I have installed OAK-CM4-POE-V2 onto the sd card and inserted the card into rPI 4. I have OAK-D camera connected to the rPI. When I tried to run the mobileNet>rgb_mobilenet.py file, it gives following error.
(rgb:1373): Gtk-WARNING **: 15:54:42.785: cannot open display:
python: ../../libusb/os/threads_posix.h:58: usbi_mutex_destroy: Assertion
pthread_mutex_destroy(mutex) == 0' failed.pthread_mutex_lock(mutex) == 0' failed.
python: ../../libusb/os/threads_posix.h:46: usbi_mutex_lock: Assertion
How can I solve this issue?
