这一部分介绍如何用一个 GPU 在 ``WN18RR`` 知识图谱上训练 ``RotatE`` :cite:`RotatE`，使用 ``wandb`` 记录实验结果。

导入数据
-----------------
UniKE 有 1 个工具用于导入数据: :py:class:`unike.data.KGEDataLoader`。

from unike.data import KGEDataLoader, UniSampler, TradTestSampler

# 导入模型
# ------------------
# UniKE 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
# :py:class:`unike.module.model.RotatE`，它将实体表示成复数向量，关系建模为复数向量空间的旋转。

# define the model
rotate = RotatE(
	ent_tol = dataloader.get_ent_tol(),
	rel_tol = dataloader.get_rel_tol(),
	dim = config.dim,
	margin = config.margin,
	epsilon = config.epsilon,
)

# 损失函数
# ----------------------------------------
# 我们这里使用了逻辑损失函数：:py:class:`unike.module.loss.SigmoidLoss`，
# :py:class:`unike.module.strategy.NegativeSampling` 对
# :py:class:`unike.module.loss.SigmoidLoss` 进行了封装，加入权重衰减等额外项。

# define the loss function
model = NegativeSampling(
	model = rotate, 
	loss = SigmoidLoss(adv_temperature = config.adv_temperature),
	regul_rate = config.regul_rate
)

# 训练模型
# -------------
# UniKE 将训练循环包装成了 :py:class:`unike.config.Trainer`，
# 可以运行它的 :py:meth:`unike.config.Trainer.run` 函数进行模型学习；
# 也可以通过传入 :py:class:`unike.config.Tester`，
# 使得训练器能够在训练过程中评估模型；:py:class:`unike.config.Tester` 使用
# :py:class:`unike.data.TestDataLoader` 作为数据采样器。

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

# train the model
trainer = Trainer(model = model, data_loader = dataloader.train_dataloader(), epochs = config.epochs,
	lr = config.lr, opt_method = config.opt_method, use_gpu = config.use_gpu, device = config.device,
	tester = tester, test = config.test, valid_interval = config.valid_interval,
	log_interval = config.log_interval, save_interval = config.save_interval,
	save_path = config.save_path, wandb_logger = wandb_logger)
trainer.run()

# close your wandb run
wandb_logger.finish()
