Pytesseract：“TesseractNotFound 错误：tesseract 未安装或不在您的路径中”，我该如何解决？

Question

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')

print(text)

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.

Answer 1

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'

Answer 2

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

Answer 3

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. ie 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.

Answer 4

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

Answer 5

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'

Answer 6

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

Answer 7

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

brew install tesseract

Answer 8

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...

Answer 9

在 Windows 64 位上，只需将以下内容添加到 PATH 环境变量： "C:\\Program Files\\Tesseract-OCR" ，它就会工作。

Answer 10

我可以通过使用 pytesseract.py 文件中的 bin/tesseract 路径更新 tesseract_cmd 变量来解决它

Answer 11

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

Answer 12

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 
following:
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract- 
OCR/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
    #os.remove(temp)

    return result


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

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

Answer 13

You would be needing to install tesseract.

https://github.com/tesseract-ocr/tesseract/wiki

Check out the above documentation on the installation.

Answer 14

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' 

2. In 64 bit system, add this line instead.

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

Answer 15

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):
eng
osd
spa

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.

Answer 16

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" 

Answer 17

仅通过使用conda安装tesseract就对我conda 。

conda install -c conda-forge tesseract

Answer 18

For Linux Distribution (Ubuntu)

try

sudo apt install tesseract-ocr
sudo apt install libtesseract-dev

Answer 19

使用以下命令安装tesseract

pip install tesseract

For Ubuntu 18.04

If you are getting an error like

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

 and 

 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 :)

Answer 22

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!

Solution for UBUNTU Worked for me:

Installed tesseract in ubuntu by following below link

https://medium.com/quantrium-tech/installing-tesseract-4-on-ubuntu-18-04-b6fcd0cbd78f

Later added traindata language to tessdata by following below link

Answer 24

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.

Answer 25

For Windows in simple steps:

1. Download Windows version from https://github.com/UB-Mannheim/tesseract/wiki

2. Install

3. Write following in your .py file (check installed location)

    pytesseract.pytesseract.tesseract_cmd = r"C:\\Program Files\\Tesseract-OCR\\tesseract.exe" img_text = pytesseract.image_to_string(Image.open(filename))

Answer 26

for me it worked by putting single quote

pytesseract.pytesseract.tesseract_cmd =r'C:/Program Files/Tesseract-OCR/tesseract.exe'

actually putting inside double quotes was automatically inserting unwanted chracter

Answer 27

The above tips did not help me fix the problem, because the error specified in the section occurred when installing pytesseract (pycharm, python 2.7). The oddity was also that tesseract worked from the command line, so the installation was done correctly.

I was able to fix this problem by following these steps:

1. download pytesseract.py from the vault https://github.com/madmaze/pytesseract
2. remove all syntax errors related to the difference in the interpreters (2.7 and 3.*), including the try catch methods
3. import the edited script into your program as a self-written one and configure the tesseract_cmd variable according to the recommendations in the repository.

Subsequently, the image-to-text translation function worked in python 2.7

Answer 28

Anaconda Installation:

Works on Mac, Linux, and Windows

conda-forge/packages/tesseract 4.1.1

Step 1:

conda install -c conda-forge tesseract

Step 2: Find Tesseract PATH if you haven't already

for r,s,f in os.walk("/"):
    for i in f:
        if "tesseract" in i:
            print(os.path.join(r,i))

For example, my Tesseract PATH is /anaconda/bin/tesseract

Step 3: Add tesseract to PATH

pytesseract.pytesseract.tesseract_cmd = r'/anaconda/bin/tesseract'

Answer 29

I aleady tried this one on my raspberry pi. I just changed the path from this:

C:/Program Files/Tesseract-OCR/tesseract.exe'

(Since, it is for windows) To this:

/usr/local/lib/python3.7/dist-packages

Since, it is the path I see whenever I try to run this command:

pip3 show pytesseract

For better clarity here's the message. Command line here

Answer 30

I am also facing an same error while installing tesseract.

Based my recent problem solving i am following thsese below steps

1. Install tesseract using windows installer available in the gievn link: 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.

After installations, still it is showing error or not installing error you are facing then press windows + R keys and run your file path (C:\\Program Files\\Tesseract-OCR\\tesseract.exe) it wil work for me,

3. pip install pytesseract

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

For windows file path -

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

For linux installations will vary, but linux file path was given below

pytesseract.pytesseract.tesseract_cmd = r'home/user/bin/tesseract'

6. For installing opencv please - refer this question link

Answer 31

!sudo apt install tesseract-ocr 

Answer 32
