Module for policy could not be loaded

Installed rasa on Ubuntu 18.04 in an anaconda env. Worked until the step rasa train. It then comes up with the above error message Modul for policy … can not be loaded. It seems to pick up the name of the policy from the config.yml. Hence whatever policy is mentioned in there (KerasPolicy or MemoizationPolicy) - it can not load it. Where does it find the policy to load?

Thx, Uli

can show your config.yml file?


Configuration for Rasa NLU.


language: en pipeline: supervised_embeddings

Configuration for Rasa Core.



  • name: MemoizationPolicy
  • name: KerasPolicy
  • name: MappingPolicy

seems that everything is alright

Ok - had to reinstall raza again. As it looks the root issue was a problem with tensorflow which is with version 2.0 incompatible on a hyper-v installation (due to the missing avx on this machine). Re-installed with version 1.14 and rasa train works.
