Javascript 在tesseract.js中加载脱机lang数据

我正在尝试将自己经过训练的数据加载到tesseract.js。由于文件放在本地，我尝试脱机加载所有内容。我使用的代码如下所示：

<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>

我在/traineddata文件夹中有eng.traineddata和eng.traineddata.gz，因为显然取消压缩过程被跳过。有什么我忽略的吗？感谢您的帮助

我知道这个问题很老，但最近我需要在我的一个项目中使用Tesseract.js。我需要在本地加载数据文件，所以这里是我所做的

而不是创建一个新的工作者。我修改了可用的默认辅助选项。因此，我没有使用Tesseract.createWorker，而是直接设置路径并使用recognize

 Tesseract.workerOptions.langPath = 
           window.location.origin // take protocol://domain.com part
           + "/scripts/tesseract/dist/"; // location of data files

 //you could set core and worker paths too but I didn't need it
 Tesseract.workerOptions.workerPath = 
           window.location.origin // take protocol://domain.com part
           + "/scripts/tesseract/dist/worker.js"; // location of worker.js

 //you could set core and worker paths too but I didn't need it
 Tesseract.workerOptions.corePath = 
           window.location.origin // take protocol://domain.com part
           + "/scripts/tesseract/dist/index.js"; // location of index.js

//example lang path would be protocol://domain.com/scripts/tesseract/dist/

通过这样做，我保持了指向默认CDN的工作路径和核心路径不变

PS：当使用本地worker.js和core.js路径时，我在worker.js中的postMessage（）上发现了未捕获的错误。这就是为什么我只对langData使用本地路径。我仍然不知道如何修复它，也不知道它为什么会发生。但是，您可以关注这个问题，我通过从

和来自

的语言gz嗨，你找到了解决问题的方法吗？我也面临着类似的问题。这在任何意义上都不是一个解决方案，但我将数据转换为blob并将其放入js文件中以加载它。所以tesseract索引文件是否能够读取该blob文件并给出正确的输出？无论如何，我能够在本地加载语言文件，它现在对我来说工作正常。
