No open-cl documentation

Very confused. How does one install and test this? It's basically just a big old directory with lots of files and the readme is just a copy of the tensorflow install which tell you how to install tensorflow, not tensorflow-opencl.

Thanks for you interest. Please take a look at the OpenCL specific section of the overall documentation. This will be published on the tensorflow.org site soon.

Hello,
Thanks. Will wait for you guys to official open it up on tensorflow.org site. I hope intel gpus are supported as the documentation under the opencl specific section only talks about AMD

I looked there. I get a bunch of errors when running configure for tensorflow, like this:
ERROR: /home/ben/tensorflow-opencl-master/tensorflow/workspace.bzl:17:3: //external:eigen_archive: no such attribute 'urls' in 'new_http_archive' rule. Ok, I resolved this. It's a known bug in bazel tensorflow/tensorflow#6436

atlury, any gpu which has drivers that support OpenCL 1.2 will work with this tensorflow-opencl. I'm currently testing it on AMD APU called Kaveri A10-7850K, aka STEAMROLLER!!!!!!!

anyway, I got it to compile and install via pip3. Thank you for all of this. One more thing I think needs to be clarified is --copt=-march=native. This is supposed to optimize tensorflow to take advantage of my CPU features. But I can't find a list of those optimizations. Is there a file which lists all of these?
Found a list of gcc options here: https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html
On a AMD A10-7850k the one that worked and compiled was bdver3

Is this going to be merged with the main tensorflow project at some point?
