[p5 library - YOLO / Web works well, but does not work in p5.]

hello.

1. Source code running on the web  
[https://editor.p5js.org/ml5/sketches/ObjectDetector\_YOLO\_single\_image](https://editor.p5js.org/ml5/sketches/ObjectDetector_YOLO_single_image)

It works fine.

1. If you copy the WEB source code as it is and run it with ‘Processing-P5’,  
Does not.  
(An error appears as shown in the figure.)  
What’s the reason?

> The problem is that browsers block loadings from “file://” scheme. You’re gonna need some local server in order to run “.js” scripts as “http://” scheme instead. Alternatively, you can install Firefox: Once installed, go to its about:config page. Then at the search box there, type in privacy.file\_unique\_origin, and toggle it to false. Now you can run most sketches from there via the “file://” scheme.
