Is MAC M1 supported for CTranslate2 installation ?

[harishankar-gopalan]

I tried installing CTranslate2 on MAC M1 but there doesnt seem to be an available package in pip repository. Do I need to recompile from source or is it not supported yet ?

Currently there are no prebuilt packages for Mac M1. You should compile the library from sources.

However, I have an experimental branch building ARM packages for macOS. Can you help testing? You can go to this build page, download the artifact "python-wheels", and install the appropriate "arm64" wheel.

Sure will check. I was able to install the CTranslate2 package of manylinux with arm64. But havent tested yet fully.

@harishankar-gopalan Did you have the time to install one of the macOS ARM64 wheel from the archive?

[harishankar-gopalan]

Hi @guillaumekln I was able to install the manylinux wheel after renaming it to the supported target name of Mac. I havent tested the above yet. Held up a bit in other priority works. Will surely update this thread once I test it out.

Hi @guillaumekln I was able to install the macOS ARM64 wheel from the archive you had listed previously in this thread. Also I did do a basic testing of a single batch of translations. It does work fine.
I guess a basic sanity testing is working. Just to note, I havent done a full blown latency/memory consumption kind of testing the macOS support is more of a development time requirement and not a production deployment.

Thanks for the feedback. If it seems to work fine, we will include these wheels in the next version.
