Checklist

  • Used a personal fork of the feedstock to propose changes
  • Bumped the build number (if the version is unchanged)
  • Reset the build number to 0 (if the version changed)
  • Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
  • Ensured the license file is being packaged.

Some minor fixes from #409, as they apparently aren't causing the problems there; plus fix for the migrator to make conda smithy rerender work again.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

  • ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
  • ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

This message was generated by GitHub Actions workflow run https://github.com/conda-forge/conda-forge-webservices/actions/runs/17515479186. Examine the logs at this URL for more detail.

I guess we're seeing an xdist regression here? Or perhaps a new pytest/xdist version triggering an existing test suite problem?

Okay, so the first set of failures were regression with pytest-rerunfailures==16.0 (already removed from conda-forge).

Now I'm seeing the same failures as in 2.8.0 bump, so I guess they're not regressions in PyTorch itself.

@conda-forge/pytorch-cpu, should I add these tests to skip list?

I don't think we should be skipping segfaults

BTW, I'm quite surprised that windows is passing here and that the errors are on linux only; #407 suggested it's the other way around on 2.7... 🤔

Oh, I didn't notice that. Damn.

I guess I need to find the last passing 2.7.1 build and start diffing. The problem is, I couldn't reproduce the problem locally with 2.8.0, so I suspect here I won't be able to either. I somewhat suspect it might be CUDA runtime or something.

Might be worth trying if going back to CUDA 12.8 fixes things. We already had to do that on windows as well (for an almost certainly unrelated reason, but still).

Yeah, I'll try this for now.

For the record, last successful build was at: https://github.com/conda-forge/pytorch-cpu-feedstock/actions/runs/16611213618/job/46994510468

To compare with: https://github.com/conda-forge/pytorch-cpu-feedstock/actions/runs/17378832875/job/49331279402?pr=411

Unfortuantely, the diff in package plan is pretty large.

Unfortunately, that wasn't it. I'll revert to 12.9 and start looking at the diff.

My best guess right now is cudnn, cusparseLt, nvtx-c, or rdma-core. These packages are specific to CUDA build, not pinned to major CUDA version, and had new versions between the last successful build and now. I'll try pinning all four and see what happens.

…5.09.04.02.19.31

Other tools:
- conda-build 25.7.0
- rattler-build 0.47.0
- rattler-build-conda-compat 1.4.6

Yeah, sorry about the noise. I really didn't expect it to take this long.

On the contrary, thanks so much for digging into this! 🙏 ❤️

Finally a successful test run (it failed later for irrelevant reasons).

Now to figure out which of the test environment changes is causing the segfaults…

So need to take a look at the diff between:

last bad test run here: https://github.com/conda-forge/pytorch-cpu-feedstock/actions/runs/17559445803/job/49871849794

and the good test run here: https://github.com/conda-forge/pytorch-cpu-feedstock/actions/runs/17693457748/job/50290037339

I'm going to try playing with the artifacts a bit, hopefully reproducing it without having to keep triggering CI.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

  • ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
  • ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

This message was generated by GitHub Actions workflow run https://github.com/conda-forge/conda-forge-webservices/actions/runs/17720864211. Examine the logs at this URL for more detail.

This thing truly hates me.

So far I'm 90% convinced cudnn was the problem after all (but I failed to pin run dependency initially), but now I'm hitting some weird CMake failure. I'll investigate it later today, if nobody beats me to it.

Uh, that CUDA change is going to be a pain, since it affects everything pinned to CMake < 4, I guess.

This reverts commit ee2ad2a.
This solves only immediate build, doesn't solve revdeps or tests.

It worked! I think keeping the history here is valuable, but adding all the changes to main is not, so I'll close this PR and merge the relevant fixes to the 2.8.0 bump, and see how it goes.

Uh, I forgot that 2.8.0 run out of space on Windows. Nevertheless, let's try again. Worst case, I'll open another backport to 2.7.1.
