Hi!

As far as I know, the most common cause of this problem comes from missing some key files when downloading the model from Hugging Face.

Ensure you've downloaded all the files from codes-7b-merged and subsequently placed them into the /mnt/disk3/home/ls/project/text2sql-demo/model/seeklhy/codes directory.

ok，I redownloaded the model and now it works！but，I checked the SHA256 of the model I downloaded before and it is the same and Its location is no problem either。
