HW: Mac M1 SW: python 3.11

I'm trying to use this library, gecatsim, for handling CT file. Like the following code, I got incomplatible. I think the library isn't buildt for Mac m1.

Could you please provide new version for m1?

Yes, you are correct - the library is for the x86_64 architecture, and not M1. Having said that, you can build the library on your machine by following these steps.

Get the sources by git cloning this repository.
Go to the gecatsim/clib_build/src directory.
From there, run the command: make -f ../MakeMacOS libcatsim_macos.so
That should build the libcatsim_macos.so library for your M1 platform. Do let us know if you still have questions/issues.

Thank you for your answer. I moved lib files to site-packages/gecatsim/lib/ and it works well.
