Import error

I installed using pip, also cloned and used setup.py install but this error is still there:

this error is coming only for anaconda environment not for base linux python environment

Looks like a cvxpy issue. Have you tried to install it directly using their directions?

[purujitgoyal]

Installed cvxpy directly, still got the same error.

Mysterious! All I could find on Google is this:

This is likely not a fancyimpute issue. Sounds like something is up with the cvxpy install. Maybe try on their github page?
