Thanks but I already tried this and it does not work.
The error is : [Errno 2] No such file or directory: ‘ffmpeg’.
And also from the container terminal ffmpeg is missing, that is why I thought it should be added to the docker file, and I listed my attempts.
Maybe it should be compiled from source?
This shows that the package can be simply installed without any extra system dependencies. It should also work if you add it to your docker file and create a new docker image on top of the one from eo-learn.
It turned out the problem was that self.out_dir didn’t exist. So I had to add a line:
before the problematic line. Then it successfully created a video and a gif.
Overall, the notebooks that are just in the eo-learn repository but not used for the official documentation are not that frequently maintained and can have such minor reproducibility issues. Thank you for pointing out this issue.
