dtc Dueling Turing Classifier

The idea for this project was motivated primarily by Turing’s influential paper "Computing Machinery and Intelligence" [1]

First of all, I think most researchers who use datasets must and should acknowledge this LJ for this fantastic dataset.

This repository is the PyTorch implementation.

This repository is the PyTorch implementation and improvements and some new ideas focused on Tacotron 2 and WaveGlow

Installation

The code has been tested over PyTorch latest version 1.10 and Python 3.9 and 3.10

Install PyTorch following the instructions on the official website.
Check requirement files.

conda env create -f environment.yml
conda activate dtc
conda install pytorch torchvision torchaudio  -c pytorch

Note Trainer and code base ready for hyperparameter tunning , hence you want install Ray.

pip install ray  # minimal install

We can run code in colab, jupiter or standalone app.

 For Colab you need follow colab notebook.

Then install the other dependencies.

pip install -r requirements.txt

First create config.yaml file

Download Datasets

Note Datasets abstraction provide option to download a dataset, either as raw , torch tensor or numpy.

Convert and generate datasets

You want to do that only if you want to serialize the torch tensor on disk.

main.py --convert --dataset_name LJSpeech

Workspace

By default trainer will create results folder, for example if you will run python main.py it will create results folder and all sub folders

root_dir: "."
log_dir: "logs"
nil_dir: "timing"
graph_dir: "graphs"
results_dir: "results"
figures_dir: "figures"
prediction_dir: "prediction"               # where we save prediction
model_save_dir: "model"                    # where we save model
metrics_dir: "metrics"                     # metrics dir in case we need store separate metrics
generated_dir: "generated"                 # inference time generated here.

Datasets defined in datasets section. The global parameter use_dataset dictates what dataset active at given moment.

The idea here we can have different type dataset, each dataset has different type. For raw audio dataset.

The idea here is that we can have a different type of dataset. Each dataset has a different style and structure. For the raw audio dataset.

ds_type: "audio"
file_type: "wav"

FOr example if you are using LJSpeech-1.1

datasets:
  LJSpeech:
    format: raw
    ds_type: "audio"
    file_type: "wav"
    dir: "~/Dropbox/Datasets/LJSpeech-1.1"
    training_meta: ljs_audio_text_train_filelist.txt
    validation_meta: ljs_audio_text_val_filelist.txt
    test_meta: ljs_audio_text_test_filelist.txt
    meta: metadata.csv
    recursive: False
  lj_speech_full:
    format: tensor_mel
    ds_type: "audio"
    dir: "~/Dropbox/Datasets/LJSpeech-1.1"
    dataset_files:
      - "LJSpeech_train_num_sam_12500_filter_80_3.pt"
      - "LJSpeech_validate_num_sam_100_filter_80_3.pt"
      - "LJSpeech_test_num_sam_500_filter_80_3.pt"
    training_meta: LJSpeech_train_num_sam_12500_filter_80_3.pt
    validation_meta: LJSpeech_validate_num_sam_100_filter_80_3.pt
    test_meta: LJSpeech_test_num_sam_500_filter_80_3.pt
    checksums:
      - "7bc0f1bac289cfd1ba8ea1c390bddf8f"
      - "5d3b94b131c08afcca993dfbec54c63a"
      - "3291d802351928da7c5d0d9c917c2663"
    meta: metadata.csv
    recursive: False
    file_type: "torch"

Second section. lj_speech_full already converted dataset to torch.tensor format. So all Spectrogram, SFTS and text serialized a tensor.

Model and Optimizer settings.

All model specs defined in models , you can also define different optimizer settings and bind specific optimizer for a model.

Note that model are just symbolic names, internally trainer uses model: to dispatch to correct factory method.

Large scale training.

If you have large GPU 48Gb you should be able to fit 128 batch size. My recommendation save per single epoch. In case you want save incrementally adjust save_per_iteration flag and set value 500. So every 500 steps trainer will a model.

Trainer logic

All trainer logic is abstracted in the generic trainer. During the initial start, the trainer takes specs, i.e., the yaml file invokes the factory method. That creates a model, a model-specific optimizer, and a scheduler. Note my assumption that the model can be stacked. Hence, internally, it queues. So, for example, if you have two models and train both, you can define two sub-layers. A good example is if you want to train DTC with a different Vocoder or,
for instance, Tacotron 2 and WaveGlow. Note that trainers execute epochs in a sequence. Hence, queue is just FIFO.
