Prerequisites:

1. python 2.7
2. cuda 9.0
3. cuDNN v7.6.2
4. sudo apt-get install ffmpeg
5. pip install -r requirments.txt

Data

1. Download the dataset as described here

Instructions

1. Extract training/validation data
2. Train a model
3. Perform inference using a trained model

Extract training data

Start by extracting training data:

python -m data.train_test_data_extraction.extract_data_for_training --base_dataset_path <base_path> --speaker <speaker_name> -np <number of processes> --speaker <speaker name>`

once done you should see the following directories structure:
(notice train.csv and a train folder within the relevant speaker)

Gestures
├── frames.csv
├── train.csv
├── almaram
    ├── frames
    ├── videos
    ├── keypoints_all
    ├── keypoints_simple
    ├── videos
    └── train

└── shelly

    ├── keypoints_simple
    ├── videos
    └── train

train.csv is a csv file in which every row represents a single training sample. Unlike in frames.csv, here, a sample is few seconds long.

Columns documentation:

audio_fn - path to audio filename associated with training sample
dataset - train/dev/test
start - start time in the video
end - end time in the video
pose_fn - path to .npz file containing training sample
speaker - name of a speaker in the dataset
video_fn - name of the video file

Training a speaker specific model

Training run command example:

python -m audio_to_multiple_pose_gan.train --gans 1 --name test_run --arch_g audio_to_pose_gans --arch_d pose_D --speaker oliver --output_path /tmp

During training, example outputs are saved in the define output_path

Inference

optionally get a pretrained model here.

Perform inference on a random sample from validation set:

python -m audio_to_multiple_pose_gan.predict_to_videos --train_csv <path/to/train.csv>--seq_len 64 --output_path </tmp/my_output_folder> --checkpoint <model checkpoint path> --speaker <speaker_name> -ag audio_to_pose_gans --gans 1

Perform inference on an audio sample:

python -m audio_to_multiple_pose_gan.predict_audio --audio_path <path_to_file.wav> --output_path </tmp/my_output_folder> --checkpoint <model checkpoint path> --speaker <speaker_name> -ag audio_to_pose_gans --gans 1
