Error loadModel

[ran-j]

I download from 'Word2Vec' http://nilc.icmc.usp.br/embeddings

this http://143.107.183.175:22980/download.php?file=embeddings/word2vec/cbow_s50.zip

And try to load

var w2v2 = require( 'word2vec' );
w2v2.loadModel( 'C:\Users\Ranieri\Documents\Projetos\playground\datas.txt', function( error, model ) {
    console.log(error)
    console.log( model );
});

but nothing happens

Node 8.11

Add some logging to the node_modules/word2vec/lib/model.js file and you might find some answers. My issue was that I was trying to load a .json file. The init function has a switch statement with no default case. I added a default case to throw an error. Try this.

	function init( file ) {
		var mime_type = mime.getType( file );
		switch ( mime_type ) {
			case 'text/plain':
				console.log('File type is text/plain')
				readTxt( file );
			break;
			case 'application/octet-stream':
				console.log('File type octet-stream')
				readBinary( file );
			break;
			default: throw new Error( 'Invalid file type!' );
		}
	}
	init( file );

@Mattperkinsee Please respect the callback and don't just throw your own errors, since the callback explicitly defines it:

Thanks for the info. I installed from npm and my model.js file didn't have a default case which I assumed might occur with others. My package.json file shows version 1.1.5. What am I missing?

@Mattperkinsee loadModel takes a callback and calls it with (error, model), which is not given with your code.

So you raise an error, but then have to catch it via try/catch and cannot rely on the given API just in that error case.

Just pointing out the existing API, good that you got it to work!
