pose_camera Buffer pool activation failed

Description

Hello,

I am new to this space, so I don't know too much about this error. I have been trying for a few days to get some of the posenet examples running. I am able to modify the simple pose example to take an image from the raspberry pi camera I am using, but I cannot run pose_camera.py without the error I'm attaching below.

I did have a few issues with other coral projects because I am using VNC, and I am NOT using the legacy raspberry Pi camera libraries. I am stubbornly using the new ones (Picamera2 instead of PiCamera).

I am having this same error with the object tracking using gstreamer: https://github.com/google-coral/example-object-tracker/tree/master/
