Migrate to numpy 2.0

[cclauss]

Feature description

The beta release of numpy is now available so we should run the appropriate ruff command and ensure our algorithms are compatible... https://numpy.org/devdocs/numpy_2_0_migration_guide.html

@cclauss I think this rule is already checked and satisfied.

Command

ruff check --select NPY201

does not show any violations.

And in https://docs.astral.sh/ruff/rules/#numpy-specific-rules-npy I do not see any specific signs near NPY201 rule to believe that it is not included by default in https://github.com/TheAlgorithms/Python/blob/master/pyproject.toml#L48

[cclauss]

Are there other tasks required to complete the upgrade?

[MaximSmolskiy]

As I understand, experiment in #11340 shows that some packages (statsmodels, scikit-learn and maybe some more) are not ready for numpy 2.0 - there are problems on Install dependencies stage

I truly wish you a good luck

[quant12345]

In which folder were the problems or show how to run all tests? I want to see what the problems are. In June I did a PR in statsmodels, they had one build numpy version --- 2.1.0.dev0 and there were no failures. I don't know about the current time.

[cclauss]

python3.12 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip setuptools six wheel
python -m pip install pytest-cov -r requirements.txt
pytest

From .github/workflows/build.yml

[quant12345]

After installation: pip install 'numpy==2.0.1' --force-reinstall

I receive the following warnings:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
imageio 2.35.0 requires numpy<2.0.0, but you have numpy 2.0.1 which is incompatible.
tensorflow 2.17.0 requires numpy<2.0.0,>=1.26.0; python_version >= "3.12", but you have numpy 2.0.1 which is incompatible.

There are a few files where the tests fail, but there are no errors, and the following is printed:

Extension modules: numpy._core._multiarray_umath, numpy._core._multiarray_tests, numpy.linalg._umath_linalg (total: 3)

Invalid instruction (memory image flushed to disk)

Files in which tests do not run(numpy 2.0.1):
computer_vision/cnn_classification.py, dynamic_programming/k_means_clustering_tensorflow.py, machine_learning/lstm, machine_learning/sequential_minimum_optimization.py, neural_network/input_data.py.

Usually there is tensorflow there(I'm not exactly sure, but I'll assume that the reason is tensorflow).
There's something on the topic here.

And there are many test failures where numbers do not match when printed in the new numpy (the number is printed with the type).

Example: pytest electronics/circular_convolution.py

FAILURES:

Expected:
    [10, 10, 6, 14]
Got:
    [np.int64(10), np.int64(10), np.int64(6), np.int64(14)]

I can fix it (this does not apply to the five files I listed above):

1. Either convert numbers, arrays to Python instead of numpy.
2. Fix the tests themselves: 12.0 by replacing with np.float64(12.0)
3. You can put np.set_printoptions(legacy="1.25") .

Thoughts?

[cclauss]

My vote would be 1. convert numbers, arrays to Python instead of numpy.

v2.1.0 was just released https://pypi.org/project/numpy/#history

[quant12345]

Unable to launch: 'Getting requirements to build wheel did not run successfully'. I see a line with statsmodels. Although in their requirements.txt: numpy>=1.22.3,<3 .

I tried to return numpy-1.26.4 to requirements.txt, it works. In general, it is not clear yet what to do.?

Update 20.08.2024

So I found the ecosystem numpy 2.0 table. Judging by it, keras and tensorflow are not marked in it.
Also not: beautifulsoup4, fake_useragent, lxml, pillow, qiskit, qiskit-aer, requests, rich, tweepy, typing_extensions.

Last thing I tried: numpy>=2.0.0, matplotlib>=3.8.4, opencv-python>=4.10.0.84, pandas>=2.2.2, scikit-learn>=1.4.2, statsmodels>=0.14.2. Which didn't work.

sir please assign me this task i would work on it
