sc.pp.regress_out() trouble importing _centered from scipy.signal.signaltools

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of scanpy.
• (optional) I have confirmed this bug exists on the master branch of scanpy.

Hello,

This may be a problem outside the realm of scanpy functionality, but I thought it best to bring up in case it is relevant or in case anyone here has seen something before while trying to use scanpy. It looks like I can having trouble importing a dependency of the sc.pp.regress() function. I don't think the data here is relevant, just something in my set up. I tried updating all the libraries so that everything is up to date. This problem just started occurring today (2/10/21) and had no issue yesterday, so I figure it was a change on the scanpy end that I didn't keep up with proprely.

sc.pp.regress_out(merged_adata, ['pct_counts_mt', 'pct_counts_rp'])

yields the following error

/broad/software/free/Linux/redhat_7_x86_64/pkgs/anaconda3_2020.07/lib/python3.8/site-packages/statsmodels/tsa/filters/filtertools.py in <module>

ImportError: cannot import name '_centered' from 'scipy.signal.signaltools' (/home/unix/jjeang/.local/lib/python3.8/site-packages/scipy/signal/signaltools.py)

Versions

Start at sc.pp.regress_out() and reproduce the ImportError using the listed Python package versions, especially scipy and statsmodels. Trace the dependency import that fails and verify a supported dependency combination or compatibility fix prevents the error.
