@Borda install scipy==1.11.4 according to this issue: reiinakano/scikit-plot#119

[SkafteNicki]

Alternative set dython>=0.7.5 as according to this issue: shakedzy/dython#156

[Borda]

@Borda install scipy==1.11.4 according to this issue: reiinakano/scikit-plot#119

wanted to avoid this freeze in tests...

Alternative set dython>=0.7.5 as according to this issue: shakedzy/dython#156

I did freeze to latest 0.7.7 and bump matplotlib >=3.6.0 which is still 2022
