basemap with mac m2 issues

[swiftienimbus]

Hello I am not an expert in programming so I am kindly asking for some help. I just purchased a new laptop (Macbook pro chip M2 pro). I want to install all the programs and packages I used to work with my old macbook air. So I am trying to install basemap (I already tried to install python 3.5 and is already installed in an environment) but i am still getting this error:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/gm/t4q3k1t913b67p1g_j4_gp840000gn/T/pip-build-ain2mraz/matplotlib/

Can I get some help? I have no idea how to solve it, i already installed as well cython but still I don't get any success to install basemap. I want to work with this new laptop to finalize a paper and I really need this package!

Thanks in advance

Hi @swiftienimbus! Can you provide the whole traceback that you get when trying to install basemap? With a bit more info I can try to help you see where the problem is coming from.

Note that we do not have basemap wheels for MacOS on PyPI, so the installation is not simply to download the wheel, but your computer needs to build the wheel from source, which can fail due to several reasons (GEOS missing, GEOS not being found, lack of C/C++ compiler, etc.).

Since you are using a brand new computer, I would also recommend that you try to use a newer Python version (3.8+). Python 3.7 will be EOL this June 2023, Python 3.5 has been EOL for almost 3 years.

Thank you for your reply so I installed python 3.5 in an environment because I thought maybe this way basemap would be installed with less issues. I tried to use the following:

Should I install geos? or something else? I am using M2 pro chip. I was trying to install the python version I wanted for this environment with pyenv but now when I type

python --version I get this : pyenv: python: command not found

The `python' command exists in these Python versions: 3.5.10

Note: See 'pyenv help global' for tips on allowing both python2 and python3 to be found.

Sorry for the inconvenience! your help is appreciated! Now I tried to set to local the python version but I am not sure whether I have to do this everytime I open the environment?

From your traceback, the issue is coming from the missing GEOS library. In the precompiled wheels, a copy of GEOS is bundled for basemap use. In your case, since there are no wheels for MacOS, you need to build from the source distribution, and GEOS needs to be present somewhere in your system so that pip can try to build the _geoslib extension.

GEOS should be easily installable on MacOS, e.g. through Homebrew. Once you have it, you will need to find out its root installation folder, and define the GEOS_DIR environment variable with this folder path before calling pip to install basemap.

I already followed your instructions and these ones: https://github.com/matplotlib/basemap/issues/539

I installed as well freetype and other packages but I am still gettint this error:

Should I change another file? or is it because the python version is not compatible ? Can I kindly ask for your help since I am not that expert in changing configurations in files :( sorry and thanks for the quick reply!

[molinav]

The problem that you are getting here is different and caused by your Python 3.5 installation. In your last message, you are using Python 3.5 and not Python 3.9 (from your traceback). The support for Python 3.5 in matplotlib was dropped long ago (3.1 if I remember correctly), and at the time there were no wheel builds for the new Apple ARM chips. Because of that is why you are needing to install all the matplotlib build dependencies when trying to install basemap, since matplotlib also needs to be built from source for this old Python version.

I would recommend that you recheck your environment and ensure that you are using Python 3.9 as in your previous message that had the GEOS_DIR error message. Once you are sure that this is correct, I would recommend that you try with the GEOS installation through Homebrew or similar, and then the setup of the GEOS_DIR environment variable to the appropriate folder path.

[swiftienimbus]

Yes thanks, I already did those steps, I checked the version in my current environment and is Python 3.5.10

Do you suggest changing to the python 3.9 version? I am still getting this error (I attach the screenshots)

I am tryint to track that file that shows the error to maybe modify it but I can't find it, maybe I'll create a new environment with a higher python version but just want to make sure is because of the python version.

The complete message is here:

Unless you have a real reason to use Python 3.5, better switch to at least Python 3.9. Otherwise you will have to face these problems not only with basemap but almost with any package, since you will not find MacOS ARM64 wheel packages for any dependency and your system will need to build everything always from source.

Once you have switched to at least Python 3.9, you can try again what you already tried for Python 3.5 and, if the problem persists, feel free to copy the traceback here and I will try to help you.

Hello thank you so much for your help!

