Hello, dears:

    Recently I have met an issue, Could you help me?

    I run pycharm app on my Win 10 and python interpreter on remote docker container on centos 7.

    when I add python interpreter on pycharm, I have met an error "repository docker.io/pycharm_helpers not found: does not exist or no pull access".

     pycharm version: 2018.1.4 professin, docker version: 1.13.1, python in docker version: 2.7.15.
