Issue arising with current version of scipy

[sirmurphalot]

I think that the current version of scipy is causing issues with loading sepia . From my module loading:

import scipy
import scipy.signal.signaltools
import seaborn as sns
import matplotlib.pyplot as matplt
import numpy as np
import pandas as pd
import math
import random
from sepia import *

Gives the following error:

runcell(0, '/Users/murph/Documents/GP_playtime/GP_sepia.py')
Traceback (most recent call last):

  File "/Users/murph/Documents/GP_playtime/GP_sepia.py", line 31, in <module>
    from sepia import *

    from .filters import api as filters

  File "/opt/anaconda3/lib/python3.8/site-packages/statsmodels/tsa/filters/api.py", line 6, in <module>
    from .filtertools import miso_lfilter, convolution_filter, recursive_filter

  File "/opt/anaconda3/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' (/opt/anaconda3/lib/python3.8/site-packages/scipy/signal/signaltools.py)

Per the suggestion here, I worked around this by placing:

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

before my sepia call. This is all with Python 3.8.8 and Scipy 1.10.1.

Hi, I'm not able to replicate the error with the following conda environment on linux. Looks like you're on windows. Don't have access to a windows machine, but tests passed on windows with python 3.8. Can you try again with this environment?

name: issue-51
channels:
  - defaults
dependencies:
  - python=3.8.8
  - tqdm
  - numpy
  - pandas
  - scipy=1.10.1
  - seaborn
  - notebook
  - statsmodels

Upon further investigation, I think this was an issue with my conda environment having loaded statsmodels.api, which caused the issue with that version of scipy -- not sepia's value at all. Thanks for your attention!
