My rasa version is 1.1.4
Python version 3.5.7

I encounter a problem with the cashe_key part, all I did was installing innitas and updated the config file.
after writing congif file as :

pipeline: 
  - name: "tokenizer_whitespace"
  - name: "ner_crf"
  - name: "ner_synonyms"
  - name: "innatis.classifiers.BertIntentClassifier"
    pretrained_model_dir: '/bert'
    epochs: 10
    batch_size: 64

@gcgloven I'm sorry, we haven't tested innatis with the Rasa > 0.14

@gcgloven After installing proper version of RASA and executing the training process is not taking place, although there is no error console is idle and not moving forward. Is it is because my system doesn't have the computing power. My system RAM is 12 GB
