Consistency checker makefile not found.

melon.mp4 is my filename
when I run this:

!python neural_style.py --video \
            --video_input_dir ./video_input/"melon.mp4" \
            --style_imgs starry-night.jpg \
            --content_weight 5 \
            --style_weight 1000 \
            --temporal_weight 1000 \
            --start_frame 1 \
            --end_frame 50 \
            --max_size 1024 \
            --first_frame_iterations 3000 \
            --verbose;

error occurs:

FileNotFoundError: [Errno 2] No such file: './video_input/melon.mp4/frame_0001.ppm'

then I run
!bash ./video_input/make-opt-flow.sh ./video_input/melon.mp4

error occurs again

Consistency checker makefile not found.

How to address it please?
