Opencv facing an error for tesseract moule not found even after installations
Asked 2022-Feb-01 at 14:04Opencv facing an error for tesseract moule not found even after installations
pip install tesseract
opencv reinstallation also done but it wont work.
opencv installation commands are
pip install opencv-python
pip intstall opencv-contrib-python
tesseract.exe installtion using this github guidance -link
Still iam facing this below error
error - tesseract module not found

ANSWER
Answered 2022-Feb-01 at 14:04After fixing this error working fine changing file path (C:\Program Files(x86)\Tesseract-OCR\tesseract.exe) to ->(C:\Program Files\Tesseract-OCR\tesseract.exe)
Whatever your path in windows programfiles, do not use a Program Files(x86) it wont work
Still showing or not installing error you are facing then press windows + R keys and run your file path (C:\Program Files\Tesseract-OCR\tesseract.exe) it wil work for me,
This mentioned error had fixed - tesseract module not found
Hope it will help some one.
