(vlogs_v2) [root form_bot_v6]# rasa data convert config

Your model configuration contains the ‘FormPolicy’. Note that this command does not migrate the ‘FormPolicy’ and you have to migrate the ‘FormPolicy’ manually. Please see the migration guide for further details: Version Migration Guide 2020-11-26 06:54:18 INFO rasa.shared.utils.validation - The ‘version’ key is missing in the training data file /rasa/bots_v2/form_bot_v6/domain.yml.

Can you post your config.yml file?

The only thing that sticks out to me is that pipeline templates, e.g. supervised_embeddings were all deprecated even before the update to 2.0. Since your config looks pretty standard, I’d suggest starting with the new default config instead of trying to convert your old one. Here is the new default config for convenience:


language: en

pipeline:
# # No configuration for the NLU pipeline was provided. The following default pipeline was used to train your model.
# # If you'd like to customize it, uncomment and adjust the pipeline.
# # See https://rasa.com/docs/rasa/tuning-your-model for more information.
#   - name: WhitespaceTokenizer
#   - name: RegexFeaturizer
#   - name: LexicalSyntacticFeaturizer
#   - name: CountVectorsFeaturizer
#   - name: CountVectorsFeaturizer
#     analyzer: char_wb
#     min_ngram: 1
#     max_ngram: 4
#   - name: DIETClassifier
#     epochs: 100
#   - name: EntitySynonymMapper
#   - name: ResponseSelector
#     epochs: 100
#   - name: FallbackClassifier
#     threshold: 0.3
#     ambiguity_threshold: 0.1

policies:
- name: MemoizationPolicy
- name: TEDPolicy
  max_history: 5
  epochs: 10

Thanks for taking out time and trying to resolve it.

Yeah… I was also thinking of doing it manually… but I don’t think error is because of the pipeline template as the error is coming while migrating the fallback policy.

It looks like the Fallback Policy needs to be manually migrated to a number of different locations:

Which requires the following updates to the config (note it is added to both policies and pipeline):


policies:
  # Other policies
  - name: RulePolicy
    core_fallback_threshold: 0.3
    core_fallback_action_name: "action_default_fallback"

pipeline:
  # Other components
  - name: FallbackClassifier
    threshold: 0.4
    ambiguity_threshold: 0.1

and rules.yml:


rules:
  - rule: Ask the user to rephrase whenever they send a message with low NLU confidence
    steps:
    - intent: nlu_fallback
    - action: utter_please_rephrase

I still don’t believe you’ll be able to convert the file due to the pipeline template, so you’ll want to remove that as well.

I would like to share the following Python script that facilitates the migration process from Dialogflow to Rasa Open Source.

Feel free to test it and share any comment/issue/improvement

Best,
