See the guide: Control Flow > Debugging Operations

Prints a list of tensors.

This is an identity op (behaves like tf.identity) with the side effect of printing data when evaluating.

Note: This op prints to the standard error. It is not currently compatible with jupyter notebook (printing to the notebook server's output, not into the notebook).

Args:

• input_: A tensor passed through this op.
• data: A list of tensors to print out when op is evaluated.
• message: A string, prefix of the error message.
• first_n: Only log first_n number of times. Negative numbers log always; this is the default.
• summarize: Only print this many entries of each tensor. If None, then a maximum of 3 elements are printed per input tensor.
• name: A name for the operation (optional).

Returns:

A Tensor. Has the same type and contents as input_.
