Neural networks require significantly more training data and train a lot slower than base Tesseract. For Latin-based languages, the existing model data provided has been trained on about textlines spanning about fonts.

For other scripts, not so many fonts are available, but they have still been trained on a similar number of textlines.

Even with all this new training data, you might find it inadequate for your particular problem, and therefore you are here wanting to retrain it.

I'm looking to get away from Homestead but want to be sure Laragon is workable. Is it possible to install other programs on Laragon. For example, I require Beanstalk. I'd also need to install Tesseract OCR. I was able to install Tesseract OCR via node. As for Beanstalk, I can't really speak to that because I'm not that familiar with it, but you should be able to use any IDE or code editor you want with Laragon without any issues.

I use Visual Studio Code, for example, and it works perfectly with Laragon. If Beanstalk comes with its own terminal, then you should able to use that if you want as well, though Laravel has it's own preconfigured terminal solution that you can configure to your liking as well depending on whether you prefer to use PowerShell, bash, CMD, CygWin, etc. Looking for industry-tier cloud hosting at a fraction of the cost? Thanks Max. Beanstalk is a work queue for passing off jobs in the background.

In production, we have some lengthy jobs that run over night using the queue. I'm curious what you meant by installing Tesseract via nodejs. I see a npm package for it, but it still needs the project to be installed. However, you can install only Beanstalk using VM or Docker. Yeah, fair enough, I did have to install some extra dependencies along with Tesseract it was a small project I did a few months ago and haven't touched sincebut, from what I recall, it was fairly seamless.
