Seems like postgress error to me. How to solve this problem.

Hi @feroze.chaudhry, we have since released two patch versions. It would be great if you could try this again using 0.19.2. You can update the version in your .env in the project directory (/etc/rasa).

feroze.chaudhry · June 19, 2019, 7:32am

I have updated the rasa x version but the issue is not resolved. The issue is in postgress image i suppose. Following are the logs after update.

I am still waiting for the reply. Can you please look into it.

FelixKing · June 20, 2019, 12:17am

Have you got this working at all? I had trouble early on with docker and installed via pip instead, be sure to follow these steps,

curl -sSL -o install.sh https://storage.googleapis.com/rasa-x-releases/stable/install.sh

sudo bash ./install.sh

cd /etc/rasa

sudo docker-compose up -d

cd /etc/rasa

sudo python rasa_x_commands.py create --update admin me PASSWORD

create a password and swap with PASSWORD

Head over to domain or your IP and check it out. I was using Digital Ocean for this, just did it about an hour ago and had no problems. I installed with ‘stable’ instead of picking a version too, and it worked.

Fresh install on Ubuntu? update/upgrades?

feroze.chaudhry · June 20, 2019, 12:16pm

I have freshly installed the it now the error seems to be gone but i cant be able to access rasa gui on browser. following are the logs

rasa-production_1  | 2019-06-20 12:14:37 DEBUG    rasa.core.agent  - Model server didn't find a model for our request. Probably no one did train a model for the project and tag combination yet.

Can you please tell me what is the problem why i cant be able to access gui

feroze.chaudhry · June 20, 2019, 12:19pm

Its even not accessible from host machine getting connection refused.

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET http://localhost:5002/login?username=me&password=12345678
[1] 13341
root@my-machine:/etc/rasa# curl: (7) Failed to connect to localhost port 5002: Connection refused

feroze.chaudhry · June 20, 2019, 1:08pm

I resolved the issue. Sorry i was trying to access the gui like we access gui when rasa-x is installed through pip http://localhost:5002/login. Actually we have to access the gui through nginx. The issue is resolved now

aherrera · June 25, 2019, 12:58pm

I have the same problem, “Model server didn’t find a model for our request. Probably no one did train a model for the project and tag combination yet.” Can someone help in how to link rasa-x with an exisiting rasa proyect or even the rasa-x-demo one? thanks

rutsam · October 15, 2020, 4:00pm

How do you then access rasa-x through nginx?

ermarkar · April 7, 2021, 1:36pm

will this solve the db translation error meesage?
