`np.int` was a deprecated alias for the builtin `int`.

[a3678911]

My version is R1.10.1. If my numpy's version is beyond or equal to R1.24.0, an error will output like this when skopt.space.Integer is used:
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.
This is how to fix it:

Hope next version will fix it.

same issue.

I have the same error.

return np.round(X_orig).astype(np.int)
Change it to:

return np.round(X_orig).astype(int)
in the file : skopt/space/transformers.py

EDIT : There is a PR #1159 but didn't pass the CI checks 🤔

Another workaround:

np.int = np.int64

has worked for me for now.

There are several open PRs to fix this issue -- do we know if this project is being actively maintained/monitored?

Seems like it is not: https://snyk.io/advisor/python/scikit-optimize

No update in two years

May be worth looking at other packages e.g. optuna

Isn't optuna also relying (at least partly) on skopt?

Hey, I have tried fixing this issue --> #1187
Hopefully, it will be sorted soon :)

Good job! When will be the next Release Version released?

Tried fixing this issue too. Would not pass the tests - due to some version name inconsistency.
