Unable to import clr in MacOS for Automation.

[satyendra-rajpoot]

Hi, I am trying to run a simulation with DWSIM python package. While initialising the simulation and importing 'clr' I am getting this error. I have tried multiple version combinations of "PYTHONNET" and "MONO" but I am unable to resolve it.

Current MacOS version: macOS Monterey (Version 12.6.7)
PYTHONNET version: 3.0.0rc6
mono version: 5.14.0.177

It will be a great help if you can help me with this.

@satyendra-rajpoot try this: https://pythonnet.github.io/clr-loader/usage.html#getting-a-runtime

[satyendra-rajpoot]

Thanks for the quick reply sir.
I tried but I think I have some missing file... getting these errors:

while trying to assign runtime to get_mono()

while assigning runtime to get_coreclr()

@satyendra-rajpoot do you have mono installed? https://www.mono-project.com/download/stable/#download-mac

[satyendra-rajpoot]

Yes, I have following versions of 'mono' and 'pythonnet' in my device:

@satyendra-rajpoot please install mono from the above link

I installed mono from above mentioned link, while trying "clr_loader.get_mono()" got this error:

OSError: cannot load library '/Library/Frameworks/Mono.framework/Versions/Current/lib/libmonosgen-2.0.dylib': dlopen(/Library/Frameworks/Mono.framework/Versions/Current/lib/libmonosgen-2.0.dylib, 0x000A): tried: '/Library/Frameworks/Mono.framework/Versions/Current/lib/libmonosgen-2.0.dylib' (fat file, but missing compatible architecture (have (i386,x86_64), need (arm64e))), '/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/libmonosgen-2.0.1.dylib' (fat file, but missing compatible architecture (have (i386,x86_64), need (arm64e))). Additionally, ctypes.util.find_library() did not manage to locate a library called '/Library/Frameworks/Mono.framework/Versions/Current/lib/libmonosgen-2.0.dylib'

@satyendra-rajpoot so it seems that you have a ARM-based device... not sure if automation will work for you

[satyendra-rajpoot]

So is this a hardware limitation or do we have any workaround?

[satyendra-rajpoot]

Thanks a lot for your time.

I don't know for sure... unfortunately, I don't have an Apple ARM device to test it.
