Support for Mac ARM-64

[lfoppiano]

In this thread we should collect all issues related to MacOS ARM.

In general ARM is not yet supported. Please consider using Docker for the time being (https://grobid.readthedocs.io/en/latest/Grobid-docker/). Performances won't be the same due to the Rosetta interpreter.

Since nobody has a Mac ARM help is more than welcomed.

Thanks for flagging that this will not work. However, I also can't get the docker to work ...

After downloading the image (docker pull grobid/grobid:0.7.2-SNAPSHOT) I need to remove the GPUs from the command given in the docs for the server to start (docker run --rm --platform=linux/amd64 -p 8070:8070 grobid/grobid:0.7.2-SNAPSHOT). However, in that case, the Docker crashes as soon as TensorFlow is called:

The TensorFlow library was compiled to use AVX instructions, but these aren't available on your machine.
qemu: uncaught target signal 6 (Aborted) - core dumped

That seems to be a common issue ... but are you aware of how to get grobid to work on an M2 mac?

[LukasWallrich]

Just to note - the CRF-only image works on ARM Docker.

[lfoppiano]

@LukasWallrich the OS of the host machine you tried to run them, was it a macOs or Linux ARM?

[LukasWallrich]

Mac OS wit M2

Thank you @LukasWallrich

I am surprised that the current grobid image works on ARM, it should not :)
So I suppose the amd64 image is emulated? which would impact runtime.

My idea was to create multi-arch build images, but I've never tried to do it.
It's also hard to test for me I must say (I only have access to a M1 mac, the one of my wife but she's using it a lot ;).

[lfoppiano]

Yes I think docker has some part that is emulated. We're safe for the moment :-D

[LukasWallrich]

It is emulated - and therefore really rather slow ... but much better than nothing. Unfortunately I can't be of much use re the transition - don't really know any of the technology this is based on ...

Just to give an update from an M1 Pro user, the only thing that prevented me from running Grobid was libwapiti.dylib, which, once built on my machine, worked

[lfoppiano]

@jacksongoode in which directory did you copied it? Did you override the version under mac-64, under grobid-home/pdfalto?

[jacksongoode]

grobid-0.7.2/grobid-home/lib/mac-64/libwapiti.dylib

[lfoppiano]

@jacksongoode could you test the PR #975 ?

[jacksongoode]

@lfoppiano Sure! I'll get to it tomorrow!
