I am using a Mac and installed tesseract successfully.
However, when am writing the code to read a jpeg or png file it gives me an error:
TypeError: Unsupported image object
The code snippet is as follows:
import cv2
import pytesseract
img = cv2.imread('image.png')
text = pytesseract.image_to_string(img)
print(text)
Please suggest. Thanks in advance.
Add the statement:
pytesseract.pytesseract.tesseract_cmd = '/usr/local/Cellar/tesseract/4.1.1/bin/tesseract'
to your code before using pytesseract. To know where pytesseract is installed in your mac you can use the command as shown below if tesseract is installed using brew.
brew list tesseract
I have installed the PILLOW module in Windows 8.1 for Python 3 using the below command.
pip install pillow
The installation was a success.
Unfortunately when I tried to import the image sub-module within it using the below statement I got an import error.
from PIL import image
Error: ImportError: cannot import name 'image' from 'PIL' (C:\Program Files\Python38\lib\site-packages\PIL_init_.py)
Although the below statement is giving me an error for the 'PIL' .
image = PIL.Image.open("Capture Image.PNG")
Error: Undefined variable: ' PIL'Python(undefined-variable)
I have tried similar posts listed below, but they didn't help me to solve the issue.
Pip install Pillow: "no module named Pillow?"
Pillow installed, but getting "no module named pillow" when importing
Python pillow module not importing properly
Could you please someone explain what I'm missing here?

#dragon2fly Many thanks for solving the issue. Please refer the below snippet for the complete source code.
from PIL import Image
image = Image.open("Capture_image.png")
print(image.size)
When I try:
>>> from skimage import io
I get at the end the following:
from ..color import rgb2gray
ImportError: cannot import name 'rgb2gray' from 'skimage.color' (C:\Users\user\A
ppData\Local\Programs\Python\Python37-32\lib\site-packages\skimage\color\__init_
_.py)
Although I have installed the packages: matplotlib, scipy, pillow, numpy and six
How can I fix it? Any help would be appreciated
In case you run into this error from inside a Jupyter Notebook, try restarting the kernel as suggested in this GitHub issue.
That solved the problem for me.
It looks like you haven't installed scikit-image package.
Try this on terminal:
pip install -U scikit-image
And then try importing like this:
from skimage import io
from skimage.color import rgb2gray
If you still got the error or you have installed the package previously,
try reinstalling the package first.
If it still don't resolve your issue, then try updating the following packages:
matplotlib, scipy, pil, numpy and six
However, try not to import all of the subpackages to improve loading time. You can however try something like:
from skimage import color
...
gray_img = color.rgb2gray(img)
If you still got errors, make sure that you are using the correct python kernel and dependent modules are updated and installed.
If that did not help either, then try Anaconda, it come with many pre-installed packages.
Leave a comment if you still have a problem :)
three ways to convert RGB2Gray:
opencv:
import cv2
img=cv2.imread("file.jpg",0) [enter link description here][1]
or you can do this:
img=cv2.imread("file.jpg")
gray=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
cv2.COLOR_BGR2GRAY beacause it reads BGR mode.
another methods you can look this link:

It happened to me once when I import skimage using env conda on Jupyter. I installed by pip or conda in env, that error happened. However, after restart the Jupyter, it worked.
I am using tesseract to extract text out of images.
I use the pytesseract package.
When I run the image_to_string() function I am getting the following error:
TessaractError : (1, '')
What may be the reason for this?
This is my code:
import pytesseract as pyt
text = pyt.image_to_string(Image.open("Figure_3.png"))
print(text)
Thanks for your help.
Previously ROS was installed in my system which requires opencv for its implementation and now I am using anaconda in which I need to use the opencv library once again. While writing python code import cv2 throws an error module not found.
Is there any way to use that opencv library which ROS installed in anaconda
Although I installed opencv once again using conda.
$conda install -c conda-forge opencv
however opencv-3.3 was installed using above command. Now my python code is showing different import error as shown below:
ImportError Traceback (most recent call last)
<ipython-input-9-6b49ad4d4ca5> in <module>()
1 from random import shuffle
2 import glob
----> 3 import cv2
4 shuffle_data = True # shuffle the addresses before saving
5 hdf5_path = 'dataset.hdf5' # address to where you want to save the hdf5 file
ImportError: /home/kamal/ros_catkin_ws/install_isolated/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type
How can I particularly specify which opencv library to use. What env variables I need to change.
Any help will be appreciated.
uncommenting the line source /home/user/ros_catkin_ws/install_isolated/share/setup.bash in the .bashrc file dosen't help. You also need to remove the extrasys.path added by the ROS environment.
In a python console
import sys
print (sys.path)
you will see multiple paths related to ROS
then remove the unwanted part of the path by
sys.path.remove('unwanted_path')
This will solve the problem but now ROS will not work. To make it work you need to append the removed path again.
If someone has a better approach please answer.
