AttributeError: module 'paddle' has no attribute 'fluid'

[WintersMontagne10335]

可能是因为paddle develop分支中fluid已经废弃了，但是benchmark中没有做出相应的调整

I think PaddlePaddle/PaddleOCR#13280 provides an answer to this question.
In particular, PaddlePaddle/PaddleOCR#10333 removed fluid.

Updating the version of paddle should solve the issue.
