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) and found it was in an excellent condition.

@h-vetinari What is blocking this to be merged?

[h-vetinari]

Mainly the progress (or lack thereof, at least previously) of the abseil/grpc/protobuf migration. Since we now have to migrate per protobuf-patch version - and because it affects hard-to-rebuild feedstocks like pytorch and tensorflow - I tend to stagger the migrations a bit (recently also coupled with grpc to reduce the load, see conda-forge/conda-forge-pinning-feedstock#4075).

I was planning to do 4.24.x together with grpc 1.58, but I haven't fully debugged that build yet.

But if there's a need for the new protobuf (due to pertinent bugfixes etc.), we can merge this and migrate directly. IMO the existing migration has progressed far enough to close it.

For Tensorflow, currently, I feel like updating protobuf is the most likely path to succeed. I don't see a simple way to fix the mentioned protobuf+CUDA interactions.

[h-vetinari]

OK, let's merge this. I've done a bit of debugging for grpc 1.58, so we may be able to start the migration properly in any case.

[h-vetinari]

In any case, you can already pull this in for the tensorflow builds and "anticipate", the migration so to speak.

[xhochy]

MUST we do it together with grpc 1.58 or CAN we do it? I've seen some statements in the past, but my knowledge is not uptodate.

[h-vetinari]

It was necessary for the 4.x change, but we don't absolutely have to do it. It looks like 1.58 is only going to take a little bit more time though, so unless you need to start that migration in the next couple hours, we should still be able to couple them.

[xhochy]

Then let's do them together, Tensorflow is probably still 1-2 weeks away even if the migration helps. So there is no real time pressure.
