   Sorry for that, in previous situation, we confronted the situation that element of input data is close to zero.
   And we found that the extremely big  difference step, eps, should be blamed. And we turned its value down. However, in current situation, test failure is caused by the small eps for the big  element of  input data.  The smaller the eps is, more calculation steps is required. And for big input data, every step could cause small error and finally the cumulative error may exceed the limit. Thus, suitable eps should be picked. 
   
   After all, those problems are caused by the inaccurate baseline calculation referring to the theano gradient. We are trying to rewrite the test case with other approaches. I suggest to disable the flaky test for the time being.
