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.

Why should I use FlagAI?

1. Quickly Download Models via API

   FlagAI provides an API that allows you to quickly download pre-trained models and fine-tune them on a wide range of datasets collected from SuperGLUE and CLUE benchmarks for both Chinese and English text.

   FlagAI now supports over 30 mainstream models, including multilingual text and image representation model AltCLIP, text-to-image generation model AltDiffusion , WuDao GLM (with a maximum of 10 billion parameters), EVA-CLIP, OPT, BERT, RoBERTa, GPT2, T5, ALM, and models from Huggingface Transformers, etc.

2. Parallel train with fewer than 10 lines of code

   Backed by the four most popular data/model parallel libraries -- PyTorch, Deepspeed, Megatron-LM, BMTrain -- FlagAI allows for seamless integration between them, enabling users to parallel their training/testing process with fewer than ten lines of code.

3. Conveniently use the few-shot learning toolkits

   FlagAI also provides prompt-learning toolkit for few-shot tasks.

4. Particularly good at Chinese tasks

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

Toolkits and Pre-trained Models

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

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.

Requirements and Installation

• Python version >= 3.8
• PyTorch version >= 1.8.0
• [Optional] For training/testing models on GPUs, you'll also need to 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

• [Optional] For BMTrain training, install BMTrain

git clone https://github.com/OpenBMB/BMTrain
cd BMTrain
python setup.py install

• [Tips] For single-node docker environments, we need to set up ports for your ssh. e.g., [email protected] 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 environments, generate ssh keys and copy the public key to all nodes (in ~/.ssh/)

>>> ssh-keygen -t rsa -C "[email protected]"

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 fine-tune or test.

Examples

1. 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))

This example is for the seq2seq task, where we can get beam-search results by calling the predict_generate_beamsearch function. In addition, we also support prediction for tasks such as NER and title generate.

2. NER

from flagai.auto_model.auto_loader import AutoLoader
from flagai.model.predictor.predictor import Predictor

task_name = "ner"
model_name = "RoBERTa-base-ch"
target = ["O", "B-LOC", "I-LOC", "B-ORG", "I-ORG", "B-PER", "I-PER"]
maxlen = 256

auto_loader = AutoLoader(task_name,
                         model_name=model_name,
                         load_pretrain_params=True,
                         class_num=len(target))

model = auto_loader.get_model()
tokenizer = auto_loader.get_tokenizer()

predictor = Predictor(model, tokenizer)

test_data = [
    "6月15日，河南省文物考古研究所曹操高陵文物队公开发表声明承认：“从来没有说过出土的珠子是墓主人的",
    "4月8日，北京冬奥会、冬残奥会总结表彰大会在人民大会堂隆重举行。习近平总书记出席大会并发表重要讲话。在讲话中，总书记充分肯定了北京冬奥会、冬残奥会取得的优异成绩，全面回顾了7年筹办备赛的不凡历程，深入总结了筹备举办北京冬奥会、冬残奥会的宝贵经验，深刻阐释了北京冬奥精神，对运用好冬奥遗产推动高质量发展提出明确要求。",
    "当地时间8日，欧盟委员会表示，欧盟各成员国政府现已冻结共计约300亿欧元与俄罗斯寡头及其他被制裁的俄方人员有关的资产。",
    "这一盘口状态下英国必发公司亚洲盘交易数据显示博洛尼亚热。而从欧赔投注看，也是主队热。巴勒莫两连败，",
]

for t in test_data:
    entities = predictor.predict_ner(t, target, maxlen=maxlen)
    result = {}
    for e in entities:
        if e[2] not in result:
            result[e[2]] = [t[e[0]:e[1] + 1]]
        else:
            result[e[2]].append(t[e[0]:e[1] + 1])
    print(f"result is {result}")

3. Semantic Matching example

from flagai.auto_model.auto_loader import AutoLoader
from flagai.model.predictor.predictor import Predictor

maxlen = 256

auto_loader = AutoLoader("semantic-matching",
                         model_name="RoBERTa-base-ch",
                         load_pretrain_params=True,
                         class_num=2)
model = auto_loader.get_model()
tokenizer = auto_loader.get_tokenizer()

predictor = Predictor(model, tokenizer)

test_data = [["后悔了吗", "你有没有后悔"], ["打开自动横屏", "开启移动数据"],
             ["我觉得你很聪明", "你聪明我是这么觉得"]]

for text_pair in test_data:
    print(predictor.predict_cls_classifier(text_pair))
