tensorflow Variable Initialization error : Attempting to use uninitialized value Variable

Question

Why is this happening? Error message - Attempting to uninitialized Variable Error here is my source: source - Learning .JPG Image in computer using tensorflow

I don't know why this error occur... I already used two types of variable initialization function:

1. tf.global_variables_initializer()
2. tf.local_variables_initializer()

  sess.run(tf.global_variables_initializer())
