Unable to start multprocTCPBase on thespian shell

[jemferraz]

Hi,
I've been trying to create an actor system in my windows 10 laptop, without success: I keep receiving the message thespian.actors.InvalidActorAddress: ActorAddr-(T|:1900) is not a valid ActorSystem admin, although this port is not being used by any program, as given by netstat -ano -p tcp:

C:\Users\josee>netstat -ano -p tcp

I then tried to start the the actor system in the thespian shell, to no avail:

I've already tried to turn off Mcafee firewall, as well as uninstall and re-install thespian, but without success.

Do you have any idea of what might be happening and what can I do?
Thank you for your attention,

[dpeschman]

Howdy. Regarding the shell start, the base has an “i” in multi - multiprocTCPBase.

[jemferraz]

@dpeschman Thank you very much for your observation! That was a very stupid error...

However, I am still unable to create the actor system:

Any idea?

[kquick]

This may be due to some Windows firewall or virus protection. You might check those settings, or try a different port (those above 16384 are commonly used for users).

@kquick Thank you very much for your suggestions!

However, after turning off both the antivirus firewall (McAfee LiveSafe) and the Windows firewall & network protection (Domain, Private and Public networks), I was still unable to start the actor system. I've also tried to use different ports (1901 and 16385), and I've also added an inbound rule for ports 1901 to 1950 in the Windows Defender Firewall to allow Pyhon programs, but none of these actions worked out, and I kept on receiving the same type of error, namely:

ActorAddr-(T|:16385) is not a valid ActorSystem admin

Sorry to bother, but do you have any suggestion? Do you think that there might be a problem in the hardware (I am currently testing using a Dell Inspiron 7580 laptop, with Windows 10 Pro, but previously I have run the model in a different machine, a Dell desktop without any problem...)?

[mistrey]

This bug is a regression that was introduced after version 3.10.5. This version is still working for me with the multiprocTCPBase implementation under Windows. The newest version doesn't.

[jemferraz]

@mistrey Ah, got it... May have to revert back to the previous version then. Thanks for the insight!

[gbanasiak]

#79 fixed this. I was still getting the same symptom on Windows with 4a7b522, but not with acf5cb2.

[jemferraz]

@gbanasiak Thanks for your warning!
I've uninstalled thespian and reinstalled it (with the --no-cache-dir option), but to no avail: I still received the same error, namely

Starting multiprocTCPBase ActorSystem
Capabilities: {}
***ERROR from Actor System: ActorAddr-(T|:1900) is not a valid ActorSystem admin

Perhaps this is still not the correct commit. Do you have any suggestion?

[gbanasiak]

@jemferraz #79 was not released yet. The latest release is 3.10.7 from January 2023.

Can you verify the fix by installing Thespian directly from the source?

pip uninstall thespian
pip install git+https://github.com/thespianpy/Thespian.git

The version was not bumped up yet in the source, so it will still show 3.10.7 but hopefully the behavior will be different.

[jemferraz]

@gbanasiak Sure!
I reinstalled Thespian as you instructed, and now it is working perfectly:

thespian> start multiprocTCPBase
Starting multiprocTCPBase ActorSystem
Capabilities: {}
Started multiprocTCPBase ActorSystem
thespian>

Thank you very much for your help!!!

[gbanasiak]

@jemferraz Note this is just a temporary solution. You should upgrade to 3.10.8 once it is released.

[jemferraz]

@gbanasiak I'll do that as soon as it is released!
Thanks for the advice!!
