问题 I am working on Yolo3-4-PY to implement it with tkinter. I've looked up everywhere but not able to resolve the issue. When I run the program the canvas is displayed but when I click on Start Video( btton ) I get the following error: Loading weights from weights/yolov3.weights...Done! /usr/local/lib/python3.5/dist-packages/PIL/ImageTk.py:119: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison if mode not in ["1", "L",

问题 I'm having some issues with my program, basically what I'm trying to do is Stenography, insert an image into another image and then extract the secret image. My program is able to insert just fine, but extracting it I get this error. It was working fine the other day, I was able to read and write perfectly. I am also using the same BMP images as the other day as well. Anyone know the issue? I didn't change any of the code from it's working state, I even uploaded to github to make sure that

问题 All sorta new to using Microsoft Azure and needed help deploying a Django App to it. When I push the code from my local repo to Azure it gives me this log. I noticed it says : The headers or library files could not be found for zlib, a required dependency when compiling Pillow from source. Please see the install instructions at https://pillow.readthedocs.io/en/latest/installation.html I did more reading and learnt that Azure cannot install PIL or Pillow from the environment and hence needs to

问题 When I try to install Pillow (as a wheel file) C:\Python27\Scripts>pip install C:\Users\karth\Desktop\Pillow-3.4.2-cp36-cp36m-win_amd64.whl I get the following error. Pillow-3.4.2-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform. 回答1: You have a wheel file which is expecting a different Python version. The cp36, indicates CPython 3.6, i.e. Python 3.6. You are running Python 2.7. Either update your Python version, or more suitably, get a wheel file of the correct version from

问题 I've been trying to generate the equivalent of matplotlib's matshow function as a PIL image. During this process, I realized that the colors that I'm generating by applying the colormaps are always slightly redder than they are in the mathshow version. Here is a quick test code that I wrote up to test and verify the scenario: import matplotlib import matplotlib.pyplot as plt import numpy as np from PIL import Image data = np.ones((5,5))*0.5 cmap = matplotlib.cm.jet #generate PIL image m =

问题 I am using django image and creating a custom processor. I want to find out the size in KB (or bytes) but unable to do so. The size attribute give the dimensions and not the size of the file. I am a newbie so have only been able to find attr of PIL to get more information about the image but none of the them actually give the file size in bytes. I have creating this processor for a ModelForm. Can you please help with this? I am adding the code written so far. It is more of a test code; import

问题 I am trying to compare two photos in python that are similar but not picture perfect. I am using the Pillow library (my code is below). The code checks to see how similar two photos are and return a percentage. Update: My code is not returning certain images that to the eye would be similar (example below). Could someone explain why? Check image similarity def imageSimilarity(self,i1,i2): pairs = zip(i1.getdata(), i2.getdata()) if len(i1.getbands()) == 1: # for gray-scale jpegs dif = sum(abs

问题 An 256*64 pixel OLED display connected to Raspberry Pi (Zero W) has 4 bit greyscale pixel data packed into a byte (i.e. two pixels per byte), so 8192 bytes in total. E.g. the bytes 0a 0b 0c 0d (only lower nibble has data) become ab cd Converting these bytes either obtained from a Pillow (PIL) Image or a cairo ImageSurface takes up to 0.9 s when naively iterating the pixel data, depending on color depth. Combining every two bytes from a Pillow "L" (monochrome 8 bit) Image: imd = im.tobytes()

问题 I am running a linux box with ubuntu 14, it runs an apache2 server that hosts a Django application. This application imports PIL from the installed Pillow library. It was all working fine when I was on Python 3.5, however after upgrading to Python 3.6 and reinstalling Pillow in the Virtualenv, I get an error when the webserver tries importing PIL. When I run the Python interpreter it all imports fine as it uses the py script directly however as the webserver is using the installed and
