Please help in resolving import of tesseract
What steps will reproduce the problem?
1. Install tesseract-ocr, leptonica-1.69 and python-tesseract from source
2. import tesseract from script
3. Also readText method from simplecv fails with " SimpleCV:2: 'Please
install the correct OCR library required -
http://code.google.com/p/tesseract-ocr/
http://code.google.com/p/python-tesseract/'
What is the expected output? What do you see instead?
script should be able to import tesseract
What version of the product are you using? On what operating system?
Fedora18
tesseract-ocr, leptonica-1.69 and python-tesseract from source
Please provide any additional information below.
