Tesseract running error

Question

I have a problem with running tesseract-ocr engine on linux. I\'ve downloaded RUS language data and put it to tessdata directory (/usr/local/share/tessdata). When I\'m tryin

Answer 1

tesseract  --tessdata-dir   stdout --oem 2 -l 

In my case, the mistakes that I've made or attempts that wasn't a success.

• I cloned the github repo and copied files from there to
  • /usr/local/share/tessdata/
  • /usr/share/tesseract-ocr/tessdata/
  • /usr/share/tessdata/
• Used TESSDATA_PREFIX with above paths
• sudo apt-get install tesseract-ocr-eng

First 2 attempts did not worked because, the files from git clone did not worked for the reasons that I do not know. I am not sure why #3 attempt worked for me.

Finally,

1. I downloaded the eng.traindata file using wget
2. Copied it to some directory
3. Used --tessdata-dir with directory name

Take away for me is to learn the tool well & make use of it, rather than relying on package manager installation & directories
