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!
LevineYang commented
Same problem, did you figure it out?

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

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 !
Deleted user commented
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.

I have enough space on tx2 and the usb 3.0 hub works. I'm still facing this issue though.
tlhcelik commented
i receiving same error.
I use
- Xavier AGX
- R32.3.1
- CUDA10.0
- 500 GB NVMe Disk
- OpenCV 4.1.1
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.
