Tensorflow does not recognize GPU after installing CUDA toolkit and cuDNN

Question

I have a 1070 gtx. when I ran:

> sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

I got

This tells me tensorflow is not using GPU. I have installed CUDA 8.0, cuDNN 5.1, and tensorflow 1.1.0. I'm not sure what's wrong. Please help.

Answer 1

As @Alexander Yau pointed out, uninstalling the regular tensoflow package did the trick. Thanks.
