Just hit the same error and decided to answer this question – it might help someone to save time…
First, make sure you have installed/copied Tesseract-OCR executables.
Windows can’t find the executable tesseract
in the directories specified in your PATH
environment variable. So either make sure that the directory containing tesseract
is in your PATH
variable or overwrite tesseract_cmd
variable in your Python script like as following (put your PATH instead):
import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract'
Beside that make sure that TESSDATA_PREFIX
Windows environment variable is set to the directory, containing tessdata
directory. For example:
TESSDATA_PREFIX=C:\Program Files (x86)\Tesseract-OCR
if tessdata
location is: C:\Program Files (x86)\Tesseract-OCR\tessdata
