Musescore plugin works, but cannot compose

[hans-ekbrand]

I have got the Musescore plugin to work, it can list models and load a model, but when I select a section of a four part chorale and press "Compose", the server fails with the following error:

[2018-02-22 18:58:03,513] ERROR in app: Exception on /compose [POST]

I have the same problem

I don't have an answer for you, but one possible cause is Python version. I see you are running Python 2.7, while DeepBach uses Python 3.6. I'm not an expert, but from painful experience it's safe to assume that 3.X code will not work with 2.X compiler and libraries.

In other words, you should probably completely re-install DeepBach, but first you need to install Python 3.6 and libraries. Myself, I use the Anaconda distribution and conda library/package manager.
