[thiesmoeller]

Either use the commands like in the Readme https://github.com/basler/pypylon/blob/master/README.md#installation-from-source

Or call python setup.py install

compiling with python 3.9 and pylon5 ok, but still an error on import:

any idea to fix this? Thank you.

Edit: also with pylon 6 and latest pypylon repo

[lars-ek]

I still get the error with the latest repo and have no idea what to do :(

[thiesmoeller]

Is this under WSL?

[lars-ek]

macos 11.1 on m1-processor and python 3.9. No binary available:

~ $ pip3 install pypylon ERROR: Could not find a version that satisfies the requirement pypylon ERROR: No matching distribution found for pypylon ~ $

[thiesmoeller]

As we have no 11.1 pylon yet, I assume you have to stay in the intel domain on rosetta2

Your homebrew is native arm?

[lars-ek]

yes:

have you tried to install an intel-homebrew on your apple-silicon?

[barliya]

Hi,

I am facing the exact same problem with my M1 machine. I have both silicon and intel versions of homebrew. But I don't see how this should help, I am using the pip3 to install not brew. I am also running the terminal using Rosetta, and still not working.

Can you walk us through on how to install pypylon on m1 machines?

Thanks, Avi

[thiesmoeller]

Please post your command to install And the output you get.

[barliya]

Hi, For now I have managed to make it work under python 3.8 installed in a virtual environment (using pipenv). So it is working for me. However, I don't want it to be in the virtual env, so what I will try to do, is to downgrade my python from 3.9 to 3.8 and see if it also works for me in genral. I will report back. Thanks for the willingness to help.
