Hi zivp ,
Sorry about the trouble. So this is one of the few experiments we haven't yet ported from our Gen1 API to our Gen2 API.
So before you try to run the example, it is necessary to first run the following command in the social-distancing folder:
python3 -m pip install -r requirements.txt
We actually do this for all examples, we force them to be tied to a specific DepthAI API.
So yes, it is the DepthAI 184.108.40.206 problem - this example uses the Gen1 API (0.4 in this case).
Sorry again about the trouble.
