Syntax np.asarray(a, dtype=None, order=None) 将结构数据转化为ndarray。 Code # 将list转换为ndarray a = [1, 2] print(np.asarray(a)) # array
To use np.argsort in descending order in Python, first apply np.argsort to our array, and then either invert the result using array slicing ([::-1]) or negate the array before sorting. For inverting, sort the array using np.argsort and then reverse the resulting indices. For negating, ...
