Import dtale issue in Colab

[Nathan-Dawson]

The following code was run, and the output is provided:

It appears that the issue is related to the import of a private function '_centered' from scipy.signal.signaltools which was likely changed between versions of scipy.

This error persists whether the colab runtime is restarted.

@Nathan-Dawson this is actually a known issue the fix is described here

Looks like you can solve it by upgrading statsmodels. Let me know if you hit any other issues.

Side note: if you haven't already please toss your ⭐ on the repo. Thanks 🙏
