Coupling Openfoam solver and keras trained neutral network model
Hello,
I try to couple simpleFoam solver and keras neutral network trained model.
Anyone have an idea to do so?
the following link suggest to use frugally-deep header library or #include <Python.h>
https://www.researchgate.net/publica...itutive_models
I installed frugally-deep and check it is working with ordinary C++ program
However when I try to implement the same in OpenFoam I got compilation error.
Anyone have an idea how to utilize frugally-deep in openFoam or even have an alternative way to use keras trained model.
below is added code to simpleFoam and the error
Code:
...........................
#include <fdeep/fdeep.hpp>
int main(int argc, char *argv[])
{
.........................
const auto model = fdeep::load_model("fdeep_model.json");
const auto result = model.predict(
{fdeep::tensor(fdeep::tensor_shape(static_cast<std::size_t>(4)),
std::vector<float>{1, 2, 3, 4})});
std::cout << fdeep::show_tensors(result) << std::endl;
..........................
}
The error
