zhongkaifu / RNNSharp

RNNSharp is a toolkit of deep recurrent neural network which is widely used for many different kinds of tasks, such as sequence labeling, sequence-to-sequence and so on. It's written by C# language and based on .NET framework 4.6 or above versions. RNNSharp supports many different types of networks, such as forward and bi-directional network, sequence-to-sequence network, and different types of layers, such as LSTM, Softmax, sampled Softmax and others.

Hello! After the last update, I get this error:

before update it is working without problems.

My config is :

`CURRENT_DIRECTORY = .\model2cfg

MODEL_TYPE = SEQLABEL

Forward and BiDirectional are supported

NETWORK_TYPE = Forward

MODEL_FILEPATH = model.bin

HIDDEN_LAYER = LSTM:200, LSTM:100

OUTPUT_LAYER = Simple

CRF_LAYER = True

TFEATURE_FILENAME = tfeatures

Binary and Freq are supported

TFEATURE_WEIGHT_TYPE = Freq

TFEATURE_CONTEXT = -7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5

PRETRAIN_TYPE = Embedding

WORDEMBEDDING_FILENAME = vector_big.bin

WORDEMBEDDING_CONTEXT = -1,0,1

WORDEMBEDDING_COLUMN = 0

AUTOENCODER_CONFIG = D:\RNNSharpDemoPackage\config_autoencoder.txt

SEQ2SEQ_AUTOENCODER_CONFIG: D:\RNNSharpDemoPackage\config_seq2seq_autoencoder.txt

RTFEATURE_CONTEXT = -2,-1`

This happens after 47 iterations...
