vector2d.py: a simplistic class demonstrating some special methods It is simplistic for didactic reasons. It lacks proper error handling, especially in the ``__add__`` and ``__mul__`` methods. This example is greatly expanded later in the book. Addition:: >>> v1 = Vector(2, 4) >...

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...
