Prerequisites:
python 2.7cuda 9.0cuDNN v7.6.2sudo apt-get install ffmpegpip install -r requirments.txt
Data
- Download the dataset as described here
Instructions
- Extract training/validation data
- Train a model
- 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

  └── 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
