Hi Sarah - From the Python error, it looks like you're mixing Python 3 code with a Python 2 executable. Since you don't list your actual commands issued, I can't tell. If you have both installed and don't know if you need Py2, I'd say to try removing it & see what happens for a day. Hope this helps! - MLD
