[python-torch-sparse] not build successfully

[nihil39]

Hi, I get this error while building python torch sparse 0.6.16-1

In file included from csrc/cpu/diag_cpu.cpp:3:
csrc/cpu/utils.h:4:10: fatal error: parallel_hashmap/phmap.h: No such file or directory
    4 | #include "parallel_hashmap/phmap.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~

error: command '/usr/bin/gcc' failed with exit code 1

ERROR Backend subprocess exited when trying to invoke build_wheel

 -> error making: python-torch-sparse

I'm trying to build this package as a dependency of pytorch geometric, a previous version of this package, now unmaintained can be found here

Thank you.

I think some dependencies should be added in the PKGBUILD, at least python gcc cuda cmake python-scipy python-setuptools python-pytest python-pytest-cov python-pytorch python-pytorch_scatter

[nihil39]

The error I got depends on the lack of this package: parallel-hashmap. Thanks to Lone Wolf of the Arch Linux forum, see this post

Please add parallel hashmap (and Pytorch?) as dependencies.

Nice finds.

@nihil39 do you want to give a go and writing a PR to try to resolve the issue? I can help you along the way!

[nihil39]

What is a PR? I think we have to modify the PKGBUILD to require parallel-hashmap and Pytorch as dependencies, maybe parallel-hashmap is only required as a build time dependency and not a runtime one.

So a PR stands for a pull request. It is how you can help me maintain and update the package.

See, by hosting my arch linux PKGBUILDs on github, not only can we comment easily like this via issues; but you can also make the fix to the PKGBUILD yourself and submit it as a change to this repo (PR). As you may know I maintain around hundreds of packages and I may not have time to give all the packages love, so my accepting PRs from the community (i.e. you) it makes my life (and everyone else that uses these packages) easier!

You can start by first forking this repository.

[nihil39]

So I should fork you repository, add the parallel-hashmap dependency to the python-torch-sparse PKGBUILD and make a pull request to you?

[acxz]

Exactly!
