How to run numpy module programs with gsoc-2024-dev pybind11

1. Prepare the python code file with the numpy operations you want to run. \ \ For example : let's try out numpy arange function in test_numpy.py

   import numpy_bindings as np
     
   def test_arange(n):
     a = np.arange(n)
     print(a.sum())
     
   test_arange(100)
   

2. Read the script and execute it in test_numpy.cpp.

   #include <pybind11/embed.h>
   #include <fstream>
   #include <sstream>
   #include <string>
     
   namespace py = pybind11;
   using namespace pybind11;
     
   int main() {
     py::scoped_interpreter guard{};
     std::ifstream file("test_numpy.py");
     std::stringstream buffer;
     buffer << file.rdbuf();
     std::string script = buffer.str();
     py::exec(script);
     
     return 0;
   }
   

3. Build the project at root to generate the executable at build/gsoc2024.

   cmake -B build
   cmake --build build
   

4. Now run the executable to get the output.
