BachBot

BachBot is a research project utilizing long short term memory (LSTMs) to generate Bach compositions.

Installation

Docker container images are hosted on DockerHub.

CPU-only

docker pull fliang/bachbot:base

CUDA-7.5

docker pull fliang/bachbot:CUDA-7.5

Getting Started

Set up environment

source scripts/activate

Prepare polyphonic Bach chorale corpus and train torch-rnn LSTM.

bachbot chorales prepare_poly && \
	bachbot concatenate_corpus scratch/*.utf && \
	bachbot make_h5 && \
	bachbot train

Sample the trained LSTM and decode output to musicXML.

bachbot sample <path_to_checkpoint> -t <temperature> && \
	bachbot decode decode_chord_constant_t_utf scratch/utf_to_txt.json scratch/sampled_<temperature>.utf

Workflow

• source ./scripts/activate.zsh to set up the working environment
  • Pro-tip: Add source ~/bachbot/scripts/activate to your .{bash|zsh}rc
• To develop on the scripts

  cd ./scripts
  pip install --editable .
  

  The bachbot shell command will use the entry point defined inside ./scripts/setup.py.
• To generate ctags which include system Python libraries

  ctags -R -f ./tags `python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"`<CR>
