Using certain traindata files causes Tesseract crash.

[oldominion]

I've cross posted this on the github page of the traindata files.

Shreeshrii/tessdata_shreetest#7

Using any of these lang files (see: https://github.com/Shreeshrii/tessdata_shreetest) cases tesseract via EmguCV 4.1 it to fail with:

"DotProductAVX can't be used on Android"

I'm building my application for Windows x64 target platform.

This isn't a new issue by any means:

tesseract-ocr/tesseract#1113
tesseract-ocr/tesseract#1151

Someone else having this same problem: http://www.emgu.com/forum/viewtopic.php?t=21084

Found a workaround is to convert the traineddata file to integer type with --convert_to_int

This reduces accuracy as far as I understand, so it would be preferable if EmguCV could fixed to work with float type traindata files too.

Does anybody know how to fix the bug? I can not update to Emgu 4.x because i need tesseract to run with float type traindata files. But I would like to work with the newes version.

@oldominion can you please provide file which you converted to integer type also let us know how you have used. we are having same issue with following code we are getting OOM Killed error string result; using (Tesseract ocr = new Tesseract(TessdataPath, "eng", OcrEngineMode.TesseractLstmCombined)) { ocr.PageSegMode = PageSegMode.SingleBlock; ocr.SetImage(gemImg); result = ocr.GetUTF8Text().Trim().TrimStart('-'); result = Regex.Replace(result, @"[^0-9a-zA-Z-]+", ""); } gemImg.Dispose(); return result;
