The functions in sub and mul in the official TensorFlow document have been renamed in the API

The following two issues were encountered in TensorFlow Chinese document Learning TensorFlow in TensorFlow official documents and Geek College:

1) attributeerror:module ' TensorFlow ' has no attribute ' sub '

# Enter an interactive tensorflow session Import  == tf. Variable ([1.0,2.0= tf.constant ([3.0,3.0])# initializes ' x ' with the Run () method of the initializer Initalizer op X.initializer.run () # Add a Subtraction sub op, subtract ' a ' from ' X ', run minus op, output sub = tf.sub (x,a)print(Sub.eval () ) # task complete, close reply Sess.close ()

Executive Times Error:

Traceback (most recent):   " c:/pythonproj/tensorflow/first_tensorflow.py "  in <module>    ='tensorflow '  Sub'

After the pycharm in the TF. Auto-echo information, I found that this sub function has been replaced by subtract, replaced by Tf.subtract (x,a), OK, all smooth!

2) Attributeerror:module ' TensorFlow ' has no attribute ' mul '

INPUT1 = tf.constant (3.0= tf.constant (2.0= tf.constant (5.0== Tf.mul (INPUT1, intermed) with TF. Session () as sess:    = Sess.run ([mul,intermed])    print(Result)

The error message is:

Traceback (most recent):   " c:/pythonproj/tensorflow/first_tensorflow.py "  in <module>    ='tensorflow '  Mul'

In the same vein, after the observation of the pycharm in TF, I found that the Tf.mul function has been replaced by tf.multiply, modified, ok!
