Install ml-agents in ubuntu

Hi everybody, i have ubuntu 18.04 and I want to install unity and ml-agents per hobby. I read the github documentation but I do not know what I do wrong because after doing the steps the ml-agents are not executed. I have installed ml-agents, unity and tensorflow but I do not know if it is properly installed. Someone can help me?

  1. I’m downloaded Unity from this web and execute the file for install.

  2. Later i download the ml agents with git clone

  3. cd ./ml-agents/ml-agents

  4. pip install -e.
