NeMo is a toolkit for creating Conversational AI applications.
The toolkit comes with extendable collections of pre-built modules and ready-to-use models for Automatic Speech Recognition (ASR), Natual Language Processing (NLP) and Text-to-Speech (TTS).
Built for speed, NeMo can utilize NVIDIA's Tensor Cores and scale out training to multiple GPUs and multiple nodes.
- Python 3.6, 3.7 or 3.8
- Pytorch 1.7.1. WARNING: This version currently does not support Pytorch 1.8.0
- NVIDIA GPU for training
Version | Status | Description |
---|---|---|
Latest | Documentation of the latest (i.e. main) branch. | |
Next | Documentation of the next release (i.e. r1.0.0rc1). | |
Stable | Documentation of the stable (i.e. stable) branch. |
A great way to start with NeMo is by checking one of our tutorials.

Use this installation mode if you want the latest released version.
apt-get update && apt-get install -y libsndfile1 ffmpeg
pip install Cython
pip install nemo_toolkit[all]==1.0.0b3
Use this installation mode if you want the a version from particular GitHub branch (e.g main).
apt-get update && apt-get install -y libsndfile1 ffmpeg
pip install Cython
python -m pip install git+https://github.com/NVIDIA/NeMo.git@{BRANCH}#egg=nemo_toolkit[all]
Use this installation mode if you are contributing to NeMo.
apt-get update && apt-get install -y libsndfile1 ffmpeg
git clone https://github.com/NVIDIA/NeMo
cd NeMo
./reinstall.sh
The easiest way to start training with NeMo is by using NeMo's container. It has all requirements and NeMo 1.0.0b3 already installed.
docker run --gpus all -it --rm --shm-size=8g \
-p 8888:8888 -p 6006:6006 --ulimit memlock=-1 --ulimit \
stack=67108864 --device=/dev/snd nvcr.io/nvidia/nemo:1.0.0b3
If you chose to work with main branch, we recommend using NVIDIA's PyTorch container version 20.11-py3 and then installing from GitHub.
docker run --gpus all -it --rm -v <nemo_github_folder>:/NeMo --shm-size=8g \
-p 8888:8888 -p 6006:6006 --ulimit memlock=-1 --ulimit \
stack=67108864 --device=/dev/snd nvcr.io/nvidia/pytorch:20.11-py3
