Problem with installation on linux/arm64 conda environment #581

leonid-butenko · 2023-07-20T13:48:15Z

Hi,

I'm trying to install basemap on my mac using docker. As long as conda-forge doesn't seem to support basemap for linux-aarch64 architecture, i try to do that with pip. What am I doing wrong? Running basemap build manually gives same result

> docker run -it --rm --platform=linux/arm64 condaforge/miniforge3:latest

Hi @leonid-butenko! Sorry for the late reply. I can reproduce the same problem as you on my Windows machine. It seems that it is being caused by the latest release 3.0.0 of Cython. I will downgrade the Cython upper pin from "< 3.1.0" to "< 3.0.0" until this Cython major release becomes more stable.

molinav · 2023-07-22T16:13:37Z

@leonid-butenko May I ask you to try two things on your system? After configuring GEOS_DIR properly:

First, try to install basemap version 1.3.7 from the GitHub repo with the command below, which should fail with the same error as in your original issue:

python -m pip install git+https://github.com/matplotlib/[email protected]#subdirectory=packages/basemap

Second, try to install basemap hotfix branch 1.3.8 with the command below, which (hopefully) would work:

python -m pip install git+https://github.com/matplotlib/[email protected]#subdirectory=packages/basemap

If both installation cases are reproducible for you (that v1.3.7 fails and hotfix-1.3.8 works), then I can confirm that the source of conflict is Cython 3.0.0, and I can try to prepare the v1.3.8 release in a few days.

molinav · 2023-07-24T18:00:17Z

@leonid-butenko It would be great if you can provide your feedback during this week, then I can prepare the 1.3.8 patch release including this bugfix soon. Very likely the issue is with the Cython 3.0.0 version, since I could reproduce the same error as you and it is gone after pinning Cython to the 0.29.x series, but before releasing I would like to confirm that the problem also gets solved for you.

leonid-butenko · 2023-07-24T20:59:15Z

@molinav Thanks for your quick reply! Something strange here. As you suggested the first command with installation from GitHub fails exactly the same way as before. Howerer the second one has another issue. During building it complains about linking errors. Please see below:

I thought ok, may be it's a broken geos lib coming from conda. Then I skipped geos from the list in the commands sequence above and installed it manually from source code as suggested in here https://matplotlib.org/basemap/users/installing.html.
Surprisingly pip install did eventually work:

Apparently the _geoslib.cpython is not there. Any ideas?

molinav · 2023-07-24T21:31:10Z

@leonid-butenko Thanks for the feedback! Now I am a bit confused, but very likely due to lack of knowledge:

Your container has platform linux/arm64. However, I see that the compiler is /opt/conda/bin/x86_64-conda-linux-gnu-cc (so x64 compiler). Is this a normal thing in conda for ARM64 and the compilation is by default cross-compilation?
I would also wonder if the conda shared library libgeos_c.so is compiled for ARM64 or for x64. Non-matching architectures could be a reason why the traceback says that the shared library is incompatible.
It is strange that the file _geoslib.cpython-310-aarch64-linux-gnu.so is not available at site-packages, because it gets bundled automatically into the wheel when building without having to do anything manually. You can try to rescue the built wheel file and check that the _geoslib.cpython-310-aarch64-linux-gnu.so is actually missing there.

Unfortunately I have no ARM64 machine around, so it is not easy for me to test locally. However, at least the original error opening the issue seems gone, and it was caused by Cython 3.0.0 (I have found other projects affected in the same manner). At some point I will need to update the _geoslib.pyx file to make it compliant with Cython 3.0.0.

leonid-butenko · 2023-07-25T05:45:41Z

Sorry, my fault. Thanks for spotting that. Indeed I used amd64 version of the compiler in my last experiment. Here is the right one. And it seems to work:

btw, you can easily run mac (arm64) docker images in emulation using QEmu, they are much slower on intel but that's enough for testing. If you have qemu already installed, just run the docker command from my post.

Nice to see that it is working! If you think the problem is solved, then feel free to close the issue.

In the end your second problem here is more the lack of conda packages for linux/aarch64. This target and osx/arm64 are both missing in the basemap-feedstock. I tried a while ago to extend the recipe for osx/arm64, but I had no success due to cross-compilation issues. But of course if these conda packages were available, it would be for you as easy as doing conda install basemap, and you would not need to do the manual compilation of basemap.

Let's see if I find time in the future to play around again with the basemap-feedstock recipe.

Sure things. Thanks for your support!

@leonid-butenko Today I released basemap 1.4.0 together with the corresponding packages for conda-forge, and I took some time to migrate the feedstock so that basemap also has conda-forge packages for linux/aarch64. Feel free to try them!
