Latest version freezes when trying to run actions server

[samscudder]

Rasa version: 1.5.3

Rasa SDK version (if used & relevant): 1.5.2

Python version: 3.6.9 (Anaconda)

Operating system (windows, osx, ...): RHEL 7 (CentOs) - Running on a Dell XPS i7 with 16Gb RAM

Issue: When I issue "rasa run actions", I get a list of functions, but no line stating that the action server is runner on port 5055. If I try and access the action endpoint, it timeouts. The last version I tested where it ran correctly was 1.4.6 (Python 3.6.9)

Error (including full traceback):
No error message... The computer just freezes. Ctrl-C interrupts the script.

This is the last message that appears until Ctrl-C is entered. When I press Ctrl-C, I just get a ^C and prompt. No traceback.

[sara-tagger]

Thanks for raising this issue, @wochinge will get back to you about it soon✨

Please also check out the docs and the forum in case your issue was raised there too 🤗

[wochinge]

Hi @samscudder ,

unfortunately I cannot reproduce the error.
Can you maybe share your action file (or a minimal example which produces the error)?

[samscudder]

No matter what is in the actions.py, I don't get the

 INFO     rasa_sdk.endpoint  - Action endpoint is up and running on http ('0.0.0.0', 5055)

message. I took my actions file and started removing stuff to see if it would start. I ended up with just the "Hello World" example. Here's a file that fails:

from datetime import datetime, timedelta
from typing import Any, Text, Dict, List, Union

from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher
from rasa_sdk.forms import FormAction

class ActionHelloWorld(Action):

    def name(self) -> Text:
        return "action_hello_world"

    def run(self, dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:

        dispatcher.utter_message("Hello World!")

        return []

This is a newly installed CentOS 7 machine. SELinux is permissive. Here's the (pertinent) installation commands I ran (from history):

    6  sudo yum install curl
    7  cd ~/Downloads/
    8  curl -O https://repo.anaconda.com/archive/Anaconda3-2019.10-Linux-x86_64.sh
    9  sha256sum Anaconda3-2019.10-Linux-x86_64.sh
   10  bash Anaconda3-2019.10-Linux-x86_64.sh
   11  conda update conda
   12  source ~/.bashrc
   13  conda update conda
   14  sudo yum install gcc
   15  sudo mkdir /opt/Chat
   16  cd /opt/Chat
   17  conda create -n Chat python=3.6.9 anaconda
   18  conda activate Chat
   19  python --version
   20  pip install rasa[spacy]
   21  pip install pandas==0.24
   22  pip install keras
   23  python
   24  python -m spacy download pt_core_news_sm
   25  python -m spacy link pt_core_news_sm pt --force

Then I loaded the spacy file, installed MongoDB, configparser, requests and simplejson. Uploaded my models and scripts from another machine, ran training (rasa train --force) and from the onset, rasa run actions wasn't working.

[erohmensing]

It seems like that log was removed: RasaHQ/rasa-sdk@755ef54

which is why you're not seeing it. If you like, you can create a PR to bring it back. Have you tried to check whether the action server is actually running? if you run it on debug mode do you see it receiving calls to the actions?

[samscudder]

Hey Ella!... Thanks for the update.

I ran the actions server, and it is responding. I used the hello world to test it. In debug mode I can see it receiving calls and responding.

I don't think that message should have been removed. The message saying that the server has started is a lot more important than saying that it is going to start (which was left in). Removing a message like that could break a whole load of user watchdog processes that check to see if it is up and running, and I don't remember seeing this in the release notes.

Sorry I'm a bit of a noob here and have no idea what's the right way to create a PR.

Thanks again!

[YunLovesCode]

Hi @samscudder,
I have encountered the same problem as you. I tried many ways but failed. I'm wondering if you found a solution?
Thanks!

[samscudder]

It was just a log message that was removed in Rasa 1.5. The action server was runnning and responding correctly.

Okay, thanks!
