我试图在铁轨项目中使用范例（快速人工神经网络）库。因此，我已经安装了风扇（安装似乎还可以，我在线遵循了一些指南）。另外，我已经在我的Gemfile中添加了ruby-fann GEM，并且已安装。但是，当我运行rspec以测试我的代码时，我会收到一个很长的错误，该错误具有以下开始：
/app/models/neural_network.rb:12: [BUG] Segmentation fault at 0x00000000000009
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

Abort trap: 6
/app/models/neural_network.rb:12行上的代码是
train = RubyFann::TrainData.new(inputs: inputs, desired_outputs: desired_outputs)
我解决了我的问题。我传递给rubyfann :: traindata.new没有所需类型的论点之一。
