Pyfolio Import Error

Question

When I simply just import pyfolio, I found this error. I've searched on internet, I found some posts saying it's the API issue BTW data provider and pandas(never able to get yahoo data anyway). However, I couldn't find a way to solve it. Is there anyone can help me with this please?

Thanks a lot for your time.

My version of pandas and pyfolio is below:

pyfolio(0.8.0)
pandas(0.20.3)
pandas-datareader(0.3.0.post0)

import pyfolio

Traceback (most recent call last):

Seems to be issue with PyFolio release.

Look at similar issue at GitHub.

Install latest version from clone of GitHub repository , that should solve the issue otherwise you need to open a issue at GitHub.

There are similar issues about Yahoo URL failures on the site.

You seem to have old version of pandas-datareader latest version is 0.6.0 as of today. And please see that Yahoo API has been deprecated lately

Warning

As of v0.6.0 Yahoo!, Google Options, Google Quotes and EDGAR have been immediately deprecated due to large changes in their API and no stable replacement.
