这是因为对方屏蔽了你的地址（下载llama3出现ERROR 403: Forbidden解决方案_llama3 403-CSDN博客

需要不停的更换节点，一直到合适为止

下载后是.pth模型

转换为safetensors格式（hugging face版本）


import torch
from safetensors.torch import save_file

# 1. 加载 .pth 文件
pth_file_path = 'consolidated.00.pth'
model_state_dict = torch.load(pth_file_path)

# 2. 保存为 .safetensors 文件
safetensors_file_path = 'model.safetensors'
save_file(model_state_dict, safetensors_file_path)
