> I am now trying to run tensorflow on Autonlab, it seems I am always using CPU instead of GPU.  Then I try to add tf.device(???gnu:0???) in my code, then it shows that the GPU is not available. May I ask if you have any idea on this?<br>
><br>
<br>
I don't user TensorFlow but I know for the fact that it works as<br>
expected on all 7 GPU servers. You should have sent the e-mail to the<br>
mailing list so that you can get help from other TensorFlow users.<br>
