Question

我正在尝试对具有3个输入节点，具有4个节点的隐藏层和1个输出节点的神经网络进行编码。（这将在最终版本中有所变化，因此我将它们转换为变量。）即使我已将代码与教程进行了比较，并且看不到任何错误，但是当我尝试运行它时，它给我一个ValueError，说它不能对这些数组进行点乘。

这是我的第一个使用NumPy的项目，所以我对应该做的事情一无所知。

这是我的代码：

  "version": "0.1.0",
  "private": true,
  "devDependencies": {

    "react-navigation": "3.0.4",
    "web3": "1.0.0-beta.34",
    "yup": "^0.26.6"
  }
}

我希望程序至少可以运行，但是它给我以下错误：

我发现了我的问题：我正在倒退l1_error的点积！

l1_error = np.dot(l2_nudge, syn1.T)
