Repository Details

Repo for external large-scale work

Metaseq

A codebase for working with Open Pre-trained Transformers, originally forked from fairseq.

Community Integrations

Using OPT with ๐Ÿค— Transformers

The OPT 125M--66B models are now available in Hugging Face Transformers. You can access them under the facebook organization on the Hugging Face Hub

Using OPT-175B with Alpa

The OPT 125M--175B models are now supported in the Alpa project, which enables serving OPT-175B with more flexible parallelisms on older generations of GPUs, such as 40GB A100, V100, T4, M60, etc.

Using OPT with Colossal-AI

The OPT models are now supported in the Colossal-AI, which helps users to efficiently and quickly deploy OPT models training and inference, reducing large AI model budgets and scaling down the labor cost of learning and deployment.

Using OPT with CTranslate2

The OPT 125M--66B models can be executed with CTranslate2, which is a fast inference engine for Transformer models. The project integrates the SmoothQuant technique to allow 8-bit quantization of OPT models. See the usage example to get started.

Using OPT with FasterTransformer

The OPT models can be served with FasterTransformer, a highly optimized inference framework written and maintained by NVIDIA. We provide instructions to convert OPT checkpoints into FasterTransformer format and a usage example with some benchmark results.

Using OPT with DeepSpeed

The OPT models can be finetuned using DeepSpeed. See the DeepSpeed-Chat example to get started.

Getting Started in Metaseq

Follow setup instructions here to get started.

denoiser

Real Time Speech Enhancement in the Waveform Domain (Interspeech 2020)We provide a PyTorch implementation of the paper Real Time Speech Enhancement in the Waveform Domain. In which, we present a causal speech enhancement model working on the raw waveform that runs in real-time on a laptop CPU. The proposed model is based on an encoder-decoder architecture with skip-connections. It is optimized on both time and frequency domains, using multiple loss functions. Empirical evidence shows that it is capable of removing various kinds of background noise including stationary and non-stationary noises, as well as room reverb. Additionally, we suggest a set of data augmentation techniques applied directly on the raw waveform which further improve model performance and its generalization abilities.
