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.

Crash during Tagging when using word embedding #13

Closed bratao closed 8 years ago

bratao commented 8 years ago

Hello again @zhongkaifu ,

Testing the latest version, after training, if I try to tag a file, I get the following crash:

Without WORDEMBEDDING_FILENAME , it works nice. The emmbed was created in Tex2Vec with the following command line: Txt2VecConsole.exe -mode train -trainfile corpus.txt -modelfile vector.bin -vocabfile vocab.txt -vector-size 200 -window 5 -min-count 1 -cbow 1 -threads 1 -iter 15

Hi @bratao
From log, it seems word embedding context settings isn't loaded. could you please share configuration file ?

bratao commented 8 years ago

My bad, you´re right. I forgot to use the context setting in tagging !
