To train the Conformer CTC and Quartznet, you need nemo. It's recommended to use a fresh Conda env.
conda create --name nemo python==3.8
conda activate nemo
conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
apt-get update && apt-get install -y libsndfile1 ffmpeg
pip install Cython
pip install nemo_toolkit['all']
You first need to build the manifests of each toolkit by running the python files in the corresponding directories (see the Manifests folder).
