I got this error while running the 01 intro file

[1030ahmad1030]

at the code cell:-Countries_mercator = countries.to_crs(epsg=3395) # or .to_crs({'init': 'epsg:3395'})
I had the following error.
RuntimeError: b'no arguments in initialization list'

That means that pyproj is not installed correctly

yeah, I downloaded only the zip file. could that be a problem as I dive deeper in the tutorial?
