Yaml 如何正确使用文件中的“template”部分？

问题

我尝试使用

template

，在

mnist.yml

中添加

template

部分

我这样做是为了模仿下面的一个简短示例：

我的尝试在这里：（剩余的

mnist.yml

和

mnist defaults.yml

未被触及），mnist的原始文件将被删除

然后我得到了以下错误：

以下是对亚当回答的回应：

更新到kur 0.5.2后，代码如下，

mnist默认值。yml

未被触及：

mnist.yml：

---
include:
  - mnist-defaults.yml
  - mnist_cnn_helper.yml

settings:
  cnn:
    k: 64
    s: 2

model:
  - input: images
  # - convolution:
  #     kernels: 64
  #     size: [2, 2]
  - cnn_block: "{{cnn}}"
  - activation: relu
  - flatten:
  - dense: 10
  - activation: softmax
