IOStream.flush timed out.

[D. K]

Hello, 
I'm trying to run an old working code on a VARMAX model for the same dataset, which a few months ago was working, but now I'm getting an unexplained error. The only modification I made was to calculate a variable again, rather without meaning.

I first get a warning:

anaconda3/lib/python3.11/site-packages/statsmodels/base/optimizer.py:18: Future Warning: Keyword arguments have been passed to the optimizer that have no effect. The list of allowed keyword arguments for method bfgs is: gtol, norm, epsilon. The list of unsupported keyword arguments passed includes start_states. After release 0.14, this will rise.
  warnings.warn(

 

And after four hours, I get:

IOStream.flush timed out.

 

The code had no issues and was able to converge within twenty minutes or so. I've also run a version ignoring the warning; the same issue happened. The code and data are the same, but this time I am not sure what is going wrong. The only difference from last time is that I bought a new computer. I would greatly appreciate it if you could help me.

 

By the way, I read here  https://stackoverflow.com/questions/70580988/iostream-flush-timed-out-what-does-it-mean    that I should do something with the kernel but did not get the right way to process it. I do not recall if I was running StatsModel 0.14 or a previous version last time. If you think the solution is to downgrade,  will do that. 

Thank you for any, help!
