This article shows you how to create a calculation chart on the basis of TensorFlow. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

The following describes TensorFlow and several functions for creating a calculation graph:

G = tf.Graph () # create a new calculation graph g

G.as_default () # sets the calculation chart g to the currently used calculation chart

G0 = tf.get_default_graph () # get the default calculation chart

Tf.reset_default_graph () # clear the default calculation chart

Demonstration 1:

Import tensorflow as tf

# initialize a computed graph object g

G = tf.Graph ()

# add node definition calculation diagram to g

With g.as_default ():

A = tf.constant (10ther name ='a')

B = tf.constant (5 ~ name ='b')

C = tf.add (aPerm b)

Print (c.graph)

The output after execution is:

Demonstration 2:

Import tensorflow as tf

# get the default computed graph object handle G0

G0 = tf.get_default_graph ()

# add node definition calculation chart to G0

With g0.as_default ():

A = tf.constant (10ther name ='a')

B = tf.constant (5 ~ name ='b')

C = tf.add (aPerm b)

Print (c.graph)

The output after execution is:

Demonstration 3:

Import tensorflow as tf

# clear the default calculation chart

Tf.reset_default_graph ()

# nodes defined directly in Operator will be added to the default calculation diagram

A = tf.constant (10ther name ='a')

B = tf.constant (5 ~ name ='b')

C = tf.add (aPerm b)

Print (c.graph)

# View the Operators in the default calculation chart

Tf.get_default_graph () .get_operations ()

The output after execution is:

It is recommended to use demonstration 1 to define the calculation chart without having to tf.reset_default_graph () every time.
