Can it be used on Windows?

I have try the command line on Windows， it does not work.

D:\MyGithub\ocrd-train-master>  make leptonica tesseract langdata
wget 'http://www.leptonica.org/source/leptonica-1.76.0.tar.gz'
process_begin: CreateProcess(NULL, wget http://www.leptonica.org/source/leptonica-1.76.0.tar.gz, ...) failed.

We only develop for Ubuntu Linux at the moment. @UB-Mannheim maintains a Windows installer for tesseract 4. I'm not sure whether it bundles the training tools though.

You could try to compile this within cygwin or Win10's bash environment, not sure how compatible these are with native Linux though.

The first error is because you're missing wget in your path.

The second error is because file in Python 2 is mostly synonymous with open but is gone as a global keyword in Python 3 which you seem to be using. This we will fix, I'll open an issue.

Thank you! I have tried with Ubuntu and it work well.

At the moment, no plans for Windows support.
