发现了cntk 2.0 rnn方面的一个bug

 SimpleNetworkBuilder里面设置SIMPLERNN RnnType. 会有一个崩溃

要改正需要修改相关代码

SimpleNetworkBuilder.cpp:174

ComputationNetworkPtr SimpleNetworkBuilder::BuildRNNFromDescription()

{

ComputationNetworkBuilder builder(*m_net);

if (m_net->GetTotalNumberOfNodes() < 1) // not built yet

{

unsigned long randomSeed = 1;

size_t numHiddenLayers = m_layerSizes.size() - 2;

size_t numRecurrentLayers = m_recurrentLayers.size();

ComputationNodePtr input, w, b, u, pastValue, output, label, prior;

//add by ljh
if (m_sparse_input)
input = builder.CreateSparseInputNode(L"features", m_layerSizes[0]);
else
input = builder.CreateInputNode(L"features", m_layerSizes[0]);

//input = builder.CreateSparseInputNode(L"features", m_layerSizes[0]);

这是我在github上的回答
