when I successfully install tensorflow on cluster, I immediately running mnist demo to check if it's going well, but here I came up with a problem. I don't know what is this all about, but it looks like the error is coming from CUDA

python3 -m tensorflow.models.image.mnist.convolutional

This was a nightmare to find a fix for - but the fix is somewhat simple

https://www.tensorflow.org/guide/using_gpu

# add to the top of your code under import tensorflow as tf
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
session = tf.Session(config=config....)
