Pig Solver

This is a simple deep learning framework, which does not rely on a third-party library. If you need to use efficient numerical calculation, openblas is the only third-party library that needs to be installed.

Install OpenBLAS

If you want to speed up running , you need to install OpenBLAS, a third-party dependency.

1. Install OpenBLAS on MacOS

brew install openblas

2. Install OpenBLAS on Linux

In this part, we take the Linux system of Debian as an example.

# 1. Check your gfortran tool.
$ gfortran -v
If prompting command does not exist, you need to install it.
# 2. Install gfortran
$ mkdir your_software_install_path/opt/gfortran/
$ cd your_software_install_path/opt/gfortran/
$ wget https://gfortran.meteodat.ch/download/x86_64/releases/gcc-4.8.5.tar.xz 
$ xz -d gcc-4.8.5.tar.xz
$ tar -xvf gcc-4.8.5.tar
vim ~/.bashrc
export LD_LIBRARY_PATH=your_software_install_path/opt/gfortran/gcc-4.8.5/lib64:your_software_install_path/opt/gfortran/gcc-4.8.5/lib:$LD_LIBRARY_PATH
export PATH=your_software_install_path/opt/gfortran/gcc-4.8.5/bin:$PATH
source ~/.bashrc
# 3. Install OpenBLAS
$ git clone https://github.com/xianyi/OpenBLAS.git
$ cd OpenBLAS
$ make FC=gfortran -j 8
$ sudo make PREFIX=your_software_install_path/opt/OpenBLAS install
