Adding the extension to a MakeCode project fails

microbit-carlos commented 1 month ago

Trying to add this extension to a project in the online MakeCode editor doesn't show the extension:

Looking at the dev tools console we can see the following errors:

pxtapp.js:1 
 GET https://pxt.azureedge.net/api/gh/microbit-foundation/pxt-ml-runner-poc?cdn=20240517 404 (Not Found)

pxtapp.js:1 Error: Bad HTTP status code: 404 at https://pxt.azureedge.net/api/gh/microbit-foundation/pxt-ml-runner-poc?cdn=20240517; message: {"message":"maximum file size in package is ~128k; file model-example/model_example.c; size 175979"}
    at pxtapp.js:1:66758
    at async E (pxtapp.js:1:209588)
    at async Promise.all (index 0)

The specific error message being:

maximum file size in package is ~128k; file model-example/model_example.c; size 175979

While the extension is quite large, as the embedded ML model is ~56KBs, I wouldn't have expected it to be larger than 128KBs, or around 175KBs as indicated by the error.

Building locally without BLE results in a binary that is ~200 KBs in total (not just the extension), so maybe MakeCode is confusing that full size?

Workaround

Rather than loading the extension via the GH URL, you can build the extension locally and drop the hex file into the editor.

This can be close as resolved as the built-in model has been changed to a smaller one.

microbit-foundation / pxt-ml-runner-poc
