how to configure python in rapidminer

Hey @sulabh

Did you try this documentation https://docs.rapidminer.com/latest/studio/installation/python-scripting-extension.html?
If you are using anaconda Rapidminer can easily locate all your environments given you have added conda to the path.

somehow anaconda is not being installed successfully on my system. what could be the reason

Probably you might not have added conda to path during installation. Check this stack overflow post to add to path. 
If that does not work, your best bet could be to reinstall, if you have specific environments setup you can backup them as yml files.

thanks for the guidence

i am facing problem while installing anaconda. The error message are attached herwith for your consideration. please help where lies the fault

I think there is some issue with purging the previous files of old installation or the permissions to add path variable in the windows. The best could be to remove the installation folders and all temp files (Use Windows Explorer to delete the envs and pkgs folders prior to running the uninstall in the root of your installation).

tried everything but the problem persists. please guide

Do you have consistent errors still? Please PM me and we can see how I can help you out of the issue.
