Hi, there When train my own model, I got the Segmentation fault, looks like below. To make the question more clear, I restart a new fresh EC2 on AWS with new install of rasa. The strange thing is that, after install, it’s OK to run “rasa init --no-prompt” to generate the demo file in folder “t-rasa” and get train results successfully. However, when “rasa train --force -vv”, it shows Segmentation fault (core dumped) (venv-rasa) ubuntu@ip-172-31-15-18:~/t-rasa$ rasa train --force -vv 2020-02-12 14:21:23 DEBUG rasa.nlu.training_data.loading - Training data format of 'data/nlu.md' is 'md'. 2020-02-12 14:21:23 DEBUG rasa.nlu.training_data.loading - Training data format of 'data/stories.md' is 'unk'. 2020-02-12 14:21:23 DEBUG pykwalify.compat - Using yaml library: /home/ubuntu/venv-rasa/lib/python3.6/site-packages/ruamel/yaml/__init__.py 2020-02-12 14:21:23 DEBUG rasa.nlu.training_data.loading - Training data format of 'data/nlu.md' is 'md'. 2020-02-12 14:21:23 DEBUG rasa.nlu.training_data.loading - Training data format of 'data/nlu.md' is 'md'.

Thanks, the post is very helpful and in time. For anyone run ubuntu 18.04 on AWS. Here is what works in Feb. 12 sudo apt update sudo apt install python3-dev python3-pip python3-venv python3 -m venv --system-site-packages ./venv-rasa source ./venv-rasa/bin/activate pip3 install -U pip pip3 install rasa pip3 uninstall gym pip3 install gym==0.15.4 pip3 uninstall sanic-plugins-framework pip3 install sanic-plugins-framework==0.8.2

Okay @yiouyou, thank you.

What image did you use for your EC2 instance? (Linux/ubuntu/etc.)

When I try to run rasa docker file from github I get this error:

Can you help?
