Hi! I want to get more images which is png files in tests/image/imagenet but i don’t know how to get images.

I tried to use imagenet files but my files are JPEG files, so it doesn’t work with ./image-classifier.

thank you.

Hi, you should be able to convert the jpeg files to png pretty easily – e.g. you can try following directions here, or google for how to do so.

Thank you for answering me.

I tried to convert my JPEG file to png file by both ‘convert’ and 'mogrify command.
But when I execute the image-classifier, errors come again.

my command : ./bin_opt/image-classifier tests/images/i.png -image-mode=0to255 -m=inception_v2 -model-input-name=data “$@” -opencl -time -iterations=1

I don’t have enough info here to help debug… Can you compile in debug mode and run with a debugger, to try to print a more informative stack trace, e.g. with line numbers? Are you able to run with the test images that come with Glow (located at tests/images/imagenet/)?
