Redlionfish on Mac M1 (arm64)

[haesleinhuepf]

Hi Luis @perdigao1 , hi all,

I just got a report from a collaborator that our napari-plugin distribution devbio-napari cannot be installed on Mac M1 because of an issue with RedLionFish. devbio-napari depends on redlionfish. The reported error was (I would provide more details if I could):

Encountered problems while solving:
  - nothing provides redlionfish needed by devbio-napari-0.1.5-pyhd8ed1ab_0

I know by chance that pyopencl works on Mac M1 and thus, was wondering why conda can't find a redlionfish that's compatible with this system. Can you give further insights?

No hurry btw. I removed redlionfish from the distribution temporarily so that the installation becomes functional again. I would be very happy to put it back in though!

Thanks!

Best,
Robert

Hi Robert,

Thank you for reporting that problem. I will have a look into it. I am currently fixing other issues with the code.

I have updated recently the RedLionfish in PyPI (PyOpenCL can now be installed using pip with the precompiled libraries) but not in conda but there should be a working version there. I will check github actions if any error occurred in Mac env.

You do say that it is arm64 (not intel), not sure if conda-forge compiles for that

Cheers
Luis

That might be the problem then. Maybe @jaimergp can assist us in making redlionfish deploy on Mac arm64? 🙃

The migration PR is there conda-forge/redlionfish-feedstock#5

It needs to be reviewed and merged by @perdigao1. I have ordered the bot to re-run it to make sure it's current. Once it lands again, you can review it!

There's also a pending version update (to be merged only after the osx-arm64 support PR).

Amazing, thanks for the lightspeed response @jaimergp ! 🤩

[perdigao1]

OK. I updated the package to version v0.8 and went through a maze of pushes, pulls and merges. I think I managed to get it right now., and I hope it is working. Thank you @jaimergp for fixing and to @haesleinhuepf for highlighting these issues.

Let me know if there are any problems.

Issued an automated fix for some permissions issue with the macOS scripts. conda-forge/redlionfish-feedstock#10

Btw, is RedLionFish using any compiled extensions? I think it qualifies for noarch, given that it seems to be pure Python. That would reduce the amount of builds to one or two. I do see you have conditional requirements (ocl-icd-system on Linux only), but that can be worked around with noarch_platforms as we did for devbio-napari. I can set this up for you if you are interested!

[perdigao1]

Yes. RedLionFish is python only. I don't know how to setup. Please feel free to setup.
