Different behavior of read_csv on Windows with Anaconda and Ubuntu 18
Hello, 

I'm experiencing different behavior of the following script:
https://stackoverflow.com/questions/57791115/forecast-produced-by-gluon-ts-example-is-around-0

on Windows with Anaconda and on Ubuntu 18. It works as expected on Windows, but doesn't on Ubuntu 18 (produces plot around 0)

This seems to have something to do with `df = pd.read_csv(url, header=0, index_col=0)`
