To convert a given list of characters into a string, there are two approaches, Using the loop– traverse of the list i.e. extracts characters from the list and add characters to the string. Using join() function– a list of characters can be converted into a string by joining the charac...

string.count('x'): 这将返回字符串中'x'的出现次数 string.find('x'): 这将返回字符串中字符'x'的位置 string.lower(): 这将把字符串转换为小写 string.upper(): 这将把字符串转换为大写 string.replace('a', 'b'): 这将用b替换字符串中的所有a 此外,我们可以使用len()方法获取字符串中字符的数...

我们可以直接从常见的标记器(如GPT-2和ALBERT (A Lite BERT)标记器)调用预标记化方法。这些方法与上面所示的标准BERT预标记器略有不同,因为在分割标记时不会删除空格字符。它们被替换为表示空格所在位置的特殊字符。这样做的好处是,在进一步处理时可以忽略空格字符,但如果需要,可以检索原始句子。GPT-2模型使用Ġ字...
