Rasa Core version: 0.8.5

Python version: 3.6.4

Operating system (windows, osx, ...): windows 10

Issue:
I have recently updated to RASA NLU v0.12.0 after the update i'm getting this issue

Traceback (most recent call last):

I got this error while using the following method

agent = Agent.load('./models/dialogue/default/dialogue_model', RasaNLUInterpreter('./models/nlu/default/nlu_model'))

We haven't released a new version of rasa core yet that works with NLU 0.12.x - the master version from github should be fine though. We are working on a new release that will be compatible, but it will take a couple days as there are some open PR's that need to be finished up first.

[tmbo]

For the time being, I created an alpha release that should show up on pypi in a couple minutes.

So if you want to use nlu 0.12.x together with core, you can pip install rasa_core==0.9.0a2.

[Harish0596]

@tmbo I see two versions were released with time gap of 30 min which one is stable?

[tmbo]

So the 0.8.6 one is the latest stable one and the 0.9.0a2 is a tagged release from the current development version (which is tested and stable as well, but not yet feature complete and that is why we can not yet release the next major version 0.9.0 for core).

[ctrado18]

I wanted test the new 12.2 but I face same issue. which version of core I have to install now which is working like latest stable but together with 12.2? Shall I use 0.9.0a2 or 0.9.0a3?

[ctrado18]

I ugraded to 0.9.0a2 and get:

[fdevillard]

It should work, but you have to retrain your NLU model using 12.2.x

[akelad]

i'll close for now, let us know if you encounter any more issues

Hi, I referenced to this issue because I had the same one and I don't know how to upgrade to a new version and which.

My error message was :

rasa_nlu.model.UnsupportedModelError: The model version is to old to be loaded by this Rasa NLU instance. Either retrain the model, or run withan older version. Model version: 0.9.0a4 Instance version: 0.12.3

[amir-rafieian]

I have the same problem:

rasa-core = 0.9.7
rasa-nlu = 0.12.3

I just followed the installation instruction on Rasa webpage:

pip install rasa_core
pip install rasa_nlu[spacy]
python -m spacy download en_core_web_lg
python -m spacy link en_core_web_lg en

UPDATE:
I`ve downgraded to version 11.5 and problem solved:

pip install rasa-nlu==0.11.5

[Ghostvv]

@antoinecomp did you try to retrain after you reinstalled rasa?

[samrudh]

working combination to resolve this error:
rasa_nlu = 0.11.5
rasa_core = 0.10.3

[antoinecomp]

@Ghostvv Yes, Probably !

[akelad]

Any reason why not to upgrade to 0.10 and 0.13? 😄
You usually need to retrain models anyways when upgrading to major versions as there can be breaking changes

[serdarbozoglan]

I have the same problem

from rasa_nlu.config import RasaNLUConfig

is not working. I am using the 0.14.3 version of rasa_nlu. What could be the problem

[Ghostvv]

@serdarbozoglan it doesn't exist in rasa_nlu 0.14.3

[bghanchi]

when i run
->from rasa_nlu.converters import load_data
->from rasa_nlu.model import Trainer
they work fine

but when i run -> from rasa_nlu.config import RasaNLUConfig
then i get
cannot import name 'RasaNLUConfig'
why

• Also when i run import rasa_nlu.config then it's work also fine
• version->rasa_nlu =0.11.5 and rasa_core=0.10.3

[Ghostvv]

please try RasaNLUModelConfig instead
