Failed to load the component rasa

Rasa Open Source
1

I am using rasa as a python library. Here is my directory structure

chat-bot/
  bots/
    models/
       rasa/
         my-model.tar.gz
    rasa_bot.py
  projects/
     rasa/
       actions/
       components/
         data_processing.py
       data/
         nlu.yml
         stories.yml
       config.yml
       domain.yml

Here is how my config.yml

language: en
pipeline:
  - name: components.data_processing.DataProcessingComponent
  - name: WhitespaceTokenizer
  - name: CountVectorsFeaturizer

and this is how I train the model

rasa train --fixed-model-name my-model --out ../../bots/models/rasa/

And in rasa_bot.py This is how I am loading the model

model = RasaBot.__get_model("my-model.tar.gz")
# get the agent from model and action server
ACTION_ENDPOINT = os.getenv('ACTION_ENDPOINT')
agent = Agent.load(
           model,
           action_endpoint=EndpointConfig(ACTION_ENDPOINT)
        )

and __get_model method

@staticmethod
def __get_model(modelName):
    MODEL_LOCATION = os.environ.get('MODEL_LOCATION')
    return '{}/{}'.format(MODEL_LOCATION, modelName)

    MODEL_LOCATION = os.environ.get('MODEL_LOCATION')
    return '{}/{}'.format(MODEL_LOCATION, modelName)

but this is showing this error

@ermarkar To double-check, what command did you run to get this stacktrace? At a quick glance sounds like the path to your component needs to be fixed because components can’t be found; maybe you’re also missing an __init__.py in components?

In my rasa_bot.py , I added

RASA_DIR = os.getcwd() + "//projects//rasa"
sys.path.append(RASA_DIR)

@anca thanks for the answer, I tried adding the __init__.py in components folder, even with the parent folder too, but it did not work, somehow i figured out the solution and answered.

Thanks
