Question

运行涉及以下函数的python程序时，image[x,y] = 0会显示以下错误消息。这意味着什么以及如何解决它？感谢。

警告

VisibleDeprecationWarning: using a non-integer number instead of an integer   
will result in an error in the future
image[x,y] = 0
Illegal instruction (core dumped)

代码

def create_image_and_label(nx,ny):
  x = np.floor(np.random.rand(1)[0]*nx)
  y = np.floor(np.random.rand(1)[0]*ny)

  image = np.ones((nx,ny))
  label = np.ones((nx,ny))
  image[x,y] = 0
  image_distance = ndimage.morphology.distance_transform_edt(image)

  r = np.random.rand(1)[0]*(r_max-r_min)+r_min
  plateau = np.random.rand(1)[0]*(plateau_max-plateau_min)+plateau_min

  label[image_distance <= r] = 0 
  label[image_distance > r] = 1
  label = (1 - label)

  image_distance[image_distance <= r] = 0 
  image_distance[image_distance > r] = 1
  image_distance = (1 - image_distance)*plateau

  image = image_distance + np.random.randn(nx,ny)/sigma

  return image, label[92:nx-92,92:nx-92]

警告说不要使用浮点数来索引数组;使用np.int代替np.floor
