RuntimeError: dimension specified as 0 but tensor has no dimensions解决

错误代码：

if __name__ == '__main__':

    data=torch.tensor(3.1416)
    print(data.size(0))

网友解决方法：

如果是数据不对，数据前面加一个[]扩起来就有size了

print( torch.tensor([3.1416]).size(0))

如果数据源不可控，我的解决方法：

    data=torch.tensor(3.1416)

    if (data.size() != torch.Size([])):
        print(data.size(0))

    data=torch.tensor([3.1416])

    if (data.size() != torch.Size([])):
        print(data.size(0))
