[gentoo-user] TensorFlow

[gentoo-user] TensorFlow

[Alan Grimes]

I wanna take a whack at an AI challenge,

https://www.aicrowd.com/challenges/unity-obstacle-tower-challenge

Ok, so I'm like
"emerge tensorflow"

It has been about two weeks since I've sync'd so this may or may not
still be valid, updating is an extremely risky operation on my machine
so I'm on a once every 3-6 months schedule...

current state:

#############
tortoise /home/atg/source # emerge tensorflow

These are the packages that would be merged, in order:

Calculating dependencies... done!

I've tried toggling the "test" flag on the package, no change. Would
trying to get Nvidia's containers working be a better way to waste my
time on this? Or should I give up and use google's cloud service? =\

what is risky about it at your machine?

You have at least three different ways to check for updates if you really 
can't upgrade on a regular basis:
1. sync your portage tree, but do not install updates (yet)
2. check online on gentoo.org or inside the mirror at github.com
   https://gitweb.gentoo.org/repo/gentoo.git/tree/sci-libs/tensorflow
3. check the packages page:
   https://packages.gentoo.org/packages/sci-libs/tensorflow

With regards to the persistence of bugs you should consult bugs.gentoo.org 
and search for your specific issue/bug.

I’m sorry I can't help with that linker problem, but at least I can say 
that tensorflow-1.13.0_rc1 built here without errors (and seems to run 
aswell).
But watch out, you need bazel-0.20.0 (see bug https://bugs.gentoo.org/
677280 for details).
