Trouble with cvxpy

[rukawa917]

I seem to have error in importing cvxpy for some reason.

I have looked for solutions, but I can't find the solution. Below is the error I got.
I am using PyCharm and my OS is Mac.

Traceback (most recent call last):

Please help

Hey there!

Looking at the traceback I think this issue has to do with incorrect installation of cvxpylayers and more specifically it's dependency diffcp.

I would image that if you try to run the following import inside of Python you get the same error, right?

import diffcp.cones as cone_lib

Anyway, if that is the case, I would definitely encourage you to read through issues in the following repos. And if none of them addresses your problem you should probably create a new issue.

• https://github.com/cvxgrp/cvxpylayers/blob/master/setup.py
• https://github.com/cvxgrp/diffcp

If you figure out the problem, feel free to close this issue and potential describe what measures you took:)
