@greenbreakfast I followed the setup instruction, installed and ran smoothly!
@VSemi-Zhen you may also have a try?

[greenbreakfast]

@VSemi-Zhen please try it out and let us know how it goes!

there should be a python download link in the instruction
I recommend the following text.

To use the Tau Studio Web App, you'll need to have Python and TauLidarServer installed.

1. install python
   Download and install python at https://www.python.org/downloads/. Make sure you install version 3.6.1 or higher. If you
   have questions about python installation, further instructions can be found at the official Python.org instructions 
2. install TauLidarServer Python module
   Open a command-line window, and run the following command:
   python -m pip install TauLidarServer
