faceit.py convert throws error if imagemagick not installed (if running GAN model)

[tauhlim]

Running faceit.py convert throws error if ImageMagick is not installed. moviepy states that ImageMagick is required for writing text, and more specifically is required for TextClip. Suggest updating requirements.txt or making text optional.

(tensorflow_p36) ubuntu@instance-1:~/GAN/faceit$ python3.6 faceit.py convert stark_to_hulk stark_suitup.mp4 --start 40 --duration 55 --side-by-side --use-gan --face-filter --width 800

OSError: MoviePy Error: creation of None failed because of the following error:

.This error can be due to the fact that ImageMagick is not installed on your computer, or (for Windows users) that you didn't specify the path to the ImageMagick binary in file conf.py, or that the path you specified is incorrect

Can verify that commenting out lines to add_caption avoid this error

        # Stack clips side by side
        if side_by_side:
            def add_caption(caption, clip):
                text = (TextClip(caption, font='Amiri-regular', color='white', fontsize=80).
                        margin(40).
                        set_duration(clip.duration).
                        on_color(color=(0,0,0), col_opacity=0.6))
                return CompositeVideoClip([clip, text])
            #video = add_caption("Original", video)
            #new_video = add_caption("Swapped", new_video)                
            final_video = clips_array([[video], [new_video]])
        else:
            final_video = new_video

Running command without
--side-by-side
option worked for me

python faceit.py convert fallon_to_oliver fallon_emmastone.mp4 --start 40 --duration 55
