Hi is it possible to export model to "colorize.pb" format what can be used in ffmpeg dnn_processing filter https://ffmpeg.org/ffmpeg-filters.html#toc-dnn_005fprocessing-1 ? similar to this
./ffmpeg -i rain.jpg -vf format=rgb24,dnn_processing=dnn_backend=tensorflow:model=can.pb:input=x:output=y derain.jpg
