what's wrong with my demo.py ? about depthai_blazepose HOT 8 CLOSED

You get this error message when the device is not connected or connection is not ok. Check your connection. Have you been able to run other depthai demo like this one: https://docs.luxonis.com/en/latest/pages/tutorials/first_steps/#run-demo-script ?

from depthai_blazepose.

I have one webcam connected to my computer and it can work well with python open cv ,so it is strange to see that error

Have you followed the install requirements described there : https://docs.luxonis.com/en/latest/pages/tutorials/first_steps/#install-requirements (in particular if you are on linux, the commands in the Warning paragraph) ?

Do I have to use OAK-1 or OAK-D ? I now just use ordinary webcam for testing.

Sure, you have to :-)
Like it is said in the first line of the README:
Running Google Mediapipe single body pose tracking models on DepthAI hardware (OAK-1, OAK-D, ...).

I have another repo (with an older version of the models) that should run with your webcam: https://github.com/geaxgx/openvino_blazepose

thank you so much， but can you tell me the relationship between Mediapipe and blazepose ?and where I can buy the OAK-1 ?

You are welcome !
Mediapipe is an open-source framework from Google for building cross platform (Android, iOS, web,...) Machine Learning solutions. Mediapipe provides also a few dedicated models. Blazepose is one of them.
In this current repo, I just take the Blazepose model (without using the other parts of the Mediapipe framework). For this repo, the model has then been converted to run on the depthai framework, dedicated to the OAK devices. You can find all the information about the OAK-1 and other depthai devices there: https://docs.luxonis.com/projects/hardware/en/latest/
