What is the difference between tf.initialize_all_variables() and tf.initialize_local_variables()?

Question

I am reviewing the code in this example: fully_connected_reader.py

I am confused with Line 147 and 148:

init_op = tf.group(tf.initialize_all_variable         


        

Answer 1

• GLOBAL_VARIABLES

Key to collect Variable objects that are global (shared across machines). Default collection for all variables, except local ones.

• LOCAL_VARIABLES

Key to collect local variables that are local to the machine and are not saved/restored.
