Looking around

• code: the main codebase (a Python package called groove2groove)
• data: scripts needed to prepare the datasets
• experiments: experiment configuration files
• experiments/eval: evaluation code (see the eval.ipynb notebook)
• api: an API server for the web demo

Installation

Clone the repository, then run the following commands.

1. Install the dependencies using one of the following options:

   • Create a new environment using conda:

     conda env create -f environment.yml
     

     This will also install the correct versions of Python and the CUDA and CuDNN libraries.

   • Using pip (a virtual environment is recommended):

     pip install -r requirements.txt
     

     You will need Python 3.6 because we use a version of TensorFlow which is not available from PyPI for more recent Python versions.

   The code has been tested with TensorFlow 1.12, CUDA 9.0 and CuDNN 7.6.0. Other versions of TensorFlow (1.x) may work too.

2. Install the package with:

   pip install './code[gpu]'
   

Usage

The main entry point of the package is the groove2groove.models.roll2seq_style_transfer module, which takes care of training and running the model. Run python -m groove2groove.models.roll2seq_style_transfer -h to see the available command line arguments.

The train command runs the training:

python -m groove2groove.models.roll2seq_style_transfer --logdir $LOGDIR train

Replace $LOGDIR with the model directory, containing the model.yaml configuration file (e.g. one of the directories under experiments).

To run a trained model on a single pair of MIDI files, use the run-midi command, e.g.:

python -m groove2groove.models.roll2seq_style_transfer --logdir $LOGDIR run-midi \
    --sample --softmax-temperature 0.6 \
    content.mid style.mid output.mid

To run it on a whole pre-processed dataset (e.g. the one in data/bodhidharma), use the run-test command, e.g.:

python -m groove2groove.models.roll2seq_style_transfer --logdir $LOGDIR run-test \
    --sample --softmax-temperature 0.6 --batch-size 128 \
    content.db style.db keypairs.tsv output.db 

Here, keypairs.tsv lists on each line a key from content.db and a key from style.db to use as inputs. Note that content.db and style.db may be the same file.
