run_objectdetection can not be run successfully

[Programmerwyl]

The environment：jeston tx2:
opencv: 4.0.0
Camera: CSI Cameras
when I run run_objectdetection,it errors.

('frame', None)

Traceback (most recent call last):
File "run_objectdetection.py", line 189, in
detection(model, config)
File "run_objectdetection.py", line 84, in detection
gpu_feeds = {image_tensor: vs.expanded()}
File "/home/nvidia/Downloads/realtime_object_detection-master/rod/helper.py", line 220, in expanded
return np.expand_dims(cv2.cvtColor(self.frame, cv2.COLOR_BGR2RGB), axis=0)
cv2.error: OpenCV(4.0.0-pre) /home/nvidia/opencv/modules/imgproc/src/color.hpp:253: error: (-215:Assertion failed) VScn::contains(scn) && VDcn::contains(dcn) && VDepth::contains(depth) in function 'CvtHelper'

I find that "frame = vs.read()" is always None.
If you have any ideas,please tell me .
Thanks !

@Programmerwyl
are you using the current master?

1. how does your config look like?
2. Did you change code?
3. Which python / openCV /JetPack version are you using

[Programmerwyl]

@gustavz Thank you very much for your reply.
yes ,it is the current master
I haven't changed anything about your code.
python 2.7
opencv 4.0
jetpack 28.2

This is really strange as i just double checked everything today.
Which TensorFlow do you use?

I have the same problem, I'm using tensorflow1.6, opencv4.0, jetson Xavier.
Does anyone know how to fix it?
