optic is installed using pip for Python 3. By default your local pip tool may be linked to Python 2. To be safe run the following command:
sudo pip3 install optic
If the pip3 command is not found install the package with:
sudo apt-get install python3-pip
Note that the above command will only work on Debian-based systems.
