The link you are using to wget is all wrong. You are actually sending a GET request to the html file instead of the image.
Here's the actual image link for you :)

I was trying to convert an image to text, I execute this code on Google Colab, I think, I have a problem with the path of a file, maybe, so, please help to get a solution to this code. How can I get a solution?
from PIL import Image
import pytesseract
# Open the temporary file using PIL
image = Image.open("image.png")
# Use the Tesseract OCR engine to extract the text
text = pytesseract.image_to_string(image, lang = 'eng', config='--psm 11')
# Print the extracted text
print(text)

I got this error when I execute. How can I get a solution to image = Image.open("image.png")?
I wrote a small Python script which takes all .jpeg img-files from a given "./Input" folder, creates a thumbnail from these images and saves them in a "./Output" file. It works perfectly fine when executed in an IDEA (In my case PyCharm), but when I created the executable with pyinstaller and tried to execute it, the following error appeared:
Traceback (most recent call last):
File "image_resizer.py", line 3, in <module>
ModuleNotFoundError: No module named 'PIL'

Here is my code:
import shutil
from PIL import Image
import glob, os
import time
output_directory = "./Output"
def photo_picker():
pictures = []
try:
for filename in glob.iglob("./Input/*.jpg"):
pictures.append(filename)
except FileNotFoundError:
print("could not execute")
return pictures
def create_output_folder():
if os.path.exists(output_directory):
shutil.rmtree(output_directory)
try:
os.mkdir(path=output_directory, mode=777)
except FileExistsError:
print("Could not execute")
def crop_image(img, new_name):
size = (2000, 2000)
with Image.open(img) as im:
im.thumbnail(size)
print(im.info)
img_name = f"{new_name}"
im.save(output_directory + "/" + img_name, "JPEG")
def main():
photos = photo_picker()
create_output_folder()
time.sleep(2)
for f in photos:
img_name_splitted = f.split("/")
img_name = img_name_splitted[len(img_name_splitted) - 1]
print(img_name)
crop_image(f, img_name)
return 0

I installed the module Pillow, uninstalled it ,tried to install PIL (which didn't work). But as I mentioned before, when executing it in an IDEA it works.
I'm working on GCP cloud functions and intend to write a functions which combines two images. But I', getting the following error when I invoke the function:
Traceback (most recent call last): File

PIL.UnidentifiedImageError: cannot identify image file '/tmp/logo.jpg'
I have ran this function on my local machine and it works as expected but when I deploy it on GCP, it gives this error and crashes. Here's my function:
from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw
def generateIntroImage(stdName, stdPicture, logo, year, typeFace):
images = [Image.open(x) for x in [stdPicture, logo]]
widths, heights = zip(*(i.size for i in images))
total_width = sum(widths)
max_height = max(heights)
new_im = Image.new('RGB', (total_width, max_height))
x_offset = 0
for im in images:
new_im.paste(im, (x_offset,0))
x_offset += im.size[0]
font= ImageFont.truetype(typeFace, 70)
draw= ImageDraw.Draw(new_im)
draw.text((0, 0), stdName+"'s " +year+" Year Book", (0,0,0),font= font)
fileName= "/tmp/test.jpg"
new_im.save(fileName)
return fileName
These images are .jpg and .png files. Any idea what could be wrong?
Happened to me on Google Colab as well, apparently updating PIL version fixed the problem for me.
PIL throws error because it cannot identify the image format. Most probably the reason is that the image is corrupted and hence cannot be read (or "identified") by pillow's Image.open(). For example if you try opening the image in an IPython prompt, it would fail as well.
In [2]: from PIL import Image
In [3]: Image.open("176678612.jpg")

raise UnidentifiedImageError(

So, the fix is to delete the image, or replace it with an uncorrupted version.
you need to provide a downloadable link to the image. What worked for me was click on the download image and the copy that URL.
import tifffile
f = 'some.tif'

Try this code out, as recommended by #cgohlke:

img = tiff.imread('/content/gdrive/My Drive/My Driver/imageToDriveExample.tif')

So I have a Python application that accesses the built-in webcam on a laptop and takes a picture. But I'm having difficulty specifying the storage location for the picture (in this case on the desktop). The code I have so far is:
import cv2
import time
import getpass
import os
getUser = getpass.getuser()
save = 'C:/Users/' + getUser + "/Desktop"
camera_port = 0
camera = cv2.VideoCapture(camera_port)
time.sleep(0.1)
return_value, image = camera.read()
os.path.join(cv2.imwrite(save, "user.png", image))
del camera
But when I run it I get the following error:
Traceback (most recent call last):
File "C:/Users/RedCode/PycharmProjects/MyApps/WebcamPic.py", line 13, in <module>
os.path.join(cv2.imwrite(save, "user.png", image))
TypeError: img is not a numpy array, neither a scalar
How can I specify where to store the image when it is taken?
This line here is where you have a problem.
os.path.join(cv2.imwrite(save, "user.png", image))
You want to do this
cv2.imwrite(os.path.join(save, "user.png"), image)
imwrite expects two arguments the file name and the image to be saved.
The call to os.path.join is building your saved file path.
