Problem with mulidict version when installing Rasa X in windows 10 local environment

[Deprecated] Rasa X Community Edition
1

Hi Guys,

I’ve seen a few threads on Rasa X installation issues and I have tried to follow the instructions here to install Rasa X locally in my windows 10 pc. I have encountered an issue where Sanic 20.12.3 requires a version of multidict (multidict<6.0,>=5.0) that is not compatible with the version required by rasa 2.6.2 (multidict<5.0,>=4.6).

Steps followed:

  1. conda create -n “RasaX” python=3.8
  2. conda activate RasaX
  3. pip install pip==20.2 –user
  4. pip3 install rasa==2.6.2
  5. pip3 install rasa-sdk==2.6.0
  6. pip install rasa-x==0.40.0 --extra-index-url https://pypi.rasa.com/simple

ERROR: sanic 20.12.3 requires multidict<6.0,>=5.0, but you’ll have multidict 4.7.6 which is incompatible.

  1. pip install multidict==5.0 --use-feature=2020-resolver

ERROR: rasa 2.6.2 requires multidict<5.0,>=4.6, but you’ll have multidict 5.0.0 which is incompatible.

I would really appreciate some help with the steps I should follow to install Rasa X or resolve the issue?

@alINGeNT Heya! Nice new error :slight_smile:

Ok, Step by Step install all dependencies and show me error again try to install >= one with == only.

@alINGeNT Can I suggest one thing, if you agree. At the time you install Rasa 2.6.2 , Rasa SDK 2.6.0 have you ignore some red messages dependencies?

@nik202 I like a challenge :slight_smile:

I’ve followed your advice and after reading the multidcit and sanic release notes I have been able to successfully install RasaX on my windows PC with the following steps:

  1. conda create -n “RasaX” python=3.8
  2. conda activate RasaX
  3. pip install pip==20.2 –user
  4. pip install multidict==4.7.6 --use-feature=2020-resolver
  5. pip install pyjwt==2.0.0 --use-feature=2020-resolver
  6. pip install sanic==20.9.0 --use-feature=2020-resolver
  7. pip3 install rasa==2.6.2
  8. pip3 install rasa-sdk==2.6.0
  9. pip install rasa-x==0.40.0 --extra-index-url Simple Index
  10. rasa x

Rasa X starts successfully :grinning:

In the Powershell console I get an asncio error below - not sure if this relates to the community telemetry issue or is something else?

@alINGeNT Hi. Glad its works. For this query you need to set the environment variables to http_proxy and https_proxy.

OR

From command prompt:

SET http_proxy=http://localhost:5002

SET https_proxy=http://localhost:5002

@nik202 Thanks - Rasa x is running without any errors now.

@alINGeNT You are welcome! Congratulations :slight_smile: please can you close this topic with the solution for future reference for others. Thanks.

SOLUTION: To install Rasa X locally on Windows 10 resolving the multidict and asyncio error messages is achieved through the following steps in a powershell or conda console:

  1. conda create -n “Your_Environment_Name” python=3.8
  2. conda activate Your_Environment_Name
  3. pip install pip==20.2 --user
  4. pip install multidict==4.7.6 --use-feature=2020-resolver
  5. pip install pyjwt==2.0.0 --use-feature=2020-resolver
  6. pip install sanic==20.9.0 --use-feature=2020-resolver
  7. pip3 install rasa==2.6.2
  8. pip3 install rasa-sdk==2.6.0
  9. pip install rasa-x==0.40.0 --extra-index-url https://pypi.rasa.com/simple
  10. SET http_proxy=http://localhost:5002
  11. SET https_proxy=http://localhost:5002
  12. rasa x

Thanks to @nik202 for this solution.
