We Are Going To Discuss About Cannot import name ‘_centered’ from ‘scipy.signal.signaltools’. So lets Start this Python Article.
Cannot import name ‘_centered’ from ‘scipy.signal.signaltools’
- How to solve Cannot import name '_centered' from 'scipy.signal.signaltools'
I encountered the same problem while using
statsmodels~=0.12.x
. Increasing the statsmodels package to version0.13.2
, this import issue is resolved.
UPDATE with more notes:
before: installation of fixed version ofstatsmodels==0.12.2
which is dependent onscipy
there was newly releasedscipy==1.8.0
– 2022-02-05 when installing it, got this problem:from statsmodels.tsa.seasonal import seasonal_decompose File "/usr/local/lib/python3.8/site-packages/statsmodels/tsa/seasonal.py", line 12, in <module> from statsmodels.tsa.filters.filtertools import convolution_filter File "/usr/local/lib/python3.8/site-packages/statsmodels/tsa/filters/filtertools.py", line 18, in <module> from scipy.signal.signaltools import _centered as trim_centered ImportError: cannot import name '_centered' from 'scipy.signal.signaltools' (/usr/local/lib/python3.8/site-packages/scipy/signal/signaltools.py)
after:
when bumping upstatsmodels
to the latest version available0.13.2
release 2022-02-08, it works
If you are not usingstatsmodels
but other package which is dependent onscipy
, have a look if there is newer version available (after the release ofscipy
to v.1.8.0
) - Cannot import name '_centered' from 'scipy.signal.signaltools'

If you need to use that specific version of statsmodels 0.12.x with scipy 1.8.0 I have the following hack.
Basically it just re-publishes the existing (but private) _centered function as a public attribute to the module already imported in RAM.
It is a workaround, and if you can simply upgrade your dependencies to the latest versions. Only use this if you are forced to use those specific versions.
import scipy.signal.signaltools
def _centered(arr, newsize):
# Return the center newsize portion of the array.
newsize = np.asarray(newsize)
currsize = np.array(arr.shape)
startind = (currsize - newsize) // 2
endind = startind + newsize
myslice = [slice(startind[k], endind[k]) for k in range(len(endind))]
return arr[tuple(myslice)]
scipy.signal.signaltools._centered = _centered

With scipy 1.8.0, the deprecated form
from scipy.signal.signaltools import _centered
should become
from scipy.signal._signaltools import _centered
Note the underscore in front of signaltools

As it was mentioned by AndrejHan and ThomasCokelaer, you need to upgrade to statsmodels-0.13.2
with:
$ pip install statsmodels --upgrade
or
$ python3 -m pip install statsmodels --upgrade
Your error should disappear
