tensorflow debian package
OK. tensorflow made it to the top of my list. Sadly not in time for
the upcoming stable, but well, that's life.
So. I just tried building what is in https://salsa.debian.org/deeplearning-team/tensorflow
One odd thing: the 2.3.1 that is in the pristine-tar branch does not exist as a tag upstream:
https://github.com/tensorflow/tensorflow/tags
they have 2.2.2 and 2.3.2.
That's the upstream in the watch. Did you get 2.3.1 from somewhere else?
I have a couple of general questions to start with:
1) What is the expected build/packaging workflow? I couldn't see a
README that said. It seems that 'gbp buildpackage' is the rune to
generate an orig tarball and start a build, but it's not clear if I
should just commit things (in which case dpkg-source complains about
changes) or use quilt in the usual way and commit patches? I'm used to
either quilt-with-no-git or git-debrebase 'autogenerate the patches'
workflows.
(Hmm, the bazel manpage claims to have 'info' documentation, which
seems surprising, and is of course wrong :-)
Is there a clean way to do a 2nd build with gbp? It complains about a
changed repo, and indeed all the stuff which was patched by the debian
patches is indeed changed, so I need to do a 'dpkg-source
--after-build .' to unapply the patches so the repo is clean before
doing gbp buildpackage. (why doesn't gbp buildpackage set up its build
state, the way the dpkg-buildpackage does? Perhaps I am using the
wrong tools here?)
OK. It looks like I should commit patches (a-la dpkg-source --commit)
and use dpkg-buildpackage (and commit the patches to git). Then
everything seems happy. That's fine by me. After removing the
--noincompatible_prohibit_aapt1 option which seems to be specific to
bazel2 I get a build going.
It builds for 20mins, doing 1400 jobs, but gives an error:

I can look into that.
I should really ask you the more general question:
2) What still needs doing to make this package ready for debian?
I see that tensorflow-lite is not yet packaged and that is the part
that I am most interested in, so I'd better work out how to do that, once I've got it building at all.
