Failed to run annotator_webclient on Macbook with processor Apple Silicon [M1 Pro]

[1krupson]

I can't run a webclient on a Macbook with an M1 Pro processor. Is there any solution to this problem? Is it possible to run via rosetta?

I'm having this same issue. I believe the issue is with inotify, from my experience in projects at work (which also have inotify issues) there is no way to emulate it with rosetta. I think the only solution is to find a different work around without the inotify dependency. I'm not sure the use case in this software for inotify but it's a show stopper on M1 processors.

EDIT: I would like be proven wrong about this, it would help me at work as well 😅, but I don't think it's the case.

@1krupson turns out this is actually really easy to disable. You need to comment out the following line in the compose file.

(from this)
- FILE_WATCHER=true

(to this)
# - FILE_WATCHER=true

https://github.com/jsbroks/coco-annotator/blob/master/docker-compose.yml#L19

Setting it to false has no effect, it must be commented out, and that will disable the watcher which uses inotify.

Note that in development mode, this flag is overridden. See https://github.com/jsbroks/coco-annotator/blob/master/docker-compose.dev.yml#L38

So you really need to set it to false there.
