shit shit and shit
## 4.0 +
Tesseract 4.0 **+** source code is available in the 'master' branch of the [repository](https://github.com/tesseract-ocr/tesseract). It adds a new OCR engine based on LSTM neural networks. It initially works (well) on x86/Linux. Model data for 101 languages is available in [tessdata](https://github.com/tesseract-ocr/tessdata), [tessdata_best](https://github.com/tesseract-ocr/tessdata_best), [tessdata_fast](https://github.com/tesseract-ocr/tessdata_fast) repositories.

Leptonica 1.74.1 package for Debian:
* https://packages.debian.org/sid/libleptonica-dev
## 4.x for Windows
Unofficial experimental binaries of tesseract-ocr 4.x are available from the following links. Each one is from a different commit from master branch in early 2017. See individual sites for more details:
* [Windows Installer made with MinGW-w64](http://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-setup-4.00.00dev.exe) from [UB Mannheim](https://github.com/UB-Mannheim/tesseract/wiki)
* [zip file with cppan generated .dll and .exe files](https://www.dropbox.com/s/obiqvrt4m53pmoz/tesseract-4.0.0-alpha.zip?dl=1), You have to install VC2015 x86 redist from microsoft.com in order to run them.
* [Win64 build of tesseract 4.0.0 alpha, leptonica 1.74.1, and charlesw/tesseract .Net wrapper](https://github.com/tdhintz/tesseract4win64) - built using CPPAN for Visual Studio 2017.
## 4.x with GUI frontend
### VietOCR
[Windows binaries of tesseract-ocr 4.0.0-alpha with GUI interface are available for VietOCR](https://sourceforge.net/projects/vietocr/files/vietocr/) from
* [VietOCR5.0alpha](https://sourceforge.net/projects/vietocr/files/vietocr/5.0alpha/)
* [Visual C++ Redistributable for Visual Studio 2015 runtime - vc_redist.x86.exe](https://www.microsoft.com/en-us/download/details.aspx?id=48145) is REQUIRED for VietOCR to run correctly.
VietOCR can be used to download appropriate 4.0.0alpha traineddata for additional languages.
### gImageReader
[Windows binaries of tesseract-ocr 4.0.0-alpha with GUI interface are available for gImageReader](https://github.com/manisandro/gImageReader/releases) from
* [gImageReader_3.2.1_qt5_i686_tesseract4.0.0.git2f10be5.exe](https://github.com/manisandro/gImageReader/releases/download/v3.2.1/gImageReader_3.2.1_qt5_i686_tesseract4.0.0.git2f10be5.exe)
* [gImageReader_3.2.1_qt5_x86_64_tesseract4.0.0.git2f10be5.exe](https://github.com/manisandro/gImageReader/releases/download/v3.2.1/gImageReader_3.2.1_qt5_x86_64_tesseract4.0.0.git2f10be5.exe)
Download 4.0.0alpha traineddata to use with the above from master branch of tessdata. e.g. for Hindi download the following file:
