[python] Pytesseract : "TesseractNotFound Error: tesseract is not installed or it's not in your path", how do I fix this?

I'm trying to run a basic and very simple code in python.

from PIL import Image
import pytesseract

im = Image.open("sample1.jpg")

text = pytesseract.image_to_string(im, lang = 'eng')


This is what it looks like, I have actually installed tesseract for windows through the installer. I'm very new to Python, and I'm unsure how to proceed?

Any guidance here would be very helpful. I've tried restarting my Spyder application but to no avail.

This question is related to python tesseract

The answer is

I see steps are scattered in different answers. Based on my recent experience with this pytesseract error on Windows, writing different steps in sequence to make it easier to resolve the error:

1. Install tesseract using windows installer available at: https://github.com/UB-Mannheim/tesseract/wiki

2. Note the tesseract path from the installation. Default installation path at the time of this edit was: C:\Users\USER\AppData\Local\Tesseract-OCR. It may change so please check the installation path.

3. pip install pytesseract

4. Set the tesseract path in the script before calling image_to_string:

pytesseract.pytesseract.tesseract_cmd = r'C:\Users\USER\AppData\Local\Tesseract-OCR\tesseract.exe'

First you should install binary:

On Linux

sudo apt-get update
sudo apt-get install libleptonica-dev 
sudo apt-get install tesseract-ocr tesseract-ocr-dev
sudo apt-get 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.

Then you should install python package using pip:

pip install tesseract
pip install tesseract-ocr

references: https://pypi.org/project/pytesseract/ (INSTALLATION section) and https://github.com/tesseract-ocr/tesseract/wiki#installation

For Windows Only

1 - You need to have Tesseract OCR installed on your computer.

get it from here. https://github.com/UB-Mannheim/tesseract/wiki

Download the suitable version.

2 - Add Tesseract path to your System Environment. i.e. Edit system variables.

3 - Run pip install pytesseract and pip install tesseract

4 - Add this line to your python script every time

pytesseract.pytesseract.tesseract_cmd = 'C:/OCR/Tesseract-OCR/tesseract.exe'  # your path may be different

5 - Run the code.

From https://pypi.org/project/pytesseract/ :

pytesseract.pytesseract.tesseract_cmd = '<full_path_to_your_tesseract_executable>'
# Include the above line, if you don't have tesseract executable in your PATH
# Example tesseract_cmd: 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract'

In windows:

pip install tesseract

pip install tesseract-ocr

and check the file which is stored in your system usr/appdata/local/programs/site-pakages/python/python36/lib/pytesseract/pytesseract.py file and compile the file

This error is because tesseract is not installed on your computer.

If you are using Ubuntu install tesseract using following command:

sudo apt-get install tesseract-ocr

For mac:

brew install tesseract

On Mac, you can install it like shown below. This works for me.

brew install tesseract

you can install this package... https://github.com/UB-Mannheim/tesseract/wiki after that you should go this path C:\Program Files (x86)\Tesseract-OCR\ tesseract.exe then run tesseract file. I think this will help you...

On Windows 64 bits, just add the following to the PATH environment variable: "C:\Program Files\Tesseract-OCR" and it will work.

I can solve it by updating the tesseract_cmd variable with the bin/tesseract path in the pytesseract.py file

I had the same issue on Windows. I tried to update the environment variables for the path of tesseract which did not work.

What worked for me was to modify the pytesseract.py which can be found at the path C:\Program Files\Python37\Lib\site-packages\pytesseract or usually in the C:\Users\YOUR USER\APPDATA\Python

I changed one line as per below:

#tesseract_cmd = 'tesseract' 
#tesseract_cmd = 'C:\Program Files\Tesseract-OCR\\tesseract.exe'

Note I had to put an extra \ before tesseract as Python was interpreting same as \t and you will get the below error message:

pytesseract.pytesseract.TesseractNotFoundError: C:\Program Files\Tesseract-OCR esseract.exe is not installed or it's not in your path

For Windows users only:

Install tesseract using:

pip install tesseract

and then add this line to your code, mind the "\"

pytesseract.pytesseract.tesseract_cmd = "C:\Program Files (x86)\Tesseract-OCR\\tesseract.exe" 

You would be needing to install tesseract.


Check out the above documentation on the installation.

In windows, the command path must be redirected, for a default windows tesseract installation.

