Question

我尝试构建FRNN的模型：

for i, owa_weights, k in [(1, strict(), 1), (2, additive(), 20)]:
  # Create an instance of the FRNN classifier, construct the model, and query on the test set.
  clf = FRNN(nn_search=nn_search, upper_weights=owa_weights, lower_weights=owa_weights, lower_k=k, upper_k=k)
  cl = clf.construct(X_train, y)
  scores = model(X_test)

但我收到一个错误：

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)

      7   # Create an instance of the FRNN classifier, construct the model, and query on the test set.
      8   clf = FRNN(nn_search=nn_search, upper_weights=owa_weights, lower_weights=owa_weights, lower_k=k, upper_k=k)
----> 9   cl = clf.construct(X_train, y)
     10   scores = model(X_test)

IndexError: index 73922 is out of bounds for axis 0 with size 73920

X_train 的形状是 (73920,300) 然后我试着像这样运行：

cl = clf.construct(X_train[-2:73920], y)

但我收到一个错误：

IndexError: index 49 is out of bounds for axis 0 with size 2
