#DOWNLOAD VIRTUAL ENV
sudo pip install virtualenv


#CREATE FOLDER
mkdir -p python3_ws/src

#GET INTO FOLDER
cd python3_ws

#CREATE ENVIRONMENT
virtualenv py3venv --python=python3

#ACTIVATE ENVIRONMENT
source ~/python3_ws/py3venv/bin/activate


#ALL PYTHON3 LIBRARIES AND DEPENDENCIES MUST GO INSIDE python_ws/src
cd ~/python3_ws/src

#STEP 1:OPENAI
