Tensorflow Error on Rasa X 0.35

[Deprecated] Rasa X Community Edition

Hi !

I updated Rasa X from 0.34 to 0.35 using Docker Compose Install Script.

I got the following errors when adding messages to conversations

Hi @guillaumecostanza! Which version of rasa open source have you used for training your model? Maybe you need to retrain the model.

Hope this helps!!

Hi @kalkbrennerei.

Unfortunately re-training didn’t changed anything. Rasa Version is 2.2.5

I removed SpacyNLP + SpacyTokenizer + SpacyFeaturizer from the pipeline for now :

pipeline:
- name: WhitespaceTokenizer
  intent_tokenization_flag: True
  intent_split_symbol: "+"
  token_pattern: None
# - name: SpacyNLP
# - name: SpacyTokenizer
#   intent_tokenization_flag: True
#   intent_split_symbol: "+"
# - name: SpacyFeaturizer
- name: RegexFeaturizer
  case_sensitive: False
  use_lookup_tables: True
  use_regexes: True
- name: LexicalSyntacticFeaturizer
- name: CountVectorsFeaturizer
- name: CountVectorsFeaturizer
  analyzer: "char_wb"
  min_ngram: 1
  max_ngram: 4

- name: CRFEntityExtractor
  BILOU_flag: True

- name: DIETClassifier
  epochs: 300
  entity_recognition: False

- name: EntitySynonymMapper

policies:
- name: TEDPolicy
  epochs: 100

For information, we run the following commands directly into the rasa-production container to add spacy additionnal ressources :

python3 -m spacy download fr_core_news_md
python3 -m spacy link fr_core_news_md fr
5

are you using the same spacy versions during training as in production container?

6

not sure but I think you need to specify the language in your config so that spacy would use non English embeddings

7

Yes it is present in the pipeline !

The training is done in our CI and then uploaded to Rasa X. I’ve attached our pipenv lock file
