acf() got an unexpected keyword argument 'unbiased'

[JackShDr]

The problem: acf() got an unexpected keyword argument 'unbiased' when using the extract features function.

The error log is as follows:
"""

I opened the same issue, but it is a duplicate with #897

I encountered the same issue today

Temporarily reverting to statsmodel 0.12.1 fixes this

pip install statsmodels==0.12.1

According to statsmodels' official document, 'unbiased' of the function acf has been changed to 'adjusted' since version 0.12.
I changed the version of statsmodels to 0.11 and confirmed that it was operating normally in linux

v0.11: https://www.statsmodels.org/v0.11.0/generated/statsmodels.tsa.stattools.acf.html?highlight=acf
v0.13: https://www.statsmodels.org/stable/generated/statsmodels.tsa.stattools.acf.html?highlight=acf

Same issue on M1 using miniforge3 and it worked with statsmodels@0.12.1
