Hi,

If I try to import Earth I get this error:

Any suggestion?

Hello,

do you have scipy installed ? in case you don't, it should work after a "pip install scipy" or "conda install scipy" in case you have anaconda.

In addition to making sure you have scipy, you should also check that your scipy version is at least 0.16.0.

I'm closing this because I suspect it was just an issue with installing scipy. @LorenzoBottaccioli if you're still having problems please comment or reopen.
