我在 Chaquopy android studio 项目中的 python 代码：

import torch as tc
from transformers import GPT2Tokenizer, GPT2Model



def generate_text(txt):
    """
    Generate chat
    https://huggingface.co/gpt2
    """

    #Load Model files
    tokenizer = GPT2Tokenizer.from_pretrained('assets/') #This line causing error
    model = GPT2Model.from_pretrained('assets/')
    #Move moel to GPU if avilable
    device = tc.device("cuda" if tc.cuda.is_available() else "cpu")
    model.to(device)

    encoded_input = tokenizer(txt, return_tensors='pt')
    output = model(**encoded_input)

    return str(output)

现在它显示以下错误：
