报错 代码片.

import timm

model = timm.create_model('res2net101_26w_4s', pretrained=True)
print(model)

大概就是因为网络请求错误问题啥的
timm他会默认先从huggingfaceHub下载，但是HF现在又被墙了，所以要手动下载

1、先获取cfg信息

import timm
model = timm.create_model('res2net101_26w_4s')
print(model.default_cfg)

在这里插入图片描述

2.【科学上网】去https://huggingface.co/上搜索然后再下载模型
在这里插入图片描述
3.下载保存到项目路径下
alt
4、添加参数，再次运行成功打印模型

import timm

model = timm.create_model('res2net101_26w_4s', pretrained=True,
                          pretrained_cfg_overlay=dict(file='checkpoint/res2net101_26w_4s/pytorch_model.bin'))
print(model)
