Error message: "ValueError: The checkpoint file does not exist."

I am trying to implement FastRCNN using Mindspore, I am using the code from the offciel gitee as a reference: 'https://gitee.com/mindspore/mindspore/tree/r1.3/model_zoo/official/cv/faster_rcnn'

knowint that I am using Mindspore 1.3 

and VOC dataset. 

When I run the train.py code the following error pop up: 

Traceback (most recent call last):
  File "C:/Users/Yaman/PycharmProjects/MindSpore_1.3/train_New.py", line 114, in <module>
    param_dict = load_checkpoint(load_path)
  File "C:\Users\Yaman\AppData\Local\Programs\Python\Python37\lib\site-packages\mindspore\train\serialization.py", line 401, in load_checkpoint
    ckpt_file_name, filter_prefix = _check_checkpoint_param(ckpt_file_name, filter_prefix)
  File "C:\Users\Yaman\AppData\Local\Programs\Python\Python37\lib\site-packages\mindspore\train\serialization.py", line 478, in _check_checkpoint_param
    raise ValueError("The checkpoint file does not exist.")
    ValueError: The checkpoint file does not exist.

This is the line of code causing the error:

load_path = config.pre_trained
if load_path != "":
    param_dict = load_checkpoint(load_path)

And this is what I have in Config: 

pre_trained: "/cache/train/fasterrcnn/faster_rcnn-12_7393.ckpt"

Why I cant find the above file, do I have to creat the checkpoint file (faster_rcnn-12_7393) or I have to download from somewhere? 

Thank you in advance,,
