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 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.

- 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
- [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]"
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.
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.
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.

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.
