Torch - 错误getrf : Lapack library not found in compile time 解决

安装编译OpenBLAS：

git clone https://github.com/xianyi/OpenBLAS.git
cd OpenBLAS
make NO_AFFINITY=1 USE_OPENMP=1
sudo make install

安装成功后，luarocks install torch 可能找不到OpenBLAS，需要定义路径再进行torch安装：

CMAKE_LIBRARY_PATH=/opt/OpenBLAS/include:/opt/OpenBLAS/lib:$CMAKE_LIBRARY_PATH luarocks install torch

测试实例：

-- choose a dimension
N = 5

-- create a random NxN matrix
A = torch.rand(N, N)

-- test 
AI = torch.inverse(A) -- 该错误出现的地方
