In order to avoid thisTraceback Error, we can use the keywordinto check if a substring is contained in a string. In the case of Loops, it was used for iteration, whereas in this case it’s a conditional that can be eithertrueorfalse.It’ll be true if the substring is part of the ...

Python3.2前,GIL的释放逻辑是当前线程遇见IO操作或者ticks计数达到100(ticks可以看作是python自身的一个计数器,专门做用于GIL,每次释放后归零,这个计数可以通过 sys.setcheckinterval 来调整),进行释放。因为计算密集型线程在释放GIL之后又会立即去申请GIL,并且通常在其它线程还没有调度完之前它就已经重新获取到了GIL,就...
1 if __name__=='__main__': 2 test() __name__ 是当前模块名,当模块被直接运行时模块名为 __main__ 。这句话的意思就是,当模块被直接运行时,代码将被运行,当模块是被导入时,代码不被运行。 更好的例子是为了代码重用。比如你现在写了一些程序,都存在单独的py文件里。有一天你突然想用1.py文件...

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...
