[SOLVED] Tensorflow: failure occurred in build()

Using yaourt to install tensorflow, fails to build. Any input would be appreciated on the following question:

1. Why is the build failing?

2. Is there another way to download Tensorflow? I'm not very familiar with installing from github.

python-tensorflow-git 0.10.0.r1362.g4addf4b-1  (2016-09-15 07:22)

Re: [SOLVED] Tensorflow: failure occurred in build()

Check the package comments when you have AUR errors - it is particularly odd that you didn't see them, as yaourt spits them all out at you as it builds: the comments include this error and the solution.

Trilby, really stupid of me to not check the comments. I'll get back after trying the solutions there.

Re: [SOLVED] Tensorflow: failure occurred in build()

In answer to your question 2, I install with pip which avoids a bunch of compiling (including having to first build bazel). Instructions available on the tensorflow website.

Edit: of course you might still want to use the AUR version as then yaoart keeps track of dependencies/upgrades for you.

AUR comments didn't solve my problem but the pip install worked. Thanks for the link.
