I am trying to load my own trained data to tesseract.js. As the file is placed locally, I tried to load everything offline. The code I used is shown below:
<script src="tesseract.js"></script>
<script>
//Set the worker, core and lang to local files
(function() {
var path = (function() { //absolute path
var pathArray = window.location.pathname.split( '/' );
pathArray.pop(); //Remove the last ("**.html")
return window.location.origin + pathArray.join("/");
})();
console.log(path);
window.Tesseract = Tesseract.create({
workerPath: path + '/worker.js',
//langPath: path + '/traineddata/',
corePath: path + '/index.js',
});
})();
</script>
<script>
function recognizeFile(file){
document.querySelector("#log").innerHTML = ''
Tesseract.recognize(file, {
lang: document.querySelector('#langsel').value
})
.progress(function(packet){
console.info(packet)
progressUpdate(packet)
})
.then(function(data){
console.log(data)
progressUpdate({ status: 'done', data: data })
})
}
</script>
The code above is working fine if the langPath is not set, but when I point the langPath
to a local folder, Tesseract failed to load anything with the following error:
Failed loading language 'eng'
Tesseract couldn't load any languages!

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.

I have both eng.traineddata and eng.traineddata.gz in the /traineddata folder as apparently the ungzip process is skipped. Is there anything I neglected? Any help is appreciated.
