NameError: name 'GaussianPolicy' is not defined

Where do you define the GaussianPolicy function described in main.py line 138? NameError: name 'GaussianPolicy' is not defined

I couldn't find the function in any of the .py files inside the core folder or main.py itself. So, if it's from another library, to which one does it belong? Searching online I could only find a GaussianPolicy from TensorFlow: see here But that doesn't seem to be the correct one either.
