KeyError 训练值

Question

当运行下面的代码 sn-p 时，我收到一个错误，在我未经训练的眼睛看来一切都是正确的。我试图找出错误在哪里无济于事。

Training Model KeyError

# Specify arrays with input feature values
trainX = train[list(train)[1:]].values # numpy array with training inputs
testX = test[list(train)[1:]].values # numpy array with test inputs

# Specify arrays with output value labels
trainY = train.label.values #output labels for training examples
testY = test.label.values # output labels for test examples

# Show dimensions for arrays
print('Train on %d labeled observations with %d input features.' 
%trainX.shape)
print('Test on %d labeled observations with %d input features' 
%testX.shape)`

错误：

    KeyError                                  Traceback (most recent call 
last)
<ipython-input-66-0e3d6e12b557> in <module>()

inputs
----> 2 testX = test[list(train)[1:]].values # numpy array with test 
inputs
  3 
  4 # Specify arrays with output value labels
  5 trainY = train.label.values #output labels for training examples

Answer 1

输入文件和变量不正确
