Tensorflow is a continuous pain to get working on any Linux other than a recent Ubuntu. Unfortunately most of my production systems are on some variant of CentOS 6…<\/p>\n
Here’s what I currently do to get Tensorflow 1.7.0 working on it. These instructions are brief and not absolutely step by step, but you can probably figure out what to do from them, and certainly I should be able to look back at these notes and figure out what I was doing. I’m not going to do things like explicitly tell you when to cd or mkdir a new place to drop things in. There aren’t proper patchfiles. These are scribbled notes as I went along getting bits from various links around the place.<\/p>\n
