ZeroDivisionError: division by zero

Hi, when I run the command ,I meet the problem ./mpi-train.sh 10 Instances file: /users4/xyan/experiment/phrase/phrase_vec_embedding/str2vec-master/demo-data/str2vec-demo/input/sample-training-file.txt Model file: /users4/xyan/experiment/phrase/phrase_vec_embedding/str2vec-master/demo-data/str2vec-demo/output/sample-training-file.mpi-10.model.gz Word vector file: /users4/xyan/experiment/phrase/phrase_vec_embedding/str2vec-master/demo-data/str2vec-demo/input/sample-word-vectors-trained-by-word2vec.txt lambda_reg: 0.149999999999999994 Max iterations: 200

I don't know what cause this eror?Can you help me, thanks!
