transformers 加载模型时报错

transformers加载模型时报错

安装transformers后，拿下面的代码测试：

from transformers import AutoTokenizer, TFAutoModel
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
model = TFAutoModel.from_pretrained("bert-base-uncased")
inputs = tokenizer("Hello world!", return_tensors="tf")
outputs = model(inputs)
print(inputs)
print(outputs)

报错：

原因
加载模型需要翻墙。
