Did you managed to run the code? I followed your step 1 and 2 and get:
SyntaxError: import * only allowed at module level
from tvgl.
I think this could be solved as well (you just have to replace import *
). But if you want to do Time-Varying Graphical Lasso, there are other packages as well which are running in Python 3.x., for example https://github.com/fdtomasi/regain or my own implementation https://github.com/fabian-sp/GGLasso.
from tvgl.
Replace import *
with?
Thank you for the kind response. At first glance (now I am going to look more carefully) it seems that the two links are not directly referring the Time-Varying Graphical Lasso paper code which I was looking for (one of them is the Latent Variable Time-varying Network Graphical Lasso and the other Multiple Graphical Lasso problem), but thank you they could be very useful for me. Are there some similar packages also for Matlab? Is there an updated python 3.x version of the code of the TVGL paper?
from tvgl.
instead of *
list all functions that are used from the module.
So regain
implemented Time-varying Graphical Lasso with and without Latent Varibales, the version without is here https://github.com/fdtomasi/regain/blob/master/regain/covariance/time_graphical_lasso_.py
My package has Group Graphical Lasso and Fused (=Time-Varying) Graphical Lasso. So both packages should be adequate for solving Time-Varying GL problems.
I don't know of a TVGL version for 3.x, also not sure whether there is code for Matlab.

Thank you 💪🏻

@fabian-sp It seems that regain's implementation of Time-varying Graphical Lasso only ever outputs a diagonal matrix for each time point when the sample size for each time point is one. This is a flaw in their implementation.
