Rasa Core version: 0.8.0a4 | 0.8.0a4-py2.7.egg

Python version: 2.7.14 :: Anaconda custom (64-bit)

Operating system (windows, osx, ...): ubuntu 16.04

Issue: train-core
running command: sudo python -m rasa_core.train -s data/stories.md -d domain.yml -o models/dialogue --epochs 300
When I train-core using "sudo" it gives following error:-
Traceback (most recent call last):

And when I train-core without using "sudo" it gives following error:-

same here... I'm also facing the ImportError issue for typing package and Deque model.

tried to uninstall the following package and installed it with updated version still stuck at the same error. @tmbo

same here - pip list | grep typing gave me typing (3.5.3.0).

But unlike @venky14 uninstalling and installing the latest version didn't persist the problem.

pip uninstall typing && pip install typing lead to version 3.6.2 being installed.

To be added:

had the issue with rasa_core.run without using sudo
os: Ubuntu 14.04.5

Is it possible that is has something to do with permissions? - using sudo in combination with pip and mixing system python with the user one.
Facing this issue on a older server instance where things are a bit messed up. Locally I do have errors at all.

I am not sure where this is coming from. When running pip install rasa_core or pip install -e . in the source root and a clean environment I get typing==3.6.2. I mean there is a version bound on it in setup.py as well as a specific version set in requirements.txt.

I will make the change to use Pipfiles instead of requirements.txt soon anyway - might fix this setup issue as well.

This issue surfaced with the latest version of RASA (0.8.0a4). It, or one of its dependencies, relies on a Deque collection type in the typing module, which doesn't exist by default in Python 2.7 like it does in later versions--I want to say 3.5 and up. You can upgrade your Python, or you can install the wheel for your Python version. To install, download the correct wheel, and then in the directory, run pip install <filename>.

I am having the same issue with python 3.5.2, reproducible for moodbot:
