@sharifm How you installed rasa and rasa-sdk whilst using conda or pip?

================================================================================== Below installation went well

conda create --prefix D:\bot_poc1 python=3.8.8 conda install ujson conda install tensorflow pip install rasa

================================================================================== However while installing rasa-x , it was taking too much time with 1st command w/ multiple version(s) installation for same library, So aborted the process below command

pip install rasa-x -i https://pypi.rasa.com/simple

================================================================================== So did CNTRL+C and re-run the installation w/ below {modified} command

================================================================================== pip install rasa-x -i https://pypi.rasa.com/simple --use-deprecated=legacy-resolver

Do you think, i should have older version of above library (like attrs<20.0,>=19.3 / kafka-python<2.0,>=1.4 / questionary<1.6.0,>=1.5.1 / sanic-jwt<2.0.0,>=1.6.0 / ujson<2.0,>=1.35)

@sharifm You want to install Rasa-X local right? Yes or No?

@sharifm From where you have seen this command: pip install rasa-x -i https://pypi.rasa.com/simple --use-deprecated=legacy-resolver , why there is -i what is the significance of this?

Yes, I trying it locally.

@sharifm

Please create the new fresh environment and follow these steps, if you have already installed Anaconda you can leave the Anaconda installation process.

Need to install Anaconda First https://youtu.be/GlR60CvTh8A only follow the anaconda installation process, nothing more. Switch to below process.

create a project folder rasa

    1. conda create -name “Your_Environment_Name” python=3.8 or python==3.7.7
    2. conda activate Your_Environment_Name
    3. pip install pip==20.2 --user
    4. pip install rasa-sdk==2.8.1
    5. pip install rasa==2.8.0
    6. pip install rasa-x --extra-index-url https://pypi.rasa.com/simple
    7. rasa init     follow the instructions
    8. running rasa type rasa shell 
    9. for training the bot rasa train
    10. In new separate terminal for custom action i.e action.py run rasa run actions

Whilst, installing you will see some package and dependencies error, please install that, but only >= one.

Most Common Errors: Can arise some sets of dependencies errors, please just install as it mentioned but just install >= one only.

  • much common error is multidic please follow this pip install sanic==20.9.0 and then install pip install multidict==4.7.6

Note: You can able to install and see the rasa installation whilst using rasa --version

Please share, the upcoming errors whilst following this process. Good Luck!

Note: This process is able to install Rasa-X but if you encountered other issues, please check the other threads also for different installation, in conversation.

I don’t know , i just looked at help in RASA community forum and decided to run same command.

Here is the link < RASA X unable to install via anaconda - #5 by ChrisRahme >

-i is shorthand for --extra-index-url

I did that in separate env (d:/bot_poc) and installed <python=3.8.8> , tensorflow<2.3.0>.
I just uninstalled RASA-X. Anyway-I will create new env again and follow your above steps.

@sharifm Here I uploaded the Lib and Scripts folders of a Rasa virtual environment, you can download them and extract them in the root of your virtual environment folder (rasa_test_1) if the following versions match yours (or if you have no problem using these versions):

Rasa Version     : 2.8.0
Rasa SDK Version : 2.8.0
Rasa X Version   : 0.41.2
Python Version   : 3.8.0
Operating System : Windows 10

I still recommend to create a backup of your old virtual environment folder just in case.

Sure. thanks. NIK. Will update you here after sometime. Thanks for you response.

@ChrisRahme Thanks buddy, for this information and clarity. I never used with this - i , as I not much work on Rasa-X. But, I noted :wink:

Sure. I don’t need old env. It was just for testing purpose. We’ll redo the same. will update here may be tomorrow my morning time (i.e. IST timezone)

@sharifm Do follow both process/suggestions separately don’t make the cocktail of code :stuck_out_tongue: Good Luck!.

Haha yup

I suggest trying @nik202’s solution first because the downloads in my solution are pretty big.

This solutions didn’t work. I executed all the steps mentioned above, I don’t think “rasa x : version 0.41.2” is compatible with Sqlalchemy library version " 1.4.22". PFA doc for more details. rasa_x_0-41-2__issue.txt (12.2 KB) Rasa x failed to start with same reason as before , see below I will uninstall current "rasa x : version 0.41.2 and try version 0.32.0 as mentioned in Installing Rasa X Locally on Windows 10 - YouTube

@sharifm Please downgrade rasa x to 0.39.3 with compatible version of rasa and rasa-sdk; it can be 2.8.0 and 2.8.1 or as per compatibility your wish. Python Verison can be 3.8.8. it will surely solve your issue.

Some errors and its solution if encountered:

error: ImportError: cannot import name ‘RowProxy’ from ‘sqlalchemy.engine’ try running pip install SQLAlchemy==1.3.22 should fix it.

import yaml then run pip install pyyaml

Can come some errors, but now I am sure you will handle them well :slight_smile: This is the clean execution. Good Luck!

If any error, please share with us.

Now getting another error, ACCESS DENIED

ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: ‘C:\Users\JS\AppData\Roaming\Python\Python38\site-packages\_ruamel_yaml.cp38-win_amd64.pyd’ Check the permissions.

Qn - How come other pkg installed previously (like rasa & rasa-sdk)

@sharifm your rasa-sdk is 2.8.0 first change to pip install rasa-sdk==2.8.1; Try install to latest please.

@sharifm This is not related to rasa its environment permission and pip issue.

@sharifm Are you using conda shell which have administrative privileges?

@sharifm

pip install rasa-x==0.39.3 --extra-index-url https://pypi.rasa.com/simple OR pip install --user rasa-x==0.39.3 --extra-index-url https://pypi.rasa.com/simple

Its 2.8.0 which you and chris suggested in above post.
