I was following this guide https://realpython.com/blog/python/setting-up-a-simple-ocr-server/ and got to the part where I run cli.py
Traceback (most recent call last):
File "cli.py", line 3, in <module>
ImportError: No module named pytesseract
import errors usually boils down to one of those three cases (whether is is modules you developed; or modules distributed as packages):
You did no install the required package. Googling
pytesseracttells me its an OCR that is distributed and installable using Python package manager tool
pip by running
pip install pytesseract in your favorite shell.
You did install the package, but is is not in your python path.
(Less often) You did install the package, and it is in your python path, but you used a name already in user by Python, and the two are conflicting.
In your case, I strongly think this is the first one. Case 2. and 3. can be assessed by calling
python -v your_script.pyas described in this answer.
