Initializing weights from checkpoint with configs - init_from_ptl_ckpt

[stalevna]

Describe the bug
Hi! When I tried to initialize weights of the model from checkpoint using configs and excluding some parts of it I get an error that model_path is not defined
I looked a the code at https://github.com/NVIDIA/NeMo/blob/main/nemo/core/classes/modelPT.py and indeed there is an initialized variable ckpt_path, but model_path is initialized for init_from_nemo_model

Could you check if it was just accidental copy-paste and there should be ckpt_path instead of model_path
self.load_part_of_state_dict(
ckpt['state_dict'], include, exclude, f'nemo file with path **{model_path**}'
)

in this snippet of the code

    if 'init_from_ptl_ckpt' in cfg and cfg.init_from_ptl_ckpt is not None:
        with open_dict(cfg):
            if isinstance(cfg.init_from_ptl_ckpt, str):
                # Restore checkpoint
                ckpt_path = cfg.pop('init_from_ptl_ckpt')
                ckpt = torch.load(ckpt_path, map_location=map_location)

                # Restore checkpoint into current model
                self.load_state_dict(ckpt['state_dict'], strict=False)
                logging.info(
                    f'Model checkpoint restored from pytorch lightning chackpoint with path : `{ckpt_path}`'
                )

                del ckpt
            elif isinstance(cfg.init_from_ptl_ckpt, (DictConfig, dict)):
                model_load_dict = cfg.init_from_ptl_ckpt
                for model_load_cfg in model_load_dict.values():
                    ckpt_path = model_load_cfg.path
                    # Restore model
                    ckpt = torch.load(ckpt_path, map_location=map_location)

                    include = model_load_cfg.pop('include', [""])
                    exclude = model_load_cfg.pop('exclude', [])

                    self.load_part_of_state_dict(
                        ckpt['state_dict'], include, exclude, f'nemo file with path `{model_path}`'
                    )
