5 years ago ZED Explorer runs but the depth_sensing.py gives error ZED >> ERROR: sl::Camera::Open has not been called, no Camera instance running.
Also In Ros-wrapper, I am able to subscribe rgb images but for disparity or depth topics, the zed node crashes. Device: Tx2 sdk: 2.8.3 firmware:1523

5 years ago I had this error when launching ZEDfu in live mode : ZED >> ERROR: sl::Camera::Open has not been called, no Camera instance running. Solved it by using another USB 3.0 connector. The one in front wasn't working but when i plugged it at the back of the tower it worked !

5 years ago Solved it. I think the issue was log file generation space. While running zed camera, it requires 3gb of free space on tx2. When the error came, tx2 was having around 1.2gb space only.

4 years ago I have enough space on tx2 and the usb 3.0 hub works. I'm still facing this issue though.

4 years ago i receiving same error. I use
ZED_Depth_Viewer is running but API is not working.
Code :
import pyzed.sl as sl
zed = sl.Camera()
init_params = sl.InitParameters()
init_params.camera_resolution = sl.RESOLUTION.HD1080
init_params.camera_fps = 30
# Open the camera
err = zed.open(init_params)
if err != sl.ERROR_CODE.SUCCESS:
exit(-1)OUTPUT: [ZED]ERROR: sl::Camera::Open has not been called, no Camera instance running.

When I run the zed_cpp_sample,it has a error:ZED>>ERROR:sl::Camera::Open has not been called,no Camera instance running.I need help.Thank you!
