这一部分介绍如何用一个 GPU 在 FB15K237 知识图谱上训练 RESCAL [NTK11]

导入数据

pybind11-OpenKE 有 1 个工具用于导入数据: pybind11_ke.data.KGEDataLoader

from pybind11_ke.data import KGEDataLoader
from pybind11_ke.module.model import RESCAL
from pybind11_ke.module.loss import MarginLoss
from pybind11_ke.module.strategy import NegativeSampling
from pybind11_ke.config import Trainer, Tester

pybind11-OpenKE 提供了很多数据集,它们很多都是 KGE 原论文发表时附带的数据集。 pybind11_ke.data.KGEDataLoader 包含 in_path 用于传递数据集目录。

# dataloader for training
dataloader = KGEDataLoader(
    in_path = "../../benchmarks/FB15K237/",
    batch_size = 2048,
    neg_ent = 25,
    test = True,
    test_batch_size = 10,
    num_workers = 16
)

导入模型

pybind11-OpenKE 提供了很多 KGE 模型,它们都是目前最常用的基线模型。我们下面将要导入 pybind11_ke.module.model.RESCAL,它是很多张量分解模型改进的基础。

# define the model
rescal = RESCAL(
    ent_tol = dataloader.get_ent_tol(),
    rel_tol = dataloader.get_rel_tol(),
    dim = 50
)

损失函数

我们这里使用了 TransE 原论文使用的损失函数:pybind11_ke.module.loss.MarginLosspybind11_ke.module.strategy.NegativeSamplingpybind11_ke.module.loss.MarginLoss 进行了封装,加入权重衰减等额外项。

# define the loss function
model = NegativeSampling(
    model = rescal,
    loss = MarginLoss(margin = 1.0)
)

训练模型

pybind11-OpenKE 将训练循环包装成了 pybind11_ke.config.Trainer, 可以运行它的 pybind11_ke.config.Trainer.run() 函数进行模型学习。

# test the model
tester = Tester(model = rescal, data_loader = dataloader, use_tqdm = False,
                use_gpu = True, device = 'cuda:1')

# train the model
trainer = Trainer(model = model, data_loader = dataloader.train_dataloader(), epochs = 1000,
    lr = 0.1, opt_method = 'adagrad', use_gpu = True, device = 'cuda:1',
    tester = tester, test = True, valid_interval = 100,
    log_interval = 100, save_interval = 100,
    save_path = '../../checkpoint/rescal.pth', use_wandb = False)
trainer.run()
