Rasa NLU stater pack - rasa_nlu not found error

I’m following the stater pack tutorial and downloaded Rasa_nlu / associated packages and when I try to “make train-nlu”, I’m getting below error.

pip install rasa_nlu gives back statemtns that the requiements are already satisifed.

mk@mk:~/Desktop/rasa/starter-pack-rasa-nlu$ make

    run-nlu

python -m rasa_nlu.train -c nlu_config.yml --data data/nlu_data.md -o models --project current --verbose

Hey @Matheswaran!
Can you tell me which python version you are using and which versions of rasa_nlu, rasa_core and rasa-core-sdk you have installed (you can check this by running pip list | grep rasa and python --version)?
