AttributeError: module 'numpy' has no attribute 'int'.

[notuntoward]

When I run this:

boruta.fit(Xtrn, yTrn)

I get the error message below, indicating that boruta_py isn't compatible with numpy versions greater than 1.20. I had numpy version 1.24.2 installed. So I ran:

conda install "numpy<1.20"

and then I no longer got this error from Boruta. However, reverting to numpy<1.20 cost at least an hour of redoing my configuration of other packages.

A fix for this problem would be very helpful.

The error message

AttributeError: module 'numpy' has no attribute 'int'.
np.int was a deprecated alias for the builtin int. To avoid this error in existing code, use int by itself. Doing this will not modify any behavior and is safe. When replacing np.int, you may wish to use e.g. np.int64 or np.int32 to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

I had the same problem. I do not know if it helps you @notuntoward but I succesfully used BorutaPy with numpy==1.23.5.
(numpy.int was removed in 1.24.0)

[notuntoward]

@the-holsti , that's good to know. Thanks. But hopefully, boruta_py will catch up soon, so that it remains viable into the future.

I was able to solve this by patching boruta_py.py and changing np.int -> int, np.float -> float, and np.bool -> bool, with the current version of NumPy

[notuntoward]

@cluttered-cabinet thanks for that info. It might make sense to put up a pull request with your changes, but checking the existing PRs, it looks like this package isn't maintained.

One of the PRs mentions ARFS as an alternative. I'm going to give it a try.

[cluttered-cabinet]

@notuntoward I'm debating on doing the same...seems like ARFS does have good docs and it's up to date :)

It is already patched here. It is not patched on pypi. So replace boruta_py.py with the file on github should solve the issue.

[luizhdramos]

Just replace np.int, np.float and np.bool for int, floar and bool on Boruta boruta_py.py

[aroyphillips]

Will this be patched on pypi?

[albarsil]

Waiting this change on pypi 🙏
