Thanks for raising this issue, @erohmensing will get back to you about it soon.

Hi @ArupMukherjee, do you have the Windows requirements installed?

Looks like you use anaconda, maybe this is helpful: https://stackoverflow.com/questions/39020361/python-scipy-module-import-error-due-to-missing-ufuncs-dll/39021044#39021044

[ArupMukherjee]

Thanks @erohmensing , @akelad for your responses. I was able to navigate past the errors by creating a virtual python environment using python = 3.6, My anaconda python = 3.7 was giving me issues.

[erohmensing]

Hm that's strange, 3.7 should be supported, but we can look into making sure it is supported as expected on windows. Glad you were able to get past the errors.

@ArupMukherjee Could you please try uninstalling / installing scipy in your 3.7 environmet?

[narasivenkat]

For windows, visual studio 19 needs to be installed. Once done rasa init --no-prompt works fine for python 3.7. tensorflow 2.1 as well.
