UserWarning: This overload of add_ is deprecated

[josh-tegus]

Is it normal to get this trace back in the console? It spams for a few dozen times and then stops abruptly. Then, it starts logging the training session as intended. Sorry if this question is incredibly ignorant lol. I'm new to python and the world of ai. Figured I'd post my question here before searching Google. Thanks in advance.
