DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use `array.size > 0` to check that an array is not empty

Hey guys, I am getting this deprecation warning when I am running dialogue_management_model.py.

“DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use array.size > 0 to check that an array is not empty.”

Please help me to understand this warning.

What exactly are you doing? If you search for the error, you will find a couple of explanations, e.g. python - sklearn DeprecationWarning truth value of an array - Stack Overflow
