I'm using coremltools neural_network to build a model implement ssd-caffe detection out layer Detail imformation is here:https://github.com/apple/coremltools/issues/879 MLModel::compileModelAtURL compile error message is too vague. cannot find out whats going wrong. Is there any way show model compile verbose message