  1. In 32 bit system, add in this line after import commands.
pytesseract.pytesseract.tesseract_cmd = 'C:\Program Files (x86)\Tesseract-OCR\tesseract.exe' 
  1. In 64 bit system, add this line instead.
 pytesseract.pytesseract.tesseract_cmd = 'C:\Program Files\Tesseract-OCR\tesseract.exe'

Step 1:

Install tesseract on your system as per the OS. Latest installers can be found at https://github.com/UB-Mannheim/tesseract/wiki

Step 2: Install the following dependency libraries using : pip install pytesseract pip install opencv-python pip install numpy

Step 3: Sample code

import cv2
import numpy as np
import pytesseract
from PIL import Image
from pytesseract import image_to_string

# Path of working folder on Disk Replace with your working folder
src_path = "C:\\Users\\<user>\\PycharmProjects\\ImageToText\\input\\"
# If you don't have tesseract executable in your PATH, include the 
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract- 
TESSDATA_PREFIX = 'C:/Program Files (x86)/Tesseract-OCR'

def get_string(img_path):
    # Read image with opencv
    img = cv2.imread(img_path)

    # Convert to gray
    img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

    # Apply dilation and erosion to remove some noise
    kernel = np.ones((1, 1), np.uint8)
    img = cv2.dilate(img, kernel, iterations=1)
    img = cv2.erode(img, kernel, iterations=1)

    # Write image after removed noise
    cv2.imwrite(src_path + "removed_noise.png", img)

    #  Apply threshold to get image with only black and white
    #img = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 31, 2)

    # Write the image after apply opencv to do some ...
    cv2.imwrite(src_path + "thres.png", img)

    # Recognize text with tesseract for python
    result = pytesseract.image_to_string(Image.open(src_path + "thres.png"))

    # Remove template file

    return result

print('--- Start recognize text from image ---')
print(get_string(src_path + "image.png") )

print("------ Done -------")

Perhaps this is happening because, even if Tesseract is correctly installed, you have not installed your language, as was my case. Fortunately this is very easy to fix, and I did not even need to mess with tesseract_cmd.

sudo apt-get install tesseract-ocr -y
sudo apt-get install tesseract-ocr-spa -y
tesseract --list-langs

Note that in the second line we have specified -spa for Spanish.

If installation has been successful, you should get a list of your available languages, like:

List of available languages (3):

I found this at this blog post (Spanish). There is also a post for installation of Spanish language in Windows (not as easy apparently).

Note: since the question uses lang = 'eng', it is likely this is not the answer in that specific case. But the same error may happen in this other situation, which is why I posted the answer here.

Solution for UBUNTU Worked for me:

Installed tesseract in ubuntu by following below link


Later added traindata language to tessdata by following below link

Tesseract running error

There are already many nice answers to this problem but I would like to share a wonderful site that I came across when I couldnt solve the 'TesseractNotFound Error: tesseract is not installed or it's not in your path” Please refer this site: https://www.thetopsites.net/article/50655738.shtml

I realised that I got this error because I installed pytesseract with pip but forget to install the binary. You are probably missing tesseract-ocr from your machine. Check the installation instructions here: https://github.com/tesseract-ocr/tesseract/wiki

On a Mac, you can just install using homebrew:

brew install tesseract

It should run fine after that!

Under Windows 10 OS environment, the following method works for me:

  1. Go to this link and Download tesseract and install it. Windows version is available here: https://github.com/UB-Mannheim/tesseract/wiki

  2. Find script file pytesseract.py from C:\Users\User\Anaconda3\Lib\site-packages\pytesseract and open it. Change the following code from tesseract_cmd = 'tesseract' to: tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract.exe' (This is the path where you install Tesseract-OCR so please check where you install it and accordingly update the path)

  3. You may also need to add environment variable C:/Program Files (x86)/Tesseract-OCR/

Hope it works for you!

For Ubuntu 18.04

If you are getting an error like

 tesseract is not installed or it's not in your path


 OSError: [Errno 12] Cannot allocate memory

That might be and issue with the swap memory allocation issue

You can check this answer allocating more swap memory Hope that helps :)


Use the following command to install tesseract

pip install tesseract

# {Windows 10 instructions}
# before you use the script you need to install the dependence
# 1. download the tesseract from the official link:
#   https://github.com/UB-Mannheim/tesseract/wiki
# 2. install the tesseract
#   i chosed this path
#       *replace the user string in the below path with you name of user that you are using in your current machine
#       C:\Users\user\AppData\Local\Tesseract-OCR\
# 3. Install the  pillow for your python version
# * the best way for me is to install is this form(i'am using python3.7 version and in my CMD i run this version of python by     typing py -3.7):

There looks to be an issue with the latest version of the pip module pytesseract=0.3.7. I have downgraded it to pytesseract=0.3.6 and don't see the error.
