I got this error because I installed pytesseract
with pip
but forget to install the binary.
On Linux
sudo apt update
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev
On Mac
brew install tesseract
On Windows
download binary from https://github.com/UB-Mannheim/tesseract/wiki. then add pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'
to your script. (replace path of tesseract binary if necessary)
