Hello @desnug1,

I’ve have not played with the mobile client locally, I usually just use the version provided from the studio

I’ve just been through the code and I’ve seen this line:

github.com

edgeimpulse/mobile-client/blob/master/client/classification-loader.ts#L71

      
        
            this.emit('status', 'Received blob (' + Math.floor(blob.size / 1024) + ' KB), extracting...');
            
            
const data = await this.unzip(blob);
            
            
this.emit('status', 'Extracted ' + data.length + ' files');
            
            
console.log('Extracted files', data);
            
            
let wasmFile = data.find(d => d.filename.endsWith('edge-impulse-standalone.wasm'));
            if (!wasmFile) {
                wasmFile = data.find(d => d.filename.endsWith('.wasm'));
                if (!wasmFile) {
                    throw new Error('Cannot find edge-impulse-standalone.wasm file in ZIP file');
                }
            }
            
            
let jsFile = data.find(d => d.filename.endsWith('edge-impulse-standalone.js'));
            if (!jsFile) {
                jsFile = data.find(d => d.filename.endsWith('.js'));
                if (!jsFile) {
                    throw new Error('Cannot find edge-impulse-standalone.js file in ZIP file');

I just want to make sure that you can see the .wasm file somewhere locally?

Also feel free to share the console output.

Regards,

Louis

hi @louis
I think the problem is:

edge-impulse-standalone.wasm 404 (File not found)

also I can’t find .wasm file in my locally…
its weird, since 2 month ago I can run smoothly…

Updated:
I think I know how to fix this, I have to download manually from

https://studio.edgeimpulse.com/v1/api/projectID/deployment/download?type=wasm&modelType=float32

and put the wasm file into public folder.

but still, its weird since 2 or 3 month ago I dont have to download and put manually on the local folder…

regards,

desnug

Hello @desnug1,

Glad that you solved your issue. I don’t see it either a default model in the public folder but I don’t remember if it actually ever existed.
I’ll try to update the README.md of the Github project so it’s clearer in the future how to do so.

Regards,

Louis
