Question

Opencv 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 1

After 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.
