这一部分介绍如何用一个 GPU 在 FB15K237 知识图谱上训练 TransR [LLS+15],使用 wandb 记录实验结果。

导入数据

pybind11-OpenKE 有两个工具用于导入数据: pybind11_ke.data.KGEDataLoader

from pybind11_ke.utils import WandbLogger
from pybind11_ke.data import KGEDataLoader, BernSampler, TradTestSampler
from pybind11_ke.module.model import TransE, TransR
from pybind11_ke.module.loss import MarginLoss
from pybind11_ke.module.strategy import NegativeSampling
from pybind11_ke.config import Trainer, Tester

首先初始化 pybind11_ke.utils.WandbLogger 日志记录器,它是对 wandb 初始化操作的一层简单封装。

wandb_logger = WandbLogger(
    project="pybind11-ke",
    name="TransR-FB15K237",
    config=dict(
            in_path = '../../benchmarks/FB15K237/',
            batch_size = 2048,
            neg_ent = 25,
            test = True,
            test_batch_size = 10,
            num_workers = 16,
            dim = 100,
            dim_e = 100,
            dim_r = 100,
            p_norm = 1,
            norm_flag = True,
            rand_init = False,
            margin_e = 5.0,
            margin_r = 4.0,
            epochs_e = 1,
            lr_e = 0.5,
            opt_method = "sgd",
            use_gpu = True,
            device = 'cuda:0',
            epochs_r = 1000,
            lr_r = 1.0,
            valid_interval = 100,
            log_interval = 100,
            save_interval = 100,
            save_path = '../../checkpoint/transr.pth'
    )
)

config = wandb_logger.config

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 = config.in_path,
    batch_size = config.batch_size,
    neg_ent = config.neg_ent,
    test = config.test,
    test_batch_size = config.test_batch_size,
    num_workers = config.num_workers,
    train_sampler = BernSampler,
    test_sampler = TradTestSampler
)

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。我们首先导入 pybind11_ke.module.model.TransE,它是最简单的平移模型, 因为为了避免过拟合,pybind11_ke.module.model.TransR 实体和关系的嵌入向量初始化为 pybind11_ke.module.model.TransE 的结果。

# define the transe
transe = TransE(
    ent_tol = dataloader.get_ent_tol(),
    rel_tol = dataloader.get_rel_tol(),
    dim = config.dim,
    p_norm = config.p_norm,
    norm_flag = config.norm_flag)

下面导入 pybind11_ke.module.model.TransR 模型, 是一个为实体和关系嵌入向量分别构建了独立的向量空间,将实体向量投影到特定的关系向量空间进行平移操作的模型。

transr = TransR(
    ent_tol = dataloader.get_ent_tol(),
    rel_tol = dataloader.get_rel_tol(),
    dim_e = config.dim_e,
    dim_r = config.dim_r,
    p_norm = config.p_norm,
    norm_flag = config.norm_flag,
    rand_init = config.rand_init)

损失函数

我们这里使用了 TransE [BUGD+13] 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。

model_e = NegativeSampling(
    model = transe,
    loss = MarginLoss(margin = config.margin_e)
)

model_r = NegativeSampling(
    model = transr,
    loss = MarginLoss(margin = config.margin_r)
)

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; 也可以通过传入 pybind11_ke.config.Tester, 使得训练器能够在训练过程中评估模型。

# pretrain transe
trainer = Trainer(model = model_e, data_loader = dataloader.train_dataloader(),
    epochs = config.epochs_e, lr = config.lr_e, opt_method = config.opt_method,
    use_gpu = config.use_gpu, device = config.device)
trainer.run()
parameters = transe.get_parameters()
transe.save_parameters("../../checkpoint/transr_transe.json")

# test the transr
tester = Tester(model = transr, data_loader = dataloader, use_tqdm = False,
                use_gpu = config.use_gpu, device = config.device)

# train transr
transr.set_parameters(parameters)
trainer = Trainer(model = model_r, data_loader = dataloader.train_dataloader(),
    epochs = config.epochs_r, lr = config.lr_r, opt_method = config.opt_method,
    use_gpu = config.use_gpu, device = config.device,
    tester = tester, test = True, valid_interval = config.valid_interval,
    log_interval = config.log_interval, save_interval = config.save_interval,
    save_path = config.save_path, use_wandb = True)
trainer.run()
