Hello, I am fairly new to Rasa and am trying to setup version 1.5 on a Jetson Nano. I have successfully installed Rasa 1.5, but upon running ‘rasa init’ I receive the following: "Welcome to Rasa! :robot: To get started quickly, an initial project will be created. If you need some help, check out the documentation at Introduction to Rasa Open Source. Now let’s start! :point_down:t4: ?

Please make sure the name is a valid policy." Does anyone know what could be causing this issue? I’m using Tensorflow1.15.4+nv20.12 and python 3.6, so I’m not too sure what’s causing this issue.

Nevermind, I have fixed this error. It turns out this was due to me using a version of Tensorflow Datasets that was too recent. I switched to Tensorflow Datasets version 3.2.1 and now it is working fine :slight_smile:

@abb That’s great! Congratulations. I’d still encourage to install rasa latest version.

@nik202 If there is a way to install the latest rasa version on Jetson Nano, I’d be more than happy too! At the moment though I’m not sure if it is possible, as Rasa 2.x requires tensorflow-addons, which I don’t think is available on Jetson Nano.

@abb Oh, I see NVIDIA Jetson Nano what is your configuration?
