when i check for psychtoolbox  
`pip install psychtoolbox`

i see the following output

```auto
Requirement already satisfied: psychtoolbox in /opt/anaconda3/lib/python3.9/site-packages (3.0.18.2)

Requirement already satisfied: numpy>=1.7 in /opt/anaconda3/lib/python3.9/site-packages (from psychtoolbox) (1.20.3)

```

any help to get me started would be greatly appreciated.
