Tesseract.js and traineddata language.

[Clint William Theron]

Hey. I started a Gitpod and build a tesseract.js app on a node.js server using this tutorial. I now want to use my own custom traineddata language file.  I imagine I should copy my trained file somewhere in to the project but I'm not sure. I tried replacing the eng.traineddata file located in /tests/assets/traineddata/ but, in windows 10, that didn't work. What should I do? Any advice would be greatly appreciated.

Thanks

just give me clue!

Thank you. I truly appreciate it. It's coming up with the most efficient search term, that's the key.

Actually, that doesn't answer my question. It only says where tesseract stores the .traineddata file after download and not how to set the langPath. I tried to set the langPath like this:

const worker = new TesseractWorker({
 corePath: '../../node_modules/tesseract.js-core/tesseract-core.wasm.js',
 langPath: lang_path
 });


worker.recognize(file,
        'cus'
    )
        .progress(function(packet){
            console.info(packet)
            progressUpdate(packet)

        })
        .then(function(data){
            console.log(data)
            progressUpdate({ status: 'done', data: data })
        })

but I get errors: 

* Error opening data file ./cus.traineddata

* Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.

Thanks for anything...

Intuitively I know it answers my question but I fail to see the answer. Here's what went through my mind as I read your link: "I think a gitpod is a node.js server so that means the file shuld be in the fs where the command was executed. The command got executed in the demo.html file which is located in the browser directory but there is no .traineddata in that folder. maybe the command got executed in the /dist directory because at the beginning of the script we included the following

<script src="/dist/tesseract.dev.js"></script>

but if so I don't see the directory in the project..."

it's about here where I get lost. I now think maybe I should declare the langPath but this I did and I already told you what happens...

guys help me out here because after I get this right I still need to work on my .traineddata file itself. It's working but it's limited. I just made it to get started...

Thanks already :-)

Why don't you ask questions over there?  I guess you've been advised so.
