scipy.linalg.pinv2 not available in scipy 1.9

Hey Sebastian,
I am running some docker containers with always the latest gstools version in it. Now, the import of gstools fails.
Here is the relevant part of the traceback:

File "/usr/local/lib/python3.10/site-packages/skgstat/interfaces/gstools.py", line 151, in skgstat_to_krige
    import gstools as gs
File "/usr/local/lib/python3.10/site-packages/gstools/__init__.py", line 129, in <module>
    from gstools import (
File "/usr/local/lib/python3.10/site-packages/gstools/field/__init__.py", line 33, in <module>
    from gstools.field.cond_srf import CondSRF
File "/usr/local/lib/python3.10/site-packages/gstools/field/cond_srf.py", line 17, in <module>
    from gstools.krige import Krige
File "/usr/local/lib/python3.10/site-packages/gstools/krige/__init__.py", line 20, in <module>
    from gstools.krige.base import Krige
File "/usr/local/lib/python3.10/site-packages/gstools/krige/base.py", line 38, in <module>
    P_INV = {"pinv": spl.pinv, "pinv2": spl.pinv2, "pinvh": spl.pinvh}

I could verify, that scipy==1.9.0 in fact has no scipy.linalg.pinv2 method, while scipy==1.8.0 imports it just fine. The whole practice was run in a Python 3.10 environment.
I solved the issue by installing scipy==1.8.0 first and then gstools. I am also not sure if the pinv2 got moved or removed and if therefore any action on gstools-side is necessary.

scipy/scipy#15737 - Seems like pinv2 should be deprecated and/or removed without a deprecation warning?

Hi Mirko,
thanks for reporting this! It should be resolved with PR #247 .
