Incompatible between Unity and python

[xlnwel]

I run obstacle tower on Ubuntu 18.04 and receive the following error messages

mlagents.envs.exception.UnityEnvironmentException: The API number is not compatible between Unity and python. Python API : API-10, Unity API : API-6.

But I've already install the latest mlagents. Here is a snippet of pip list

How can I fix it?
