depthai_class ... takes 2 positional arguments but 3 were given.

Hi All, I was testing social-distancing example and try to run main.py (either with DEBUG ON/OFF), I got the errors as shown below.

Can anyone help to fix the error ? Thanks.

Hi demoacct01 ,

Sorry about the trouble here. Let me try to reproduce it.

Prior to that, I wanted to double check, did you run python3 -m pip install -r requirements.txt in your virtual environment prior to running python3 main.py?

The reason I ask is this looks like a versioning issue between the library expected by the example, and the library installed/used in the virtual environment.

The python3 -m pip install -r requirements.txt command installs what should be the correct depthai library for the example, such that if we ever change the library, and forget to update an example, the example will still work. (And then we try at best effort to go through and update examples over time.)

Thoughts?

Thanks,
Brandon

Hi demoacct01

I was able to reproduce this. Something is definitely wrong with this example. I wonder if when we shrinking our Github we messed up commit-linking from this repository.

Anyway, I get the same error:

Will circle back soon.

Brandon Thanks for checking. Will wait for your solution. Cheers. ;-)

Hi demoacct01

This should now be working. It properly works for me now. https://github.com/luxonis/depthai-experiments/tree/master/social-distancing

Do a git pull and don't forget to run python3 -m pip install -r requirements.txt.

I'm asking the team what had gone wrong to cause the demo to stop working.

Brandon

Thanks @demoacct01 ,

We will have this fixed today. Will circle back with description of the fix as well, and what caused this error to happen.

Thanks,
Brandon

Hi Brandon tested and it is working properly now. Thanks.

Meanwhile I have started to experiment with the various examples found in "depthai-experiment". ;-)

Brandon

Great thanks for the followup.
