state of osx-arm64

[ReimarBauer]

We got a request by a participant of the CAESAR campaign, Feb 20-April 7, if MSS can be installed on an M2 apple.

Currently this is not possible. I suggested to use our docker image, https://mss.readthedocs.io/en/stable/installation.html#docker-instance

Recently basemap with 1.3.9 was added for osx-arm64.

We have to review what blocks us to use a ARM OSX Migrator for our package, similiar to conda-forge/basemap-feedstock#123

[ReimarBauer]

The dockerimage has currently INFO: MSS Version: 8.3.2

and was updated to 8.3.3

[ReimarBauer]

tried manually https://conda-forge.org/blog/2020/10/29/macos-arm64/ which might work

conda-forge/mss-feedstock#168

There are some not on the list, so trying the bot now.

[ReimarBauer]

looks like we can cross compile this conda-forge/mss-feedstock#168
The question is how can we check it.

[ReimarBauer]

Another option could be
https://conda-forge.org/docs/user/tipsandtricks.html#installing-apple-intel-packages-on-apple-silicon

[ReimarBauer]

Looking on https://anaconda.org/conda-forge/pyqt/files?page=4

the first osx-arm64 is a pyqt-5.15.4 version.

Version 8.X.X can't be used with this type of processor because we need there a pinning of pyqt >=5, <5.13
This changes with version 9.

Hello,
my working laptop is also with M2 apple and I've encountered the same issue. We will have a flight campaign this summer (ORCESTRA campaign), where we would like to use MSS. Do you have a rough estimate, when this issue could be solved?

[ReimarBauer]

Hi @yu71ng
we plan to release 9.0.0 in the next weeks.
There are a few issues remaining https://github.com/Open-MSS/MSS/milestone/93

Help is welcome :)

[yu71ng]

Maybe for an in-between solution, it came to my attention to do as follows: https://stackoverflow.com/questions/71515117/how-to-set-up-a-conda-osx-64-environment-on-arm-mac

Just change the setting in the mss-environment before installing the mss software:

conda config --env --set subdir osx-64

With that, I can run mss 8.X.X. on a M2 Apple :)

[ReimarBauer]

Great @yu71ng , thx to letting us know :)

[ReimarBauer]

After the release of 8.3.5 and its cross compilation we can verify if missing packages are available.

Hi there! I'm in the process of trying to install MSS on my Apple M2 chip. Based on the suggestions from @yu71ng, I tried the following

conda config --env --set subdir osx-64
conda config --add channels conda-forge
conda create -n mssenv
conda activate mssenv
conda install mss=9.3.0 python --solver=libmamba

Then I'm getting the following error

I'm tried to install a few different ways with mamba or conda now, so maybe I need to do full clean our of the mssenv dir on my system before I try to install again?

Hi @ccostanza10
this issue is closed because we updated the package and the installation description. We will do for version 10 another update to the installation description because we got aware that the packages of conda-forge and anacondas default are mismatching.
https://conda-forge.org/docs/user/transitioning_from_defaults/#a-historical-note

I do have a M4 myself and for me the manual installation works, but I also have no anaconda license or anaconda pre installed. I am not sure if conda config --env --set subdir osx-64 makes now problems.

Because of the anaconda defaults and conda-forge mismatch and because of the features of pixi for development we will change to a pixi installation for version 10.

This gets into the documentation in the next release after we merged

https://github.com/Open-MSS/MSS/pull/2632/files#diff-d9b149498982c0663c3b7170398773361ed5678f1a627e9c2fd8d2c955c563db

please try the pixi installation described there.

[ccostanza10]

Hey @ReimarBauer!

Right, I tried the manual install with miniforge3 first, and I got the same error. That I listed in the previous mesage.

I did just try the pixi global install mss, and that worked without error! Excellent! Thanks for your help in figuring this out. Looking forward to testing out MSS.
