Troubleshooting¶

Camera Drivers¶

In case of a runtime exception, try use a smaller USB 3.0 cable.
In case you get the runtime_error:
```
Failed to access images from the camera.
```
try to disconnect and reconnect the camera first and see if that resolves the error. If it does not, then reduce the image width and height from the PylonViewerApp in /opt/pylon5/bin.
In case you get a numpy memory error while trying to access the stored images, or the error:
```
cv2.error: OpenCV(4.2.0) /io/opencv/modules/highgui/src/window.cpp:376:
error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'imshow'
```
while trying to view the image stream, reduce the image width and height from the PylonViewerApp. You can also try reducing the bandwidth in the Tools menu in the same app.