I actually tried to solve that installing a new version of python (i am using pyenv, but i am not very familiar with this, and is giving me problems when I start a new shell window). I tried to install python 3.9 in the nimbus environment and at the end everything was successful until when I want to import basemap via spyder or jupyter notebook, it's giving me this error:

I am not sure if is related to something to the basemap path's that spyder and jupyter notebook can't recognize is already installed, because when I run the program in terminal via:

python scriptfile.py I don't get errors while importing basemap, (but still i am having errors in other parts which would be more easy to see if I could visualize and import everything correctly in spyder) should I do something else? do you recommend installing python versions with pyenv? or how can i solve this issue related to importing the package in spyder? Thanks again in advance!

[molinav]

Hi @swiftienimbus! For the problem with Spyder and Jupyter notebooks I cannot provide much help because I do not use them regularly. Normally I play around directly using IPython in my console or by running scripts without interaction.

From what you describe, since your scriptfile.py can import basemap without error, I would assume that you installed basemap successfully "somewhere", but it might be that Spyder and Jupyter are installed in a different Python environment where you do not have basemap installed.

Using pyenv is perfectly normal on MacOs and GNU/Linux, I think it is an usual way to have Python installations. Also on Windows I use pyenv-win, which mimics the behaviour of pyenv but on Windows.

Unless you really know what you are doing, strongly recommend you install Python and Python packages with mamba/conda. You are mixing up versions - basemap has not been an mpl_toolkit for over 10 years. Mamba/conda are not perfect but they take most of the pain out of doing this sort of thing away, particularly for a package like basemap that depends on external C or FORTRAN libraries.

Hello again @molinav Yes actually appareantly it was installed within the pyenv folder, but i am not sure why, when I try to install it without opening an environrenmet with pyenv, it does not allow me. I attach a screenshot of what I get after typyin pip install basemap:

Is there a way to call the basemap installation or folders somehow to the python environment I created with conda ? sorry for my (maybe) obvious questions, i am a bit new on this stuff

[swiftienimbus]

hello @jklymak I tried to do that with conda actually, but i got errors since i think those libraries are depracted since years ago, that's why I tried with pyenv but somehow this is giving me more issues :/, I tried to create a new environment with conda with python 3.9 but I got the same message when I try to install basemap, that can't find packages compatible:

and then when i try to do it with pip install, somehow pyenv complains about it :/

[jklymak]

Sorry I guess I should have checked before posting. If I do:

 mamba create -n test basemap

I indeed get:

Encountered problems while solving:
 - package basemap-1.3.6-py311hf94de1b_1 requires basemap-data >=1.3.6,<2.0a0, but none of the providers can be installed

It looks like the recipe is not working on condo-forge.

[molinav]

For basemap, using conda or pyenv is a bit the same situation, because conda-forge does not have a basemap recipe for MacOS ARM64, and PyPI does not have MacOS ARM64 wheels, so in any case you need to build from source.

From your last tracebacks, your system seems to be quite messed up (your mamba/conda installation should also provide python and pip, but later pip is provided to you by the pyenv shims). I would suggest that you clean your system and either use conda or pyenv, but not both together.

[molinav]

@jklymak This is true, conda-forge still does not provide MacOS ARM64 packages (I tried to update the recipe but failed). For the PyPI wheels I simply did not have time to prepare the GitHub Actions.

Still, as long as @swiftienimbus has GEOS and a C compiler, it should be possible to install basemap from the sdist, either with:

python -m pip install basemap

in case that @swiftienimbus is using a system Python or pyenv Python, or with

python -m pip install --no-deps basemap

if using a conda installation, to avoid mixing pip and conda installations as much as possible. Still this would require that @swiftienimbus ensures the presence of the basemap requirements but installing them manually with conda install.

 mamba create -n test basemap

I indeed get:

It looks like the recipe is not working on condo-forge.

This is indeed unexpected behaviour, basemap 1.3.6 should depend on basemap-data >=1.3.2,<1.4, so maybe I have translated something incorrectly from the upstream basemap into the meta.yaml recipe file.

[jklymak]

Yes, I got it to work with:

mamba create -n test 
mamba activate test
mamba install matplotlib pyproj proj geos numpy
python -m pip install basemap

I think that doesn't require a working compiler, but I could be mistaken.

