with pandas Version: 2.0.1, when using dill to load data, above code runs into moduleNotFound error

Can you give a minimal self-contained example of code that throws this error?
Also, what version of dill and what version of python and what OS did you test with?

[Mike McKerns]

I'm not experiencing an issue with a simple test:

Python 3.8.17 (default, Jun 11 2023, 01:54:00) 
[Clang 13.1.6 (clang-1316.0.21.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> import dill
>>> d = pd.DataFrame(dict(a=pd.Series(dict(q=2,w=3)), b=pd.Series(dict(q=4,t=5))))
>>> s = dill.loads(dill.dumps(d))
>>> s
     a    b
q  2.0  4.0
t  NaN  5.0
w  3.0  NaN
>>> 
>>> dill.__version__
'0.3.8.dev0'
>>> pd.__version__
'1.5.3'

Of course, you can see my pandas version is 1.5.3...
Can you give an example like this that triggers the error?

[Mike McKerns]

Also, was the same version of dill and/or pandas and/or python used to save and to load the data?

i believe this is the issue

the error happened when opening a file saved in colab. found out colab and my laptop have different versions of pandas
