It seems that I did not install pyOCR correctly, because I get an empty list when I do:
import pyocr.builders pyocr.get_available_tools()
Any ideas?
I installed pyOCR in the environment via pip:
pip install pyocr
EDIT
The following performed the trick.
sudo apt-get install tesseract-ocr sudo apt-get install tesseract-ocr-eng sudo apt-get install tesseract-ocr-ell
