ArduCam Stereo cameras won't work in Python #196

Hello, I would like to use the ArduCam Stereo HAT with two IMX 477 for depth mapping. With the following gstreamer pipe I get images fro the camera when running the pipe directly from the command line:

gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! 'video/x-raw(memory:NVMM),width=1920, height=1080, framerate=20/1, format=NV12' ! nvvidconv flip-method=0 ! 'video/x-raw,width=960, height=720' ! nvvidconv ! nvegltransform ! nveglglessink -e

If I use the sample Python program, I get the following error:

GST_ARGUS: Creating output stream CONSUMER: Waiting until producer is connected... GST_ARGUS: Available Sensor modes : GST_ARGUS: 4056 x 3040 FR = 10.000000 fps Duration = 100000000 ; Analog Gain range min 1.000000, max 22.250000; Exposure Range min 13000, max 683709000;

I'm pretty new to gstreamer, so any help would be very much appreciated. Thanks in advance.
