How to finetune pretrain file

[chaiwitl]

Hi,

I just start on EasyOCR. I would like to finetune on top pretrain file (thai.pth) by using trainer.ipynb.
During train this file the validation result was accurate. After finish train script, I have applied the *.pth from training to c:\Users<username>.EasyOCR\model and initial EasyOCR by using recog_network='' but the result is not accurate (not same).

Have anyone suggest me my method is correct or not. And Why the result during validate in training and during applied finetune file is not the same accurate level?
