Releases: NVIDIA/NeMo
NVIDIA Neural Modules 1.0.0
Release 1.0.0
NeMo 1.0.0 release is a stable version of "1.0.0 release candidate". It substantially improves overall quality and documentation. This update adds support for new tasks such as neural machine translation and many new models pretrained in different languages. As a mature tool for ASR and TTS it also adds new features for text normalization and denormalization, dataset creation based on CTC-segmentation and speech data explorer. These updates will benefit researchers in academia and industry by making it easier for them to develop and train new conversational AI models.
To install this specific version from pip do:
apt-get update && apt-get install -y libsndfile1 ffmpeg
pip install Cython
pip install nemo-toolkit['all']==1.0.0
NVIDIA Neural Modules 1.0.0rc1
Release 1.0.0rc1
This release contains major new models, features and docs improvements.
It is a "candidate" release for 1.0.0.
To install from Pip do:
apt-get update && apt-get install -y libsndfile1 ffmpeg
pip install Cython
pip install nemo_toolkit['all']==1.0.0rc1
It adds the following model architectures:
- CitriNet and Conformer-CTC for ASR
- HiFiGan, MelGan, GlowTTS, UniGlow SqueezeWave for TTS
In NLP collections, a neural machine translation task (NMT) has been added with Transformer-based models.
This release includes pre-trained NMT models for these language pairs (in both directions):
- En<->Es
- En<->Ru
- En<->Zh
- En<->De
- En<->Fr
For ASR task, we also added QuartzNet models, trained on the following languages from Mozilla's Common Voice dataset: Zh, Ru, Es, Pl, Ca, It, Fr and De.
In total, this release adds 60 new pre-trained models.
This release also adds new NeMo tools for:
- Text normalization
- Dataset Creation Tool Based on CTC-Segmentation
- Speech Data Explorer

Toolkit in an early version software.
NVIDIA Neural Modules 1.0.0b1
Release 1.0.0b1
This release is a major re-design compared to previous version.
All NeMo models and modules are now compatible out-of-the box with Pytorch and Pytorch Lightning.
Every NeMo model is a LightningModule that comes equipped with all supporting infrastructure for training and reproducibility. Every NeMo model has an example configuration file and a corresponding script that contains all configurations needed for training. NeMo, Pytorch Lightning, and Hydra makes all NeMo models have the same look and feel so that it is easy to do Conversational AI research across multiple domains. New models such as Speaker verification and Megatron are added.
Highlights
- Pytorch Lightning based Core
- Hydra and Omegaconf configuration management
- All model's files tarred together as .nemo files make it easy for users to download models automatically from NGC
- NGC collections now includes a collection of all NeMo assets in one
- New Models & tutorials
- ASR: SpeakerNet speaker verification model
- NLP: Bio Megatron state of the art model trained on bio medical tasks
- ASR, NLP and TTS tutorials as interactive notebooks
Known Issues
Toolkit in an early version software. Breaking changes compared to previous version.
Resolved Issues
All models and modules can be used anywhere torch.nn.Module
is expected.