[molinav]

@jklymak The python -m pip install basemap will need a working C compiler in this specific situation because pip will not find MacOS ARM64 wheels, so it will pick the sdist and then it will try to compile the _geoslib.pyx wrapper extension. For Windows, GNU/Linux and MacOS x64 the C compiler is not needed, but for these architectures there is already conda packages for basemap anyway.

[molinav]

@jklymak On my Windows x64, basemap (1.3.7) and its dependency basemap-data (1.3.2) are resolved correctly for Python 3.11 (though I am using conda instead of mamba):

The python -m pip install basemap will need a working C compiler in this specific situation because pip will not find MacOS ARM64 wheels,

OK I have a c compiler, though I'm not sure at which step the c compiler was called ;-)

[swiftienimbus]

@molinav so I tried to do this to just work with conda: python -m pip install --no-deps basemap and almost everything works fine, but when I try to see if its working as is in your tutorial page i get this:

I tried to track what is missing in the init.py but i am not sure if i should modify this or not and I couldn't find the path to the mpl_toolkits , its a bit late here so maybe I am missing something ?:( thanks again !

[jklymak]

Did you do python -m pip install basemap-data?

[swiftienimbus]

python -m pip install --no-deps basemap

No, I tried in the main environment with

python -m pip install --no-deps basemap since i am working with conda there

[jklymak]

you need to install baseman-data, which you have not done because you are using --no-deps.

[molinav]

If you are working in the conda environment, python -m pip install --no-deps basemap will install you basemap but not its dependencies, due to the --no-deps switch.

After installing basemap, you need to install the basemap requirements one by one with conda install <the_dependency_here>. The list of requirements is here:

https://github.com/matplotlib/basemap/blob/v1.3.7/packages/basemap/requirements.txt

So in summary, you still need:

conda install basemap-data numpy matplotlib pyproj pyshp

[swiftienimbus]

Bravisimo! sorry for too much obvious questions, it was long time since I didn't install everything from scratch in mac, thank you so so much, now I am able to import it via Spyder as well !! I followed the whole steps (installing the missing packages you mentioned before via conda :D

[molinav]

Nice to hear that! Hopefully in the mid future I will add support for MacOS ARM64 and it will be less painful to install basemap. I am a bit behind because of not having a MacOS device to play around, but several MacOS ARM64 users have been struggling in the past due to the lack of wheels or conda packages, so it is really something that I should focus on in the future. Thanks to doing the same already for Windows and GNU/Linux, the installation on those systems is much much easier.

[efiring]

@ocefpaf, Is making a conda-forge recipe for basemap on MacOS ARM64 something you can help with?

[molinav]

@efiring @ocefpaf For your information, the main issue with the MacOS ARM64 pipeline in Azure is coming from the lack of MacOS ARM64 runners, so the conda package must be built through cross-compilation, and I always end up with "bad architecture type" error messages. The rest of the pipelines that use normal compilation (Windows, GNU/Linux and MacOS x64) are working fine.

[mpanning]

Any updates on getting conda-forge recipes for MacOS arm64? When I try to install via conda-forge, I get the error appended to this post. It's singularly uninformative, telling me that packages are incompatible with each other, and then not listing which packages are incompatible.

This is in a conda environment with Python 3.11. I have been able to install basemap from the anaconda channel in a python 3.10 environment, but that's causing me problems for a code with a basemap dependency for other reasons likely unrelated to this package. Regardless, it would be really handy if it worked on conda-forge again.

@mpanning Today I have finished updating the conda-forge recipe so that MacOS ARM64 is also supported. It would be great if you can give it a try. In my Mac mini M1 looks like below:

A simple test printing the basemap version in this environment:

(base) vic@alpha:~$ conda activate test311
(test311) vic@alpha:~$ python -c "from mpl_toolkits import basemap; print(basemap.__version__)"
1.3.9

I am not an expert on Miniforge/Anaconda, but while testing I realised that it is very important for basemap not to mix with other channels, i.e. to install basemap and all its dependencies from the conda-forge channel.

[molinav]

I am closing the issue, because with the upcoming release 1.4.0 (in a couple of days) I will be uploading MacOS wheels to PyPI manually, and since release 1.3.9 we already have MacOS arm64 packages in the conda-forge channel, so hopefully these installation issues on MacOS will become less common.

Feel free to reopen the issue if any of the problems persists.
