如何将 pandas 多列文本转换为张量？

Question

您好，我正在研究关键点分析任务，由IBM共享，这里是link. In the given dataset there are more than one rows of text and anyone can please tell me how can I convert the text columns into tensors and again assign them in the same dataFrame because there are other columns of data there.

问题

这里我面临一个问题，我以前从未见过这种数据，比如有多个文本列，如何将所有这些列转换为张量，然后应用模型。大多数时候数据就像：一个文本列其他列是标签，示例：电影评论，有毒评论分类。

def clean_text(text):
"""
    text: a string

    return: modified initial string
"""
text = text.lower()  # lowercase text
text = REPLACE_BY_SPACE_RE.sub(' ',
                               text)  
text = BAD_SYMBOLS_RE.sub('',
                          text)  
text = text.replace('x', '')
#    text = re.sub(r'\W+', '', text)
text = ' '.join(word for word in text.split() if word not in STOPWORDS) 
return text

Answer 1

如果我答对了你的问题，你会做如下事情：

from transformers import RobertaTokenizer
tokenizer = RobertaTokenizer.from_pretrained("roberta-base")
DF["args"]=DF["args"].apply(lambda x:tokenizer(x)['input_ids'])

这会将句子转换为标记数组。
