/adarwich/Bureau/meshroom/meshroom_batch on line 2, but no encoding declared; see https://python.org/dev/peps/pep-0263/ for details
)?

and i find this (http://filmicworlds.com/blog/command-line-photogrammetry-with-alicevision/) it works fine, but with 2018 version not with 2021 version?

my goal is to launch all steps with a python script

Any idea?

Thanks
