We already did it [1] the repo provides all scripts to download the
data and run the training and also generates the header with weights
readily to use in ffmpeg.
When Jean-Baptist raised this issue we worked to provide all the
necessary scripts to perform training, reading the replies above, it
seems no one is  aware of it (not even J-B).
Isn't [1] enough? whats is missing then? why no one asked for whatever
may be missing in the original email when we provided the link to the
repo?
