IndexError: invalid index to scalar variable.

为了提取网络层每一层的名称，源代码：

import cv2
layersNames = net.getLayerNames()
output_layers_names = [layersNames[i[0]- 1] for i in net.getUnconnectedOutLayers()]

报错信息：

根据提示应该是无效的索引，因为是opencv下，考虑到版本问题，将[i[0]-1]改为[i-1]

output_layers_names = [layersNames[i- 1] for i in net.getUnconnectedOutLayers()]

运行成功
