Rasa X not loading models suddenly

[Deprecated] Rasa X Community Edition
1

Hi all,

Anyone that can help me resolve this issue as this goes over my head?

When trying to run Rasa X locally it won’t load any models, while it used to work previously. It does open Rasa X on the browser, but no models or previous conversations are loaded.

Error when running rasa x, running rasa shell works perfectly fine.

These are the versions of Rasa tools I am currently using:

Rasa Version      :         2.6.2
Minimum Compatible Version: 2.6.0
Rasa SDK Version  :         2.6.0
Rasa X Version    :         0.40.0
Python Version    :         3.8.0
Operating System  :         Windows-10-10.0.19041-SP0

I have tried the solution presented in “Rasa X failed to run”, although to no avail.

Below are the errors that occur when running rasa x.

Many thanks!

@Hadzy can you try clean your cache and browser cookies and let me know please.

3

Hi Nik, Thanks for the response. Unfortunately, clearing browser cache and cookies did not help. I get the same error as previously.

I do have the previous conversations loaded now though, but not the models.

4

@Hadzy is that your rasa x is opening in the browser window?

5

@nik202, yes rasa x opens up in the browser, but doesn’t show the models.

6

@Hadzy did you trained your model before using rasa train --debug if not before running rasa x please run this command and share me the screenshot what you get?

7

@nik202 I will do that and respond. However, in the mean time I tried updating rasa, but now when I run RASA X I get the same issue as in RASA X running Error: Make sure to start Rasa X with valid data and valid domain and config files - #22 by nik202. I believe the reason is because it is incompatible with my rasa.db files. Any way to keep the files or the data from it without removing the files?

8

@Hadzy can you downgrade to rasa x 0.39.3? and follow this solution thread please Installing rasa - #7 by nik202

9

@nik202 I am making a new environment within conda and following your installation steps. During installation of Rasa X I got the message INFO: This is taking longer than usual. To prevent this I want to downgrade the pip version, however when running pip install pip==20.2 I get the following message:

image1529×401 24.4 KB

10

@Hadzy install without that please, if you getting longer time then only and mention --user at the end of command.

11

@nik202 I did the installation, but still the same message when running rasa x. Also with a clean rasa init model it gives the same message:

$ rasa x
