Hi @fgr1986, thank you for your question. This is a difficult question since we do not have a machine to do the tests ourselves. However, from the error messages, it looks like you did not create an environment with Python 3.8. Could you please make sure you have a clean environment? You can follow this tutorial: https://oommfc.readthedocs.io/en/latest/ipynb/installation-testing-update.html

Please keep us updated.

[fgr1986]

Hi @marijanbeg , thanks for your quick responses. This was in a clean environment, and I tried with both 3.9 and 3.8. The installation with pip fails on hp5 libs (will report it).

I will update the tread if I find anything from the log. Thanks

[marijanbeg]

Hi @fgr1986, I transferred this issue to our help repository. Is this issue still active?

[fgr1986]

Hi, yes, I just tried to install it and it is still a problem.

[AkravasTheWise]

tl:;dr you're out of luck. Try to get a computer with amd or armv8

Any arm chip lower than v8 presents this problem with the piwheels of hp5. I encountered this while trying to run Ubermag in a Raspberry Pi 4. I got further installing missing packages from the piwheels website, but run into more problems since there was no actual software for arm64 architecture to emulate that library. I am hoping that I can make the rig work and upload a tutorial when I can get my hands on the new Pi 4B with ARMv8

[nickfanion]

This is still an issue in 2023. I'm unable to install oommfc, and therefore ubermag, on Apple Silicon (osx-arm64) machines. Apple doesn't sell Intel machines anymore. I'm using miniforge, so conda-forge is the default channel.

conda install oommfc -v

I was able to install ubermag via pip, compile oommfc from source, and add oommfc to my path, but ubermag.test() returned several errors and warnings.

[fangohr]

I can reproduce your error using miniforge.

The installation works fine using normal anaconda:

conda create -c conda-forge -n myubermag python=3.10 conda activate myubermag conda install -c conda-forge oommfc

Once this is done, I could run:

$ python

Could you try to use anaconda (or mini conda) instead of mini forge?

[nickfanion]

Thanks @fangohr

I tried your installation steps, with miniconda and the full Anaconda distribution. Unfortunately, it didn't make a difference on my machine, and the same error occurred. I ran anaconda-clean and removed all config files before trying a new conda installer.

conda version = 23.5.0 macOS version = Ventura 13.4.1 MacBook Air with M2

Attached is the output with the -vv flag:

oommfc-vv-log.txt

[fangohr]

Thanks. I could recreate this error now on a fresh user account. Installed anaconda from https://repo.anaconda.com/archive/Anaconda3-2023.03-1-MacOSX-arm64.sh

Then commands as above:

conda create -c conda-forge -n myubermag python=3.10
conda activate myubermag
conda install -c conda-forge oommfc -vv &> anaconda-install-oommfc.log

anaconda-install-oommfc.log

conda version = 23.3.1 macOS version = Ventura 13.4.1 MacBook Air with M2

Re-running the command after setting conda config --set unsatisfiable_hints True does not change what is captured in the output.

[nickfanion]

I tried mamba and received a more detailed error message:

I did some more tests by building OOMMF from source.

Built OOMMF (Terminal output attached): git clone https://github.com/fangohr/oommf.git cd oommf make build oommf build log.txt

Ran the make test (test output attached): make test-all boxsi.errors.txt

Added the OOMMFTCL path variable to .zshrc in my home directory and restarted Terminal: export OOMMFTCL="/Users/nick/compiled-apps/oommf/oommf/oommf.tcl"

Installed ubermag with pip in a clean python 3.10 environment: conda create -n ubermag_env python=3.10 conda activate ubermag_env pip install ubermag

Ran test to see if ubermag can find OOMMF. It returned an error: python3 -c "import oommfc; oommfc.oommf.status()"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: module 'oommfc.oommf' has no attribute 'status'

[lang-m]

Two short notes on the test problems:

1. oommfc.oommf.status() is not the right command (the naming is maybe a bit confusing). Instead, you can use one of:
   • python3 -c "import oommfc; oommfc.runner.runner.status"
   • python3 -c "import oommfc; oommfc.runner.autoselect_runner(); print(oommfc.runner)"
2. The ImportError shown in the test output is known and will be fixed in the next release. It does not affect running simulations.

[nickfanion]

Thanks @lang-m. This is my output from python3 -c "import oommfc; oommfc.runner.runner.status"

[lang-m]

That looks like OOMMF is found and running (same meaningless ImportError at the end). If you try the other command, you should see the full path to oommf.tcl in the output. That might be useful to confirm that oommfc did indeed pick up the right version (in case you were to have multiple copies of OOMMF).

[nickfanion]

Yes, it did find the correct (and only) OOMMF:

OOMMF runner: TclOOMMFRunner(/Users/nick/compiled-apps/oommf/oommf/oommf.tcl)
runner is cached: True

My only outstanding issues are the 11 failures ubermag.test() returns. However, I assume some are meaningless (like the exe runner), and I haven't run into any issues with my projects yet.

[DebanjanPolley]

Recently, I found an easier way to install UBERMAG on a Mac (M1/M2 chip).

I had to build an osx-64 environment within my M2 Mac in the following way:

1. Create an osx-64 virtual environment ubermag_env CONDA_SUBDIR=osx-64 conda create -n ubermag_env python
2. activate the virtual environment conda activate ubermag_env
3. config osx-64 conda config --env --set subdir osx-64

Then use $ conda install --channel conda-forge ubermag to install UBERMAG.
