Question

I install Fast Artificial Neural Network Library in Python 3.7:

pip install fann2

Exception:

Answer 1

Installation from source on Windows:

• Install Visual C++ Build Tools;
• Install FANN source code, using cmake;
• Copy "fanndouble.lib" from FANN installed files to ${python_libs_directory} as "doublefann.lib";
• Install swig for Windows (you will need to set an Enviroment Variable for "swig.exe");
• Run > python setup.py install from PowerShell/Command Prompt.

Answer 2

Install Windows prebuilt package:

pip3 install pipwin
pipwin install fann2

This is equivalent to downloading and installing the package from archive.
