sort(a).numpy() array([ 1. , 2.8 , 10. , 26.9 , 62.3 , 166.32], dtype=float32) tf.sort(a, direction='DESCENDING').numpy() array([166.32, 62.3 , 26.9 , 10. , 2.8 , 1. ], dtype=float32) 对于多维输入,您可以控制沿哪个轴应用排序。默认的axis=-1 对最里面的轴进行排序。 mat ...
Yes, it does. I found this discussion and used flip in my code. It works. here"descending" is used It looks like the array API chosedescendingto match TensorFlow; seehere. (I don't mean to try to justify that choice; I just see that was the rationale given.) Based on#25076 (comm...
>>> s = sorted(student_objects, key=attrgetter('age'))#sort on secondary key>>> sorted(s, key=attrgetter('grade'), reverse=True)#now sort on primary key, descending[('dave','B', 10), ('jane','B', 12), ('john','A', 15)] 6)numpy中数组矩阵的排序方法argsort() argsort(a, ...
That’s basically what NumPy sort does … it sorts NumPy arrays. Let me give you a quick example. Imagine that you have a 1-dimensional NumPy array with five values that are in random order: You can use NumPy sort tosortthose values in ascending order. Essentially, numpy.sort will take...

Sorting a NumPy array in descending order sorts the elements from largest to smallest value. You can use the syntaxarray[::-1]to reverse the array. # Sort array in descending order array = np.sort(array)[::-1] print("Sorted descending order:\n",array) ...
