tensorflow CUDA_ERROR_UNKNOWN error

I downloaded CUDA Toolkit 8.0 GA2, cuDNN v6.0 for CUDA 8 and tensorflow 1.4. I have an Nvidia 740M graphics chip. I tried running this code to test tensorflow:

import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

This is what it returns:

2017-11-09 16:25:42.999638: I C:\tf_jenkins\home\workspace\rel-win\M\windows-gpu\PY\36\tensorflow\core\platform\cpu_feature_guard.cc:137] Your CPU supports instructions that this TensorFlow binary was not compil

b'Hello, TensorFlow!'

What does the error CUDA_ERROR_UNKNOWN mean? How do I fix it? Thanks

Updating the graphics driver fixed it.
