在使用torch.hub的时候，无法加载模型，错误提示：cannot import name 'QuantStub' from 'torch.ao.quantization'

Question

代码：model = torch.hub.load('pytorch/vision', 'deeplabv3_resnet101', pretrained=True)
报错：ImportError: cannot import name 'QuantStub' from 'torch.ao.quantization' (/home/suned/anaconda3/envs/pytorch/lib/python3.8/site-packages/torch/ao/quantization/init.py)
