假如在TensorFlow中工作,tf.sort()是非常直观的记忆和使用方法。只需记住direction = descending可转换排序顺序。 PyTorch torch.sort(my_tensor)返回tensor排序副本。可选参数有: dim:{int,optional} - 待排序维度 descending:{bool,optional} - 控制排序顺序(升序或降序)。 out:{tuple,optional} - (Tensor,LongT...

tf.sort(my_tensor)返回tensor排序副本。可选参数有: axis:{int,optional}待排序轴。默认值为-1,对最后一个轴进行排序。 direction:{ascending or descending}—数值排序的方向。 name:{str,optional}—操作的名称。 tf.sort在幕后使用top_k()方法。top_k使用CUB库的CUDA GPU促使并行性更容易实现。正如文档所...
