Assistance with libraries

Hello dear experts,

I am learning the Data Camp course about Rasa and trying to run:

# Import necessary modules
from rasa_nlu.config import RasaNLUConfig
from rasa_nlu.model import Trainer

pipeline = [
    "nlp_spacy",
    "tokenizer_spacy",
    "ner_crf"
]

# Create a config that uses this pipeline
config = RasaNLUConfig(cmdline_args = {"pipeline":pipeline})

# Create a trainer that uses this config
trainer = Trainer(config)

# Create an interpreter by training the model
interpreter = trainer.train(training_data)

# Parse some messages
print(interpreter.parse("show me Chinese food in the centre of town"))
print(interpreter.parse("I want an Indian restaurant in the west"))
print(interpreter.parse("are there any good pizza places in the center?"))

But I get an error:

—> 18 trainer = Trainer(cfg) AttributeError: ‘str’ object has no attribute ‘get’

I am running this on my Jupyter notebook.

  1. Please advise how can I check what is wrong and how to fix it.
  2. How to check which Rasa I am using?

Any assistance with step by step explanation will be highly appreciated.
