pstfrom_mf6.ipynb doesn't run to completion and returns an error

[gball-usgs]

The example notebook pstfrom_mf6.ipynb fails to run completely due to an error originating from os_utils.py. When trying to run the notebook it fails when trying to run the model with noptmax = 0.
A non-zero value is returned at line 125 : ret_val = os.system(cmd_str)
I tried two different environments: a fresh install of everything required and the environment I've been using with flopy and pyemu for the past year.

Exception Traceback (most recent call last)
Cell In[48], [line 157]
[154] pst.write(os.path.join(pf.new_d, "freyberg.pst"))
[156] # run with noptmax = 0
--> [157] pyemu.os_utils.run("{0} freyberg.pst".format(
[158] os.path.join("pestpp-ies")), cwd=pf.new_d)
[160] # make sure it ran
[161] res_file = os.path.join(pf.new_d, "freyberg.base.rei")

do you have pestpp-ies and mf6 in your path or in the template dir that gets created? I dont think that notebook goes to any great lengths to help you get the correct bins in the correct locations...if you wanna better experience playing with pstfrom, you might want to checkout the gmdsi notebooks. there's machinery in those notebooks to get the binaries setup for you...

@gball-usgs, did you get this issue sorted?
