FlagAI: A Python repository from YagamiHikari

简体中文

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 representation model AltCLIP and text-to-image generation AltDiffusion . And it supports WuDao GLM with a maximum of 10 billion parameters (see Introduction to GLM). It also supports EVA-CLIP, OPT, BERT, RoBERTa, GPT2, T5, ALM, 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 four most popular data/model parallel libraries — PyTorch/Deepspeed/Megatron-LM/BMTrain — 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，timm and DeepSpeedExamples.

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., 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 environments, generate ssh keys and copy the public key to all nodes (in ~/.ssh/)

>>> ssh-keygen -t rsa -C "xxx@xxx.com"

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 fine-tune 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))

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.

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。***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。",

    "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}")

Semantic Matching

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))

Pre-trained Models and examples

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.
