ImportError: cannot import name 'pinv2' from 'scipy.linalg'

[Alan-Wolf-VN]

Describe the bug Cannot import TimeSeriesKMeans from tslearn.clustering. The reason can be that scipy.linalg.pinv2 was deprecated with version 1.7 and removed with version 1.9. The functionality has been subsumed by scipy.linalg.pinv:

To Reproduce from tslearn.clustering import TimeSeriesKMeans

Expected behavior import tslearn.clustering without any error message

Environment (please complete the following information):

• OS: Windows 10
• tslearn version 0.5.3.2

I was able to recreate the issue from my end using the following code:

!pip install scikit-learn==0.24
!pip install scipy==1.9
!pip install tslearn
from tslearn.clustering import TimeSeriesKMeans

This issue was fixed in scikit-learn 1.0.X

!pip install scikit-learn==1.0
!pip install scipy==1.9
!pip install tslearn
from tslearn.clustering import TimeSeriesKMeans

Is not throwing any errors for me. Please use scikit-learn>=1.0 to solve the issue.
