Arch Linux User Repository

You could install python-torchvision or python-torchvision-cuda from ArchLinux CN repo. I have no plan to provide two PKGBUILD for pytorch-torchvision and python-torchvision-cuda. However, pull request is welcome.

@hottea, I'm getting the same issue as @ioctl on the following tests after a full Arch update last night:

FAILED test/test_image.py::ImageTester::test_decode_image - AssertionError: False is not true
FAILED test/test_image.py::ImageTester::test_decode_jpeg - AssertionError: False is not true
FAILED test/test_image.py::ImageTester::test_encode_jpeg - AssertionError: False is not true

@ioctl You could build it in a clean chroot, and then report to upstream with full log.

@ioctl you could report bugs to upstream, not here. I usually skip the check.

I am not sure, they will accept it, because problem may be in Arch environment.

Anyway, if check periodically cause errors and you skip it in you own builds, may you remove it from the PKGBUILD?

@hottea Thx not only that, but it seems the problem was also in missing:

export CUDA_HOME=/opt/cuda

That fixed build error, i must say that was a looong build though :)

@keybreak you could skip the test.

Build currently fails for me, tested on Manjaro Stable

I also had the issue for the video IO test, uninstalling python-av and removing it from the makedepends solved the issue for me. I did not investigate further why exactly it is causing an issue

@bidskii You could skip the check, and report this issue to upstream, not here.
