numpy 1.24.2 and pmdarima 2.0.3 incompatibility

Describe the bug

Hello,
I have numpy 1.24.2 and pmdarima 2.0.3 installed in my Ubuntu 20.04 LTS machine and, when I run some code that imports pmdarima, I have the following error:

>>> import pmdarima
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/guiaraujo/.local/lib/python3.8/site-packages/pmdarima/__init__.py", line 52, in <module>

    raise AttributeError(__former_attrs__[attr])
AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
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

(notice that the error occurred in interactive shell, indicating that it does not depend on my code)

To Reproduce

Open a shell/bash terminal
Execute python3
Execute:
>>> import pmdarima

Versions

pip install numpy and pip install pmdarima in the latest versions (numpy 1.24.2 and pmdarima 2.0.3)

Expected Behavior

The import should work without any log messages and without any error.

Actual Behavior

The pmdarima import is raising an AttributeError after importing some numpy modules.

Additional Context

No response

What version of scikit-learn do you have installed? This only appears to be an issue on their 0.23.X and older releases. 0.24.X and newer have this issue resolved. FWIW, scikit-learn 0.24.0 was released in 2020.

Thanks for the quick answer. It have upgraded scikit-learn to version 1.2.2 and now it works fine.
