[Tutor] Not able to import Tensorflow in python script

[shubham goyal]

Hello all,
I was trying to run this check script of tensorflow after installing the
tensorflow successfully. but it is not able to import tensorflow properly i
think. but sometimes in python
shell it gets imported. it is giving the error "can't import name template"

script

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


errors:
[0, 1, 2, 3, 4]
