[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:

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? =\
