This is a Windows path error. You can the file missing file val3.txt in the folder data. And the script download_data should have copied val3.txt to the folder $KITTISEG/DATA/data_road/val3.txt (line 133).

Windows path notation (using \ instead of /) properly messed this up at some point. My guess would be, that you are able to fix this, by adjusting the paths in hypes/kittiseg.json to comply with Windows path notation (line 14).

Other then that, I would strongly recommend using Linux for deep learning ;).

Thank you

For windows users, please copy
$KITTISEG/DATA/val3.txt to $KITTISEG/DATA/data_road/val3.txt
$KITTISEG/DATA/testing.txt to $KITTISEG/DATA/data_road/testing.txt

Now both the demo and evaluate works fine ( Window 10 TensorFlow 1.0 cuda8.0 cudnn v5.1 python3.5)

• python demo.py --input_image data/demo/demo.png
• python evaluate.py
