How to handle FFMPEG module missing probe inside docker?

I am AWARE of how to solve this problem of missing problem module with spleeter on WINDOWS. Here is the solution WARNING:spleeter:module 'ffmpeg' has no attribute 'probe' · Issue #101 · deezer/spleeter · GitHub

How can I achieve the same inside my docker container? In my docker file, the FFMPEG is being installed but it is missing the probe module. This is a common problem but one that I don’t know how to solve inside of Docker.

I tried doing

RUN apt-get install -y ffmpeg
RUN pip uninstall ffmpeg-python
RUN pip install -r requirements.txt

in my docker file but didn’t work. The thing is, it was all working until last night. Today morning, I am getting this error when I rebuilt my docker image. Any help is appreciated.
