@gaborbernat please find package installed [root@localhost tests]# pip list DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. Package Version

Can you replicate this inside a Docker image? Seems again a virtualenv issue, but would need to investigate more to find the root cause.

@gaborbernat OK but as i am new to Docker, can you please let me know how can i replicate this in Docker Image ? Will like to dig more into it

[viraj1899]

@gaborbernat You may close the issue,as the issue if fixed. I have recreated the environment to run using python3.5 using tox -r py35 and set python=python3.5
