Question

我一直试图在完全卷积神经网络的基础上试验这个semantic segmentation code。但是，运行此代码会生成由

引起的以下错误消息

fcn32model = fcn32_blank(image_size)

我没有更改代码中的任何内容，并且对于导致此错误的原因感到困惑。

Using Theano backend.

TypeError: index must be integers

Answer 1

将其转换为int：

(int(extra_margin/2), int(extra_margin/2))

Typeerror的错误消息：index必须是整数
