How to install on M1 mac in python 3.9 environment?

[hiroalchem]

I tried to install it in the following way
conda create -n omero -c ome python=3.9 zeroc-ice36-python omero-py
I get the following error and cannot install, what should I do?

PackagesNotFoundError: The following packages are not available from current channels:

This is probably not much help, but that command worked fine for me:

$ which conda
/Users/wmoore/opt/anaconda3/condabin/conda
$ conda --version
conda 4.10.3

$ conda create -n omero2 -c ome python=3.9 zeroc-ice36-python omero-py
...
The following NEW packages will be INSTALLED:
...
zeroc-ice36-python ome/osx-64::zeroc-ice36-python-3.6.5-py39h141701c_7
...
$ conda activate omero2
...
$ omero login      # worked OK

$ pip freeze | grep zeroc
zeroc-ice @ file:///usr/local/miniconda/conda-bld/zeroc-ice36-python_1606217156867/work

I forget how I installed conda or whether I chose Anaconda or Miniconda (both appear above) but I think it was Anaconda

https://github.com/ome/conda-zeroc-ice36-python will need an osx-arm64 build to support M1 Macs

[hiroalchem]

@will-moore Thanks.
So, as @manics pointed out, it is still an M1 mac issue and needs to be built, right?
Is the conda-zeroc-ice36-python going to have an osx-arm64 build ready? Or should I build it myself? If there is a way to do this, I would be very grateful if someone could tell me how to do it.

[will-moore]

I don't know what @manics means. I just know that I have an M1 Mac and the commands above worked for me without having to "build" anything.

Did you install conda via Anaconda or miniconda. I think I used Anaconda.

[manics]

Sorry, I think @will-moore is right, it's possible to run cross-architecture binaries, see e.g. https://towardsdatascience.com/using-conda-on-an-m1-mac-b2df5608a141

[jburel]

I tested it again and it works for me too on M1
The command can actually be simplified i.e. conda create -n omero -c ome python=3.9 omero-py

[hiroalchem]

I have not been able to get it to work yet, could it be the Rosseta environment?

[jburel]

I have installed Anaconda. There is also https://github.com/conda-forge/miniforge#miniforge3 (I have not tried it).
What are you using?

[hiroalchem]

I have installed miniforge3.
I am not using Rosetta, is that the reason?

conda create -n omero -c ome python=3.9 omero-py

[jburel]

It could be, we are also new to M1.
We are using Rosetta.

[hiroalchem]

It worked well in the Rosetta environment. Thank you very much. However, due to other libraries, I want to run it in the M1 mac native environment. Is there any way to do this?

[hiroalchem]

After installing ice with brew, I installed zeroc-ice with pip and was able to install it in a native environment on M1 mac. However, in this case version 3.7.7 was installed. omero-py specifies version <3.7, is there a problem with 3.7?

[jburel]

There is no problem with Ice 3.7 as such. We do not support it. So unfortunately the setup using ice 3.7 won't work.

This issue has been mentioned on Image.sc Forum. There might be relevant details there:

[will-moore]

@hiroalchem You say you've been using miniforge3. Have you tried Anaconda (https://www.anaconda.com/products/individual#Downloads)?

[hiroalchem]

Thank you @manics, I was able to install from conda-forge.
