分步解析数据处理代码
- 使用的时候是调用load_and_cache_examples(args, tokenizer, mode)函数，其中args参数用于传入初始化的一些参数设置，tokenizer用于将字或符号转换为相应的数字,mode用于标识是训练数据还是验证或者测试数据。
- 在load_and_cache_examples函数中首先调用processorsargs.task，这个processors是一个字典，字典的键是数据集名称，值是处理该数据集的函数名，当我们使用其它的数据集的时候，我们也要在这里面添加相关的键值对表示。
- 随后将args参数传入到SemEvalProcessor()函数中。该函数的作用就是生成每一个样本，每一个样本用InputExample类表示，包括样本的唯一标识，文本，标签，最后返回的是包含多个InputExample的列表。
- 随后通过
convert_examples_to_features(
examples, args.max_seq_len, tokenizer, add_sep_token=args.add_sep_token
)
针对于每一个example，都要求得：
input_ids=input_ids,
attention_mask=attention_mask,
token_type_ids=token_type_ids,
label_id=label_id,
e1_mask=e1_mask,
e2_mask=e2_mask,
然后封装成一个InputFeatures，最后返回一个包含多个InputFeatures的列表。
其中还有一些细节我们要清楚的：- 需要将实体<e1>、</e1>用$表示，实体<e2>、</e2>用#表示
- 由于加入了[cls]，因此其对应的索引位置要+1
- 是否需要加入[sep]时要考虑
- 句子不够长要进行填补，句子太长了要进行截断
- 最后我们得到相关的列表：
dataset = TensorDataset(
all_input_ids,
all_attention_mask,
all_token_type_ids,
all_label_ids,
all_e1_mask,
all_e2_mask,
)
将其转换成TensorDataset并返回。

并生成一个：cached_train_semeval_bert-base-uncased_384文件
补充
最后是相关的使用方法：
train_dataset = load_and_cache_examples(args, tokenizer, mode="train")
train_sampler = RandomSampler(train_dataset)
train_dataloader = DataLoader(
self.train_dataset,
sampler=train_sampler,
batch_size=self.args.train_batch_size,
)
