In MT DATASET i have successfully pretrained my model.Now i move to train my model
I execute the command :

th bso_train.lua -data_file data_prep/MT/prep-train.hdf5 -val_data_file data_prep/MT/prep-val.hdf5 -savefile mixersave -num_layers 1 -rnn_size 4 -word_vec_size 4 -save_after 21 -adagrad -curriculum 0 -epochs 21 -train_from mixerpt_epoch3_*.t7 -dropout 0.2 -max_beam_size 6 -beam_size 2 -layer_etas 0.02,0.02,0.1 -mt_delt_multiple 1

but it shows error

How can i fix it ? pls help

When i write the command
java -cp stanford-parser-3.3.0.jar edu.stanford.nlp.trees.EnglishGrammaticalStructure -treeFile ~/Projects/group/data/wsj/train.txt -conllx -basic > train.conll.txt ( the first one for Creating the Dependency Parsing Dataset)
i get the error
Error: Could not find or load main class edu.stanford.nlp.trees.EnglishGrammaticalStructure

i have searched this error but i am unable to resolve it and proceed further
