nnue-probe is library for probing NNUE neural networks for chess. The core nnue probing code is taken from CFish and modified a bit.
To compile
make clean; make COMP=gcc
Cross-compiling for windows from linux using mingw is possible by setting COMP=win
from __future__ import print_function
from ctypes import *
nnue = cdll.LoadLibrary("libnnueprobe.so")
nnue.nnue_init(b"nn-04cf2b4ed1da.nnue")
score = nnue.nnue_evaluate_fen(b"rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1")
print("Score = ", score)
The result
Loading NNUE : nn-04cf2b4ed1da.nnue
NNUE loaded !
Score = 42
