关于./scripts/single_gpu的训练参数保存问题（paddle-2.2.2）

[M-aterialism]

你好，我在使用./scripts/single_gpu/train.sh时，会报出

Traceback (most recent call last): File "./knover/scripts/train.py", line 250, in <module> train(args) File "./knover/scripts/train.py", line 170, in train save_model(model, args.save_path, "best", args) File "./knover/scripts/train.py", line 242, in save_model model.save(path, is_checkpoint=args.save_checkpoint) File "/home/aistudio/work/Knover/knover/core/model.py", line 541, in save paddle.save(self._dist_model.state_dict(), params_path) AttributeError: 'ModelInterface' object has no attribute '_dist_model'

的错误，而在使用./scripts/destributed/train.sh时，就不会出现，请问可以解决吗？

Knover/knover/core/model.py

Line 541 in 53d5b20

paddle.save(self._dist_model.state_dict(), params_path)

这里你先把改成 self._dist_model 改成 self._model 哈，我这边同步测试一下，会不会影响其他功能，测试没有问题的话加个 patch 修复一下

测试无问题，已经合入了，你拉最新代码就好哈
