Issue in jpg_demo.py #5

Closed engrzeeshan closed 4 years ago

engrzeeshan commented 5 years ago

I'm running jpg_demo.py in Anaconda/Spyder on RHEL 7.5. I encounter following error:

CalledProcessError: Command 'gm convert lena1.jpg -quality 0 lena_tmp.jpg' returned non-zero exit status 127. <Figure size 576x576 with 0 Axes>

Please help me resolve the issue.

Have you solve the problem? I get the same issue, i don't know how to resolve it.

engrzeeshan commented 5 years ago

No, issue is not resolved yet. Do you know python code of image/video quality metrics?

sinianzaibeifang commented 5 years ago

I met a similar problem before.The system command 'gm convert...' in line 36 jpg_demo.py calls 'git merge' instead of 'graphicsmagick'.You can try to point out the path of 'gm'(graphicsmagick) in the code.

The jpg_demo.py has various erros of implentation. Use the Scikitvideo library in: http://www.scikit-video.org/stable/index.html

Please install graphicsmagick before running the demo, and make sure gm is in the path. This is not needed to use measure.py or to use the metrics from code.
