特征张量编译误差

Question

我正在使用Eigen::Tensor进行实验，我无法理解为什么最基本的示例失败。为什么这件代码

#include <unsupported/Eigen/CXX11/Tensor>
int main()
{
    Eigen::Tensor<int, 2> a(4, 4);
    Eigen::Tensor<int, 2> b(4, 4);
    a.setRandom();
    b.setRandom();
    a += b;
    return 0;
}

导致错误：

In file included from eigen.cpp:2:
In file included from /usr/local/include/eigen3/unsupported/Eigen/CXX11/Tensor:142:
/usr/local/include/eigen3/unsupported/Eigen/CXX11/src/Tensor/TensorStorage.h:39:7: error: class template partial specialization is not

请更新到默认分支(推荐用于张量模块(，或者至少至3.3分支的头。
