## Setup

Check include file in `py_wrapper.hpp` & `solver.hpp` (python version)

```

#include "/usr/include/python3.6m/Python.h"

#include "/usr/include/python3.6m/numpy/arrayobject.h"

#include "/usr/include/python3.6m/numpy/arrayscalars.h"

```

If there exist no files in `/usr/include/python3.6m`, type commands as follows:

```

sudo apt-get install python3-dev

sudo apt-get install python3-numpy

```

(sudo) rm -rf build

(sudo) pip3 uninstall mySolverModule

Type command as follows:

```

sudo python3 setup.py install

```

To confirm, type `pip3 freeze`. `mySolverModule==1.0.0` will be listed.

[Uninstall]

```

sudo rm -rf build

sudo pip3 uninstall mySolverModule

```

## Run

```

python3 main.py -p input-Q-file(.txt) [-s seed-value] [-o output-A-file(.txt)]

```
