Help with Live Demo

[WaltPeter]

Hi,
I tried to open the live demo from the link https://modeldepot.github.io/tfjs-yolo-tiny-demo/ ,
but it's not working. No detection is made, and I waited for minutes. I check the Chrome console and it gives me error:

C:\fakepath(142,7-116): warning X3569: loop executes for more than 255 iterations (maximum for this shader target), forcing loop to unroll

Warning: D3D shader compilation failed with default flags. (ps_3_0)

I don't know what is went wrong.
I am using Windows 7 latest Chrome to browse the live demo, without a GPU on my PC.
Perhaps it is because of I didn't have a GPU?
I need to confirm it.
Thank you.

can you provide where the error is coming from? specific file name or trace stack ?

Sorry for the "non-specific". I am too dumb that I actually how it works.
Somehow, the error is come from "https://modeldepot.github.io/tfjs-yolo-tiny-demo/src.367e2190.js"
