I have a problem when I use the pytesseract library with python
I'm on macOS Catalina 10.15.5
And I'm using an environment to run openCV Library and it works just fine, I installed pytesseract using homebrew using this command - with the environment active -:
brew install tesseract
and I checked the version of tesseract it shows v4.1.1
So I'm not sure where is the mess up

I have downloaded Anaconda on my Windows PC, and I have been using Spyder IDE. Now I want to do a project with OpenCV.
However, I have tried to install OpenCV using the Command Prompt and typing the following in:
pip install opencv-python
This only gives an error message and says "pip" is not recognized as a command.
Furthermore I tried to import OpenCV into Python using the following:
import cv2
This also doesn't work
I would appreciate any help in getting OpenCV working.
It depends on Your OS. Check Your pip installation with cmd: pip -V and check python with: python -V
It seems like You don't have pip installed at all.
Than import cv2 should work.
I have installed Anaconda 2018.12 (Python 3.7 version). I am trying to test out the pytesseract module but I keep encountering:
TesseractNotFoundError: C:\Program Files (x86)\Tesseract-OCR\tesseract.exe is not installed or it's not in your path
I have done:
pip install Pillow (already installed it says)
pip install pytesseract (successful)
Tried to set the tesseract_cmd to the location of tesseract (but I can't find it)
I have searched for the tesseract.exe file but cannot find it anywhere on the system so I'm struggling to understand how do I reference/import the module into a jupyter notebook if it's already been consumed into anaconda?
The code I'm trying to run is:
from PIL import Image
import pytesseract
#pytesseract.pytesseract.tesseract_cmd = r"C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe"
text = pytesseract.image_to_string(Image.open('C:\Temp\IMG_1519.jpg'))
print(text)
I'm hoping it's simple user error but any assistance would be gratefully received. Many thanks, Ben
Quoting from the PyPi page:
Python-tesseract is a wrapper for Google’s Tesseract-OCR Engine.
and (under prequisites):
Install Google Tesseract OCR (additional info how to install the engine on Linux, Mac OSX and Windows)
This means, that pytesseract is not a standalone module. It is a python wrapper for using the Google’s Tesseract-OCR Engine, which you need to install seperately
I've successfully running Python 2.7.15 (default one) on macOS Sierra 10.12.6.
I have also installed OpenCV using pip of version 3.4.0, using this tutorial.
Screenshot: Python IDLE Screenshot showing OpenCV version on macOS
When I try to import cv2 from python IDLE it gets successfully imported, but when I try import cv2 from a python script and run as cgi script, it shows the following error:
Error Screenshot: OpenCV import error while importing and running from browser
What does the error actually mean?
How can I solve this?
Note: I've no errors while running python as CGI scripts (without importing opencv).
Note: I've even tried of installing OpenCV using Homebrew but it still produces the same error while importing OpenCV as a CGI script.
Very common error with OpenCV, the best move you can do is to install OpenCV using Anaconda.
I recommend you to fully uninstall Python and install Anaconda Python, it comes with the conda package manager that will allow you to install opencv--python easily.
https://www.anaconda.com/download/
Once Anaconda Python is installed, try the following commands:
conda install -c conda-forge opencv
conda install -c menpo opencv3
My objective is to use OCR in Python 2.7 using Tesseract on a Windows 7 machine, but I am running into issues as for the installation process. I tried following the instruction here but the link to "tesseract-core-yyyymmdd.exe" and "tesseract-langs-yyyymmdd.exe" do not exist anymore and I can't find these .exe elsewhere online. Here's what I have done so far:
installed tesseract from its executable from official tesseract-ocr page.
installed via pip packages "wand", "PIL", "pyocr".
Now, if I do the following in Python:
from wand.image import Image
from PIL import Image as PI
import pyocr
import pyocr.builders
import io
No problem loading up these packages but pyocr.get_available_tools() gives me an empty list. I am sure this has to do with the missing installation .exe files above. Where can I find them? Is it something else that I am missing?
I just tried to set up pytesseract and it works ! I have windows 10 and python 2.7 installed.
all you need to do :
Download Visual basic C++ from http://aka.ms/vcpython27 and install it (common installation step)
Download tesseract from python via this link https://pypi.python.org/pypi/pytesseract
Unizip the file.
Go to the directory which contains the unizip file
Run this command " python setup.py install "
(Additional) to test if it's installed, go to your python shell and run this command " import pytesseract "
I hope it works !! Note pytesseract is google based OCR, it works similarly to tesseract.
Step [1] To install tesseract kindly visit
https://github.com/UB-Mannheim/tesseract/wiki
The latest installers can be downloaded from here:
e.g., tesseract-ocr-setup-3.05.02-20180621.exe, tesseract-ocr-w32-setup-v4.0.0-beta.1.20180608.exe, tesseract-ocr-w64-setup-v4.0.0-beta.1.20180608.exe (64 bit)
Step [2] Download Microsoft Visual C++ Compiler for Python 2.7 from the link given below
https://download.microsoft.com/download/7/9/6/796EF2E4-801B-4FC4-AB28-B59FBF6D907B/VCForPython27.msi
Step [3] Install pytesseract for binding for tesseract using pip
pip install pytesseract
Step [4] Furthermore you can install an image processing library in python, e.g., pillow:
pip install pillow
greetings!! you are done!! :)
PIP is a package manager for Python packages
Open cmd run pip search "pytesseract", you can see latest version
Run pip install pytesseract for latest version or pip install pytesseract==0.3.0 for version you want.
In windows python cmd run import pytesseract for sure installed was successful.
Install both and you are done

How can you import OpenCV to run in Python?
I ran it on a windows platform. My main problem i ran into was using Python 3.5 (presuming it was the latest) and the latest version of OpenCV but i didn't know that OpenCV sis not compatible with Python 3.5 so online video tutorials on youtube all failed miserably and i couldnt get past the import stage for almost a full day.
Here's what I have tried:
Python 3.5 (64bit) & (32bit) with OpenCV
Anaconda 3 (64bit) & (32bit) with OpenCV
Using Anaconda Python 2.7 (64bit) with OpenCV ended up working. Turns out OpenCV that I downloaded from the site is for Python 2.7.
conda install -c menpo opencv3=3.1.0
or
conda install -c anaconda opencv=2.4.10
It's a bit annoying that you need to know which collection a package is in if it isn't the standard one, but a certain search engine will find it.
you can simply activate your conda environment
conda activate "environment name"
install opencv using pip
pip install opencv-python
simply compile your code in your environment it should work
it should work.
