在做推断时候发生错误，前面样本推断得都没问题，到了中间某个样本就出现了这个，把那个样本删除掉还是同样的错误。

paddle.fluid.core.EnforceNotMet: Enforce failed. Expected begin_idx < end_idx, but received begin_idx:309 >= end_idx:309.
The start row index must be lesser than the end row index. at [/home/tangjian/paddle-release-docer/paddle/fluid/framework/tensor.cc:95]
