Sorry TeeFix42 for the trouble here (and the delay in response).
So we have seen in other cases that models that fail to compile in 2020.1 actually work fine in newer versions, like 2021.2. A recent example is here actually.
So I'd recommend giving 2021.2 a shot. So on that, as you I think already know, our Gen1 API is actually set on 2020.1. But our Gen2 API (which we intend to formally release this month to replace Gen1) supports all OpenVINO versions. It simply auto-detects which version was used to compile the model.
The Gen2 API is more flexible, so instead of doing one demo program (like we did in Gen1: depthai_demo.py), we instead have a slew of simpler examples along with examples of more complicated multi-stage flows.
Below is one basic example:
And there are more complicated examples here:
So anyway, try OpenVINO 2021.2 and see if the problem goes away. If it does not, let's involve PINTO0309 in our Discord as he'll likely be able to make it work.
