GPU Sync Failed While using tensorflow

Question

I'm trying to run this simple code to test tensorflow

  from __future__ import print_function

    import tensorflow as tf

    a = tf.constant(2)
    b = tf.constant(3)


    with tf.Session() as sess:
        print("a=2, b=3")
        print("Addition with constants: %i" % sess.run(a+b))

But weirdly getting GPU sync failed error.

Traceback:

runfile('D:/tf_examples-master/untitled3.py', wdir='D:/tf_examples-master')
a=2, b=3
Traceback (most recent call last):

InternalError: GPU sync failed

Any help will be appreciated.

Answer 1

When I got this error GPU sync failed. Restarting my notebook/kernel did not help.

I had another notebook/kernel that was not shutdown and was using my GPU, so to fix this issue all I did was to shutdown the other notebook, restart my current notebook and everything worked!
