Description

为paddle.max、paddle.min支持 指定axis为非零轴的0-size tensor输入。
以numpy为例

data = np.random.random([0, 2, 3])
res = np.max(data, axis)
  1. axis = (0, )
ValueError: zero-size array to reduction operation maximum which has no identity
  1. 指定 axis = (1, ), keepdims = False
shape:(0, 3), val: []
  1. 指定 axis = (2, ), keepdims = False
shape:(0, 2), val: []
  1. 指定 axis = (1, 2), keepdims = False
shape:(0,), val: []
  1. 指定axis = (2, ), keepdims = True
shape:(0, 2, 1), val: []
  1. 指定axis = (1, ), keepdims = True
shape:(0, 1, 3), val: []
