TensorFlow 1 version

Encode strings into web-safe base64 format.

Refer to the following article for more information on base64 format: Base64 strings may have padding with '=' at the end so that the encoded has length multiple of 4. See Padding section of the link above.

Web-safe means that the encoder uses - and _ instead of + and /.

input A Tensor of type string. Strings to be encoded.
pad An optional bool. Defaults to False. Bool whether padding is applied at the ends.
name A name for the operation (optional).
