Update model version with PaddleOCR

[er778899789]

I want to update the recognition model (ch_ppocr_mobile_v2.0_infer) in Paddle official github website.
The downloaded file look like below.

When change & rename with model file and params file in new version, I get the following error :

How can I change new version model in this project?

Sorry to tell you that I already shifted my research interest from this area. So it might be tricky for me, but it seems the new weight from Paddle is no longer compatible with old loading fashion. Wish other users could solve your problem.
