I have a TSV file training_abstracts.tsv when I use the function: ‘def test1(): with open('F:\small paper\ner\data_file\training_abstracts.tsv', 'r', encoding='utf-8') as f1: line = f1.readline() while line: list1 = line.split('\t') text = list1[1] bio = list1[2] if len(tokenizer(text)) != len(bio.split()): print('len(tokenizer(text)):', len(tokenizer(text))) print('len(bio.split()):', len(bio.split())) print(line) line = f1.readline()’

When testing it, the length of the text column is the same as the length of the tag column, but when I define: ‘text = data.Field(batch_first=True, include_lengths=True, tokenize=tokenizer, lower=True) tag = data.Field(batch_first=True, include_lengths=True)’, during the experiment, there is a situation where the length of the text column and the length of the tag column are inconsistent. Why?

Other related code: ‘train_data, val_data, test_data = data.TabularDataset.splits(path='data_file/', train='training_abstracts.tsv', validation='development_abstracts.tsv', test='evaluation_abstracts.tsv', fields=[('pmid', None), ('text', text), ('tag', tag)], format='tsv')’

‘train_loader, val_loader, test_loader = data.BucketIterator.splits((train_data, val_data, test_data), batch_sizes=batch_sizes, sort_key=lambda x: len(x.text), sort_within_batch=True, repeat=False)’
