Nearpoint You are not using the correct library (looking at DepthAI version: 2.22.0.0 ), after switching to rvc3_develop branch you also need to install correct library by executing examples/install_requirements.py.
Thanks, Erik

      depthai-sdk 1.13.1 requires depthai==2.22.0, but you have depthai 2.23.0.0 which is incompatible.

      which version of depthai-sdk will work with depthai 2.23.0.0

            I notice in the instruction it uses

            DepthAI version: 2.19.1.0.dev+c5fd7c993a3d446f6b9fdb54653cb49c7523534f

            But when I run python3 install_requirements.py I do not get that depthai version, in fact it just keeps whatever depthai version I already have

                Nearpoint

                How can I fix:

                Installing collected packages: depthai

                ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

                depthai-sdk 1.13.1 requires depthai==2.22.0, but you have depthai 2.22.0.0.dev0+acdd2024533cf8375db55c3d3137bf4ce750c54a which is incompatible.

                  erik

                  Ok so I deleted the python package cache, uninstalled depthai and depthai-sdk

                  I ran python3 install_requirements in the examples folder and everything installed successfully.

                  Still it is not recognizing the device here it the output:

                    But I still can not get the device to recognize. What do I do now?
