torch和torchvision版本匹配了但是报错module 'torch.jit' has no attribute '_script_if_tracing'

######pytorch和torchvision版本问题

######我安装的版本已经是对应好的并且import也没问题 但是还是会报错

@torch.jit._script_if_tracing
AttributeError: module 'torch.jit' has no attribute '_script_if_tracing'

我的CUDA是10.0，torch版本1.1.0，torchvision版本是0.3.0

看下项目的要求版本是多少
