FlagAI (Fast LArge-scale General AI models) is a fast, easy-to-use and extensible toolkit for large-scale model. Our goal is to support training, fine-tuning, and deployment of large-scale models on various downstream tasks with multi-modality.

• Now it supports text-image multi-modal model AltCLIP and text-to-imge model AltDiffusion. And it support WuDao GLM with a maximum of 10 billion parameters (see Introduction to GLM). It also supports OPT, BERT, RoBERTa, GPT2, T5, and models from Huggingface Transformers.

• It provides APIs to quickly download and use those pre-trained models on a given text, fine-tune them on widely-used datasets collected from SuperGLUE and CLUE benchmarks, and then share them with the community on our model hub. It also provides prompt-learning toolkit for few shot tasks.

• These models can be applied to (Chinese/English) Text, for tasks like text classification, information extraction, question answering, summarization, and text generation.

• FlagAI is backed by the three most popular data/model parallel libraries — PyTorch/Deepspeed/Megatron-LM — with seamless integration between them. Users can parallel their training/testing process with less than ten lines of code.

The code is partially based on GLM, Transformers and DeepSpeedExamples.

Requirements and Installation

• PyTorch version >= 1.8.0
• Python version >= 3.8
• For training/testing models on GPUs, you'll also need install CUDA and NCCL

To install FlagAI with pip:

pip install -U flagai

• [Optional]To install FlagAI and develop locally:

git clone https://github.com/FlagAI-Open/FlagAI.git
python setup.py install

• [Optional] For faster training install NVIDIA's apex

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

• [Optional] For ZeRO optimizers install DEEPSPEED

git clone https://github.com/microsoft/DeepSpeed
cd DeepSpeed
DS_BUILD_CPU_ADAM=1 DS_BUILD_AIO=1 DS_BUILD_UTILS=1 pip install -e .
ds_report # check the deespeed status

• [Tips] For single-node docker enviroments, we need to setup ports for your ssh. e.g., root@127.0.0.1 with port 7110

>>> vim ~/.ssh/config
Host 127.0.0.1
    Hostname 127.0.0.1
    Port 7110
    User root

• [Tips] For multi-node docker enviroments, generate ssh keys and copy the public key to all nodes (in ~/.ssh/)

>>> ssh-keygen -t rsa -C "[e-mail]"

Quick Start

We provide many models which are trained to perform different tasks. You can load these models by AutoLoader to make prediction. See more in FlagAI/quickstart.

Load model and tokenizer

We provide the AutoLoad class to load the model and tokenizer quickly, for example:

from flagai.auto_model.auto_loader import AutoLoader

auto_loader = AutoLoader(
    task_name="title-generation",
    model_name="BERT-base-en"
)
model = auto_loader.get_model()
tokenizer = auto_loader.get_tokenizer()

This example is for the title_generation task, and you can also model other tasks by modifying the task_name. Then you can use the model and tokenizer to finetune or test.

Predictor

We provide the Predictor class to predict for different tasks, for example:

from flagai.model.predictor.predictor import Predictor
predictor = Predictor(model, tokenizer)
test_data = [
    "Four minutes after the red card, Emerson Royal nodded a corner into the path of the unmarked Kane at the far post, who nudged the ball in for his 12th goal in 17 North London derby appearances. Arteta's misery was compounded two minutes after half-time when Kane held the ball up in front of goal and teed up Son to smash a shot beyond a crowd of defenders to make it 3-0.The goal moved the South Korea talisman a goal behind Premier League top scorer Mohamed Salah on 21 for the season, and he looked perturbed when he was hauled off with 18 minutes remaining, receiving words of consolation from Pierre-Emile Hojbjerg.Once his frustrations have eased, Son and Spurs will look ahead to two final games in which they only need a point more than Arsenal to finish fourth.",
]

for text in test_data:
    print(
        predictor.predict_generate_beamsearch(text,
                                              out_max_length=50,
                                              beam_size=3))

Pretrained Models and examples

• Blank_Filling_QA with GLM
• Title Generation with GLM
• Poetry generation with GLM-large-ch
• Using huggingface's t5-11b & tricks
• Title Generation with RoBerta-WWM

• Example of OPT

This session explains how the base NLP classes work, how you can load pre-trained models to tag your text, how you can embed your text with different word or document embeddings, and how you can train your own language models, sequence labeling models, and text classification models. Let us know if anything is unclear. See more in FlagAI/examples.
