Rasa-x 1.0.1 compatibility issue with Rasa 2.8.2 & 2.8.17 models

holyone2two · December 22, 2021, 10:35am

I am using Ubuntu 20 and following the most recent install guidelines for v1.0.0 and the Ephermeral InstallerIntroduction .

and rasa init

I can log into the GUI but when I upload the model from file it says " Upload failed

Something went wrong. Please try again." and the logs for the Rasa X server shows:

It sounds like a compatibility error, but as far as I can see these versions of Rasa Open Source and Rasa-X should be compatible? Compatibility Matrix

Many thanks for any help on this

nik202 · December 22, 2021, 11:01am

@holyone2two try update the rasa and rasa-sdk with upper version please but less then rasa 3.x as rasa x is not supporting the latest version yet ? Hope that will solve the issue.

holyone2two · December 22, 2021, 11:43am

Thank you for this suggestion, but I have read that Rasa and Rasa-SDK 3+ is not currently compatible with Rasa-X at all, so I purposely am not using the latest Rasa version (3.0.0).

This is suggested here and on the forums.

Is the documentation wrong?

nik202 · December 22, 2021, 11:45am

@holyone2two yeps you are right, my bad I am still on rasa 2.X that why said that update to latest, basically I mean with upgrade version and less then 3.x. Let me update above.

@holyone2two yes I am sure it related to rasa and rasa-sdk version my combination is 2.8.1 and 2.8.2 with rasa x 0.42.4

holyone2two · December 23, 2021, 8:56am

I should note that I spotted there are later versions of Rasa such as pip install rasa==2.8.17 - but when I try this upgrade, the pip dependency resolver gets stuck

nik202 · December 23, 2021, 1:10pm

@holyone2two can you share some error screenshot please ?

holyone2two · December 23, 2021, 6:10pm

I managed to update my Rasa Open Source version to latest minor fix subversion 2.8.17:

╰─❯ pip freeze | grep rasa                                                                                                                                                                                                               ─╯
rasa==2.8.17
rasa-sdk==2.8.3

By creating a fresh python 3.8 conda environment, and upgrading pip, before installing it.

Even when I freshly generate (rasa train) the model file with this, I get the same error though.

Any ideas much appreciated, as I am baffled how to use Rasa X 1.0.1

holyone2two · December 23, 2021, 6:15pm

I also tried a model trained with Rasa open source v3 and that had same issue.

nik202 · December 24, 2021, 12:58pm

@holyone2two Right, rasa v3 is not Compatible with Rasa X, and from the above traceback - please see the compatibility issue and fix that I guess that is the main issue and train the model.

@holyone2two confirm me that you are working on local machine is that right?

holyone2two · December 24, 2021, 3:14pm

I am aware that v3 is not compatible and that’s why I used v2, (see the pip freeze in my posts above for specific versions) but given the error is seemingly version related I just made a note that I’ve tried v3 too.

Yes I’m testing on local Ubuntu 20 machine with Conda environment for python

nik202 · December 24, 2021, 4:30pm

@holyone2two what’s your issue then?

holyone2two · December 24, 2021, 4:53pm

When using Rasa Open Source 2.8.17 with Rasa X 1.01 which are compatible according to the compatibility chart, I get the error pasted here

nik202 · December 24, 2021, 5:35pm

@holyone2two you can try downgrade rasa to 2.8.14?

holyone2two · December 25, 2021, 4:52pm

I have tried downgrading to 2.8.14

╰─❯ pip freeze | grep rasa                                                                                                                                                                                                                                                  ─╯
rasa==2.8.14
rasa-sdk==2.8.3

then doing a rasa train operation to get the new model file. But get the same error

After connecting Rasa-X to github version control, and clicking add model > train model, I also get the following error:

holyone2two · December 25, 2021, 5:40pm

I saw you had it working with these versions, so I downgraded my rasa-X to 0.42.4, and my Rasa Open Source to 2.8.2 and started a new Rasa X server, but uploading a freshly trained model gives the same error as before:

AttributeError: 'NoneType' object has no attribute 'version'
'NoneType' object has no attribute 'version

My best guess is that Rasa-X is expecting some configuration that I am not providing.Should my values.yml provide anything beyond simply the version of Rasa-X I wish to run?

holyone2two · January 4, 2022, 8:25am

Does anyone have any advise on this? Spent days trying to run Rasa-X with Rasa Open Source, and given I am following the official documentation to the letter, I find it concerning I cannot get it to run.

soerenetler · January 12, 2022, 9:22am

Hi Benjamin @holyone2two, I have a very similar error. I am installing RASA-X on a VM on digitalocean (ubuntu 20.4). I used the new Rasa Ephemeral Installer (REI) to install RASA-X without any custom configuration. When training models I get the same NoneType object has not attribute version and KeyError: worker. I asked my question here: Rasa X Unauthorized when training model

Did you find any solution? I am stuck for now

holyone2two · January 12, 2022, 9:25am

I am afraid I have no solution yet. This seems like a fundamental bug in the current codebase to me, given it makes Rasa-X unusable and I have followed official docs to install. There has been no support for this issue from Rasa developers on this over the last few weeks it would seem.

polymaxim · January 17, 2022, 12:47pm

I am having the same issue after deploying Rasa X with Helm. I hope that a solution comes really soon.
