hello,

im trying to get get a camera working on my jetson nano, waveshare jetracer pro using the B02 board,

heres my code: #creating camera class

from jetcam.csi_camera import CSICamera camera = CSICamera(width=224, height=224, capture_fps=65)

here is my full error output:

RuntimeError Traceback (most recent call last) /usr/local/lib/python3.6/dist-packages/jetcam-0.0.0-py3.6.egg/jetcam/csi_camera.py in init(self, *args, **kwargs) 23 if not re: —> 24 raise RuntimeError(‘Could not read image from camera.’) 25 except:

RuntimeError: Could not read image from camera.

During handling of the above exception, another exception occurred:

RuntimeError Traceback (most recent call last) in 1 from jetcam.csi_camera import CSICamera 2 ----> 3 camera = CSICamera(width=224, height=224, capture_fps=65)

/usr/local/lib/python3.6/dist-packages/jetcam-0.0.0-py3.6.egg/jetcam/csi_camera.py in init(self, *args, **kwargs) 25 except: 26 raise RuntimeError( —> 27 ‘Could not initialize camera. Please see error trace.’) 28 29 atexit.register(self.cap.release)

RuntimeError: Could not initialize camera. Please see error trace.

Hi, I'm having the same error in a different project (DLI Getting Started with AI Course) and haven't solved it with the methods I find on NVIDIA. Did you solve it in your case?

Out of curiosity, do you have "jetcam-0.0.0-py3.6.egg/jetcam/csi_camera.py" located in /usr/local/lib/python3.6/dist-packages/? I don't and I wonder if it's related to the error. Hope I'm allowed to ask here!

there is a camera reset service that should do the trick but didnt work for me, https://github.com/NVIDIA-AI-IOT/jetracer/blob/master/notebooks/reset_camera_service.ipynb my solution which didnt fix the problem but is a work around, is to restart the jetson nano. here is another solution you can try, https://github.com/NVIDIA-AI-IOT/jetracer/issues/104
