Hello @cogrow4
I have some questions regarding the Dockerfile.
You copy the entire swingmusic source code into the workdir.
Could you please explain why you changed from the old wheel install to a source install?

Oh sorry, I forgot to change it back to wheel after I was testing some builds. I just had some issues with wheel locally. I can just change the dockerfile back.

Could you please state which issues you encountered when using the wheels locally.
