cannot load swan into python using recommended installation method

[smorabit]

Hi, first of all thank you for developing this wonderful software package! I am using a trying to use Swan on a 2019 MacBook Pro (Catalina), and I came across an issue while installing Swan.

I tried installing this package using pip install swan_vis as recommended, however I could not import the library into python. I actually had to use pip3 install swan_vis in order to get it to work properly.

Thanks,

Sam
