GStreamer Error Jetpack 4.5 Dusty-Nv imagenet.py

Hey I want to check if this is a JP 4.5 issue before I flash back to 4.4 as suggested elsewhere. I was attempting to run imagenet on a classification model I quickly re-trained but even though I am feeding it images and not using camera, it fails to load because there is no camera…

error:

  error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:645 No cameras available
  [gstreamer] gstCamera -- end of stream (EOS)

Thanks!

Hi @tom.parkerete4t, which camera are you using?

If it’s a MIPI CSI camera, are you able to see the image stream with nvgstcapture-1.0?

I am not using a camera, none plugged in, I am giving it images as input.

I just ran nvgstcapture and this was the output, same problem (this time I plugged in my webcam which has worked with jetson before, just to test it, it is a C220)

Output:

Oh, I see, sorry I misunderstood I thought you were trying to use camera. Can you try running it like this:

python3 imagenet.py --model=test_001.onnx --labels=testlabels.txt --input_blob=input_0 --output_blob=output_0 "test_images/*.jpg" test_results/result_%i.jpg
