genicam package for python 3.11

[jack77er]

I know it is not really an harvesters bug, but I could not find any wheels or sources for the genicam 1.2.0 package for python 3.11 on windows. Is there any source or precompiled wheel available?

Thanks in advance

You can download the .whl file from pypi.

https://pypi.org/project/genicam/#files

Extract the latest version (.whl is just a .zip) and edit the METADATA file so it includes version 3.11:

Classifier: Programming Language :: Python :: 3.5
Classifier: Programming Language :: Python :: 3.6
Classifier: Programming Language :: Python :: 3.7
Classifier: Programming Language :: Python :: 3.8
Classifier: Programming Language :: Python :: 3.9
Classifier: Programming Language :: Python :: 3.10
Classifier: Programming Language :: Python :: 3.11

Zip the files and rename to .whl and install with:

pip install genicam-1.2.0-cp311-cp311-manylinux1_x86_64.whl

I do not recommend this method, if I would have to choose I would just use Python 3.10.

I did test it and the wheel for Genicam installed just fine, and I can import the harvester library and create a Harvester object. Other than that I did not test it.

Thanks for your response. Thats what I've tried, but the library is linked against the corresponding python library (python3xx.dll), in this case 3.10 as the last available:

When tying to load the module I've got the error

Process finished with exit code 1

Even when I try to cheat and copy the python310.dll into the package folder I've got a version mismatch error.

I see you are trying to get it working under Windows. I used Linux to test and it worked without any errors.

Is there a specific reason you need this to work on Python 3.11?

Hi guys, Python 3.11 will be supported by the next release in early 2023; we as the committee are working on it now, and the ARM64 binary should be bundled with it. By the way, I do not mind if you play the altered binaries but I would never bring up such an untrusty entity into the business. So scary. ;-)
