A library to check if two complex/nested objects are equal or not
Project description
coola
Overview
coola is a Python library that provides simple functions to check in a single line if two
complex/nested objects are equal or not.
coola was initially designed to work
with PyTorch Tensors
and NumPy ndarray, but it
is possible to extend it
to support other data structures.
Motivation
Let's imagine you have the following dictionaries that contain both a PyTorch Tensor and a
NumPy ndarray.
You want to check if the two dictionaries are equal or not.
By default, Python does not provide an easy way to check if the two dictionaries are equal or not.
It is not possible to use the default equality operator == because it will raise an error.
The coola library was developed to fill this gap. coola provides a function objects_are_equal
that can indicate if two complex/nested objects are equal or not.
import numpy
import torch
from coola import objects_are_equal
data1 = {"torch": torch.ones(2, 3), "numpy": numpy.zeros((2, 3))}
data2 = {"torch": torch.zeros(2, 3), "numpy": numpy.ones((2, 3))}
objects_are_equal(data1, data2)
coola also provides a function objects_are_allclose that can indicate if two complex/nested
objects are equal within a tolerance or not.
from coola import objects_are_allclose
objects_are_allclose(data1, data2, atol=1e-6)
Please check the quickstart page to learn more on
how to use coola.
Installation
We highly recommend installing
a virtual environment.
coola can be installed from pip using the following command:
pip install coola
To make the package as slim as possible, only the minimal packages required to use coola are
installed.
To include all the packages, you can use the following command:
pip install coola[all]
Please check the get started page to see how to install only some specific packages or other alternatives to install the library.
Contributing
Please check the instructions in CONTRIBUTING.md.
API stability
:warning: While coola is in development stage, no API is guaranteed to be stable from one
release to the next.
In fact, it is very likely that the API will change multiple times before a stable 1.0.0 release.
In practice, this means that upgrading coola to a new version will possibly break any code that
was using the old version of coola.
