[BUG] ValueError issues during testing changes #725
Description
Activity
hi!
I’m interested in investigating this issue and trying to reproduce it locally.
I’ll look into howpytest-randomlyinteracts with seed generation and update here if I find the root cause or open a PR.I've put together a fix for this. The root cause is that older versions of
pytest-randomlycan generate seeds exceeding numpy's2**32 - 1limit fornumpy.random.seed().The fix adds a
tests/conftest.pythat wrapsnumpy.random.seedto constrain integer seeds via modulo. It's minimal - no library code changes, just a test-scoped patch.I've also added
tests/test_conftest.pywith 7 tests covering boundary cases, None seeds, and determinism preservation.Opening a PR now.
Describe the bug
When running tests the random seed generation is causing trouble
ValueError: Seed must be between 0 and 2**32 - 1Also it's not for the new test I am adding for #723 , I tested multiple other tests and this issue is same throughout.Expected behavior
It should be properly generating seeds under a certain range as described in this issue.
Code sample
If you've setup the repository
Operating system, python version, PyPortfolioOpt version
Windows 11, python@latest, PyPortfolioOpt@latest
Additional context
It's working when tried to run using
pytest test/<test-file-name> -p no:randomlyAs
-p no:randomlystops it to generate seeds randomlyProof:
As of now I don't know how to fix it, but will understand and solve the issue and submit a PR, if anyone else' have expertise please feel free to open a PR!!
