pandas environment issue with version 3.x

[Qguill]

Hello,

I have an issue in the part2_01_pstfrom_pest_setup notebook when adding pilot points parameters.

notebooks/tutorials/part2_01_pstfrom_pest_setup/freyberg_pstfrom_pest_setup.ipynb

[28] df_pp = pf.add_parameters(f,
zone_array=ib,
par_type="pilotpoints",
geostruct=pp_gs,
par_name_base=f.split('.')[1].replace("","")+"pp",
pargp=f.split('.')[1].replace("","")+"pp",
lower_bound=0.2,upper_bound=5.0,
ult_ubound=100, ult_lbound=0.01,
pp_space=5) # PstFrom will generate a uniform grid of pilot points in every 4th row and column

The issue seems to be caused by incompatibilities between environment version >3.x and pyemu pp.ultils.py

To resolved this issue, I have created a new environment using environment.yml, adding :

• pandas>=2.0,<3.0

Please let me know if this is a relevant fix,

Regards,
Quentin
