Where does transformers save microsoft/DialoGPT-small?

Question

when I run the code

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
SML=input("small,medium or large: ").lower()#I pick small
model_name = "microsoft/DialoGPT-"+SML
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

It downloads microsoft/DialoGPT-small from somewhere on the internet and downloads it to my computer but I don`t know where the saved file is. Anyone have any idea where this file is saved?

#EDIT#

I found the below code in \Lib\site-packages\transformers\models\dialogpt\convert_dialogpt_original_pytorch_checkpoint_to_pytorch.py but have no idea what it means.

def convert_dialogpt_checkpoint(checkpoint_path: str, pytorch_dump_folder_path: str):
    d = torch.load(checkpoint_path)
    d[NEW_KEY] = d.pop(OLD_KEY)
    os.makedirs(pytorch_dump_folder_path, exist_ok=True)
    torch.save(d, os.path.join(pytorch_dump_folder_path, WEIGHTS_NAME))

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("--dialogpt_path", default=".", type=str)
    args = parser.parse_args()
    for MODEL in DIALOGPT_MODELS:
        checkpoint_path = os.path.join(args.dialogpt_path, f"{MODEL}_ft.pkl")
        pytorch_dump_folder_path = f"./DialoGPT-{MODEL}"
        convert_dialogpt_checkpoint(
            checkpoint_path,
            pytorch_dump_folder_path,
        )
