Thank you for the very nice article! The Jupyter notebook was especially useful. While following along, I did notice a few typos though in the installation section. It should be python -m instead of python m, and it should be rasa_core==0.9.6 (without spaces). The link to the Jupyter notebook is also broken, but I found it on the github page you provided. I also had to install sklearn_crfsuite and pygraphviz in order to run some lines in the notebook. I noticed that the chatbot did not like one-word answers, but I was able to get it to work by adding more data to the nlu.md file.
