Dataset split python
WebThe split argument can actually be used to control extensively the generated dataset split. You can use this argument to build a split from only a portion of a split in absolute number of examples or in proportion (e.g. split='train[:10%]' will load only the first 10% of the train split) or to mix splits (e.g. split='train[:100]+validation[:100]' will create a split from the … Web这将输出['31.20'、'121.36']。 谢谢!我以前使用过split函数,但不知道它的参数。很高兴知道。它比我原来想的有用。
