Thanks for your great work！ The previous issue has been solved， but I find a new issue. If I change the code (https://github.com/KaiyangZhou/CoOp/blob/ff61507c790454bce7c5052c3ac39e60772f1f89/trainers/coop.py#L248) as self.register_model("model", self.model, self.optim, self.sched). The result will drop considerably(20%)！ Can you give me some advice?
