some question on SentEval tools

[nutshell999]

Hello! My friend.
I am trying to reproduce the HBMP model(trained on SNLI) on SentEval tool.But i found my result(83.15%) is always 1.0-1.5% lower than the state of the art 84.6% on CR from Conneau's paper. And the result on MR is the same. other settings on model, code are same with your paper.
Here are some details：
1.results(just compared to Infersent)
Infersent results from anthors'paper: CR(84.6%), MR(79.9%) (on SNLI)
HBMP(on SNLI) reproduced results :

2.My senteval settings:
params_senteval = {'task_path': PATH_TRANSFER_TASKS, 'usepytorch': True, 'kfold': 10}
params_senteval['classifier'] = {'nhid': 0, 'optim': 'adam,lr=0.01', 'batch_size': 64,
'tenacity': 5, 'epoch_size': 4}

How could i do for reproducing the results from paper?
change the senteval settings?
