Printing tensor values with tf.Print()

Another option to print values for debugging purposes is to use tf.Print(). You can wrap a tensor in tf.Print() to print its values in the standard error console when the path containing the tf.Print() node is executed. The tf.Print() function has the following signature:

tf.Print(     input_,     data,     message=None,     first_n=None,     summarize=None,     name=None    )

The arguments to this function are as follows:

• input_ is a tensor that gets returned from the function without anything being done to it
• data is the list of tensors that get printed
• message is a string that gets printed as a prefix to the printed output
• first_n represents the number of steps to print the output; if this value is negative then the value ...
