Inference error on Jetson: failed to load image

Autonomous Machines Jetson & Embedded Systems Jetson TX2
1

I run according to the object detection demo at:
https://github.com/dusty-nv/jetson-inference#locating-object-coordinates-using-detectnet

I’m running detectnet-console on a network I trained on my host pc, and run it on an image that exists.
I had one good run. When I try to run again, it keeps failing with the error:
failed to load image.

Any idea why?

Thanks!

Hi zvika.peter, can you try changing your terminal’s working directory before launching the detectnet-console? Try this instead:

# after defining $NET environment variable to `~/DetectNet-COCO-Dog1-010818-1109-100epochs`
$ cd /home/nvidia/jetson-inference/build/aarch64/bin/
$ ./detectnet-console $NET/007414.jpg $NET/output007414.jpg --prototxt=$NET/deploy.prototxt --model=$NET/snapshot_iter_38600.caffemodel --input_blob=data --output_cvg=coverage --output_bbox=bboxes

Does that help?

Thanks duty_nv, but still not working…

Any more ideas why it cant find a file that exists?

I just tried with another file and it worked.
Have no idea why (the file is not corrupted and not open by the os)
Closing issue.
Thanks for the support!
