Week 7

Mid-term evaluation approaching …. Hello everyone, hope this blog finds you well.

This week was indeed a heavy week as far as project planning and code discussion was concerned. I managed to submit requested code submissions before the deadline and my mentor @blueloveTH was satisfied with the work.

Aim :

My aim for this week was to get my code compatible with pocketpy pybind and prepare a wokring demo for my mentors.

Work :

This is the demo I prepared for my mentors. The frontend is at a basic stage but that will be improved as soon as the backend is ready.

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

Prepare a python code file with the numpy operations you want to run.
For example : Let’s try 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)

Read the script and execute it in test_main.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;
    }

Build the project at root to generate the executable at build/gsoc2024.
```
    cmake -B build
    cmake --build build
```

Now run the executable to get the output.

I made the following pull requests this week -

PR#30 : Refactor some functions into properties

The pull request makes dtype, ndim, shape, size as readonly properties instead of member functions. I had to use the def_readonly_property label from pybind11 to ensure it.

PR#31 : Make print inline with numpy

The pull request fixes the following bug -

>>> a = np.array([1, 2, 3])
>>> a

# cpython's numpy
array([1, 2, 3])

# ours
ndarray(
{1, 2, 3}
)

PR#32 : Remove xoptional headers
PR#33 : Removed unrequired data convertors
PR#34 : Remove xjson from xtl headers as well

Future Work :

In this upcoming week, we will start work after the mid term evaluation. I am pretty confident that I will pass this evaluation. Following that we need to reduce disk space required for the project and start working on all the numpy dtypes.
