Hi,
you can not simply fetch files from your file system in the browser. That's why you get this error.

Either host your model file on localhost via an express server for example, or implement a filepicker to upload the model file.

Hi,
Why i can not ? either the same page works fine in Firefox !
and sorry for this question but "Either host your model file on localhost via an express server for example, or implement a filepicker to upload the model file." i don't get it and how i can do that i am a beginner in js ...
ps: this page is hosted in localhost

Hmm, that's odd. Usually browsers don't allow you to access files from your filesystem for security reasons, that's why the fetch request in model.load is failing in chrome (not sure why this works for you in firefox).

If you look at my examples in this repo, you can see that I state, which folders can be publicly accessed (in server.js). This way you can load your model from an url e.g. net.load('models/my-model'). You can do the same for your model.

With filepicker I mean, you can use an input element of type 'file', which is another way to browse and load files from your browser. There should be plenty of tutorials out there, explaining how to implement a file upload.

okey thanks a lot for your explanation and for the second : a web page slows down your browser" and blocks the browser :

Isn't this just a warning? When exactly does this appear, when loading the model or during inference?

Edit: I think this just pops up when the event loop is blocked for some amount of time, essentially saying, that the main thread is not reacting to any interaction while blocked.

yes it is just a warning and it happen during loading the model !
