Can't init a new rasa project

Rasa Open Source
1

Hello i’m new in this forum and i’m searching to create an assistant. The problem is i can’t init a new projet with the following command :

rasa init --no-prompt

I’ve got this error :

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/rasa/__init__.py", line 8 in <module>
    from rasa.run import run
  File "/usr/local/lib/python3.5/dist-packages/rasa/run.py", line 7, in <module>

    from typing import Text, Optional, Union, Dict, Deque, Any
ImportError: cannot import name 'Deque'

I followed the installation guide from RASA docs :

apt update
apt install python3-dev python3-pip
pip3 install rasa

I’m running rasa on Debian 9.11 (stretch).

It is better that use Ubuntu or not ? there is missing python package ?

Thanks for help.

What Rasa version are you using? We removed the python3.5 support in Rasa 1.4.0. But not sure if that is related.

I can’t know the Rasa version. When i use the command “rasa”, the error mentionned above on top appear.

Are you using a virtualenv? If not, I would recommend to do so (Installation).

Hello Tanja, I kinda had the same issue.

I was following the manual installing tutorial

I did the following steps:

python3 -m venv --system-site-packages ./venv
source ./venv/bin/activate

pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple

However when I tried to run rasa init --no-prompt , it reports the following error:

Traceback (most recent call last):
  File "/Users/xxxxx/Rasa/rasa-nlu-demo/venv/bin/rasa", line 6, in <module>
    from rasa.__main__ import main
ModuleNotFoundError: No module named 'rasa'

@coorfang Did you got any error? Are you sure, you activated the virtualenv?

@alien what rasa version are you using?

I am also having the same problem. Please tell me how should I remove this problem

@maadhav_sharma You should use venv to skip this problem :

python3 -m venv --system-site-packages ./venv
source ./venv/bin/activate

And after, you can install rasa :

pip install -U pip
pip install rasa

I solved it by using Python 3.6.4

@pavanpolneni22 This seems to be an issue with Tensorflow. Please check out this thread, hope that helps: RuntimeError: dictionary changed size during iteration · Issue #33183 · tensorflow/tensorflow · GitHub
