Your kernel may have been built without NUMA support.

I have Jetson TX2, python 2.7, Tensorflow 1.5, CUDA 9.0

Tensorflow seems to be working but everytime, I run the program, I get this warning:

with tf.Session() as sess:
… print (,feed_dict))

Should I be worried ? Or is it something negligible ?
