安装割炬时如下：

git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;

在这一步：

   bash install-deps

安装正确完成。但是我收到一条我不明白的消息。

  OS               ... Linux             
  Architecture     ... x86_64               
  BINARY           ... 64bit                 
  C compiler       ... GCC  (command line : gcc)
  Fortran compiler ... GFORTRAN  (command line : gfortran)
  Library Name     ... libopenblas_haswellp-r0.2.20.dev.a (Multi threaded; Max num-threads is 8)

 Use OpenMP in the multithreading. Because of ignoring OPENBLAS_NUM_THREADS and GOTO_NUM_THREADS flags, 
 you should use OMP_NUM_THREADS environment variable to control the number of threads.



To install the library, you can run "make PREFIX=/path/to/your/installation install".

make -j 8 -f Makefile.install install
make[1]: Entering directory '/tmp/OpenBLAS'

Install OK!
make[1]: Leaving directory '/tmp/OpenBLAS'
==> Torch7's dependencies have been installed

我不明白这一行：

To install the library, you can run "make PREFIX=/path/to/your/installation install".

要安装什么库以及如何安装？

运行前：

./install.sh

此行是 OpenBLAS 安装的输出，我认为它是 Torch 的依赖项。

该声明说您可以更改OpenBLAS的默认安装路径，但在下一行： make -j 8 -f Makefile.install install 它正在安装库，您可以在它之后看到安装输出。

所以你不需要做任何事情。
