Python

It was programmed with 3.10.4. And I used some 3.10 Python expression. Thus you might get problems with older Python versions.

C++

You need to modify the Makefile in the C++ directory to your Python installation.

In addition your Python installation needs the PyBind11 package installed. You might want to perform a
pip install pybind11
The Makefile uses clang as a compiler. If you want something else then you need to change the Makefile. For CUDA I used version 12.0.

Config files and pre-existing weights

Three .json config files are required:

dataset.json : Information about the dataset

network.json : Describes the network architecture

def.json : Controlls the other parameters

If you want to load existing weights, just put them in a sub-folder called Previous
