TypeError: acf() got an unexpected keyword argument 'unbiased'

[YWU99u]

I faced this issue when I tried to use extract_features function from this package.This seemed to be an old, but I still could not figure out the solution for this problem. I've tried to downgrade my statsmodel to 0.12.1, but it turns out it gave me another error saying my pandas package had a compatibility issue as "ImportError: cannot import name 'Int64Index' from 'pandas'".
Does anyone have a solution on how to use this package?

Hi @YWU99u - which version of tsfresh, python and statsmodel are you using? Unfortunately, I can not reproduce this issue.

[XudongWang97]

I got the similar error, and I found the message showed file feature_extraction/feature_calculators.py different from current main branch.

Package versions:
python 3.7
tsfresh 0.20.1
statsmodels 0.13.2

Hi @XudongWang97!
Thanks for sharing those details. The respective file was changes approximately 2 years ago to not contain the "unbiased" parameter anymore, so I am confused why this shows up in version 0.20.1 (3 months ago) again. Are you sure you are using this version and not maybe an older one (just want to double check). How did you install tsfresh? Via pip or conda?

[XudongWang97]

Thank you @nils-braun
I install tsfresh by pip. Now I create a new py3.9 environment and it works. It's strange that I cannot reproduce the error in the old py3.7 one. Some dependency issue?

[nils-braun]

Thanks for looking into this. If you have some time, could you check the package versions in both environments (e.g. with pip freeze) and see if there are significant differences? Thank you!

Hi,

I'm experiencing the same troubles in two different operative systems (Mac OS X and Windows).

I have python 3.9.19 installed but anything works.

I tried to change the python version but still no solution.
Can you help me?

The strange things is that the same script works in an old computer with the following configuration:
tsfresh: 0.20.2
pandas: 2.0.1
matplotlib: 3.7.1
statamodels: 0.14.1
python: 3.9.16

[nils-braun]

Hi @kiraminnie - can you check the version of tsfresh you are using? It looks like this is a (rather) old version.

[kiraminnie]

Hi @nils-braun , thank you for your support. I have installed the 0.18.0 version. Do you think this is the problem? I don't understand the right combination of versions for Python, tsfresh, statsmodels. It seems there is a combination of libraries working...

Thank you again for your support.

[nils-braun]

Yes, tsfresh 0.18.0 is from 2021 (!), so it definitely will not work with any recent packages. I would recommend updating to the newest version (0.20.2). In general, the newest version of a package is usually the best one. If all package authors have their dependencies declared correctly, you do not need to sort out a combination yourself and pip will do it for you.

[kiraminnie]

Thank @nils-braun, I think the problem is that I'm unable to upgrade tsfresh.

I installed many times, all the times using a new environment but the version is always the same: 0.18.0
