Summary

pytesseract.pytesseract.TesseractNotFoundError: This app has encountered an error. The original error message is redacted to prevent data leaks. Full error details have been recorded in the logs (if you're on Streamlit Cloud, click on 'Manage app' in the lower right of your app).

pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your PATH. See README file for more information.

Steps to reproduce

Code snippet:
import pytesseract
plate = pytesseract.image_to_string(threshold, config='-c tessedit_char_whitelist=0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ --psm 8')

(Please provide a code snippet! This will help expedite us finding and solving the problem.)

Debug info

Requirements.txt is given below
imutils==0.5.4
numpy==1.21.2
opencv-python-headless
Pillow==9.0.0
streamlit==1.6.0
tesseract
pytesseract

Additional information

Tesseract not found error pops up in Streamlit when I try to run any function of pytesseract.On local device the same error is fixed by adding a path to the tesseract library but on Streamlit tat can not be done as the backend server where the library is being imported from path is not public.

Hi @abhay-lal,

The installation instructions for pytesseract say that Google's tesseract-ocr is a dependency. Meaning, you need to install tesseract-ocr as an apt-get dependency (for Linux applications outside the Python environment).

The way to do that is to include the necessary dependencies in a packages.txt file in your repo:

1. Create a new packages.txt file with the following line:

   tesseract-ocr
   

2. The first line installs the base tesseract-ocr application and supports only English by default. To support other languages, you need to install a language specific tesseract data file, which you can do in subsequent lines in packages.txt.

3. Reboot your app

Once you make the above changes, your app should successfully deploy! 🎉
