multiple gpus not really working #29

Closed hughperkins closed 7 years ago

hughperkins commented 7 years ago

cannot seem to use CL_GPUOFFSET=1 to choose eg gpu 2
nor does using with tf.device('/gpu:1'): seem to work

hughperkins commented 7 years ago

CL_GPUOFFSET works now. Havent tested using gpu:1 much yet

hughperkins commented 7 years ago

CL_GPUOFFSET is all I'm using for now. Works ok :-) . Closing this for now.

Hello @hughperkins ,

This issue persists on my side. I'm using pre_compiled tensorflow-cl. Although I'm on macos mojave, it works most of the time only that switching GPU does not work...
