问题 I'm connected to remote system through ssh, and trying to read frames using OpenCV VideoCapture in Python. The same code succeeds when using Python 2.7 and fails when using Python 3.5: import cv2 cap = cv2.VideoCapture(0) Python2.7: print cap.isOpened() # prints True, further read() calls also return True Python3.5: print (cap.isOpened()) # prints False, and so are cap.open(), and of course cap.read(). What could cause such behavior? Thanks! 回答1: I had exactly the same problem. OpenCV was

问题 Hi I am trying out a simple autoencoder in Python 3.5 using Keras library. The issue I face is - ValueError: Error when checking input: expected input_40 to have 2 dimensions, but got array with shape (32, 256, 256, 3). My dataset is very small (60 RGB images with dimension - 256*256 and one same type of image to validate). I am a bit new to Python. Please help. import matplotlib.pyplot as plt from keras.layers import Input, Dense from keras.models import Model #Declaring the model encoding

问题 I would like to scrape two websites in java for links using PyQt4.QtWebKit to render the pages and then get the desired links. The code works fine with one page or url, but stops (but continues running until force quit) after printing the links of the first website. It seems the scope stays in the event loop of the render class. How can I get the program to change scope and continue with the for loop and rendering the second website? Using exit() in _loadFinished method just quits the program

问题 disclaimer, I've already done a long research to solve that alone but most of the questions I found here concern Python 2.7 or doesn't solve my problem Let's say I've the following (That example comes from BeautifulSoup doc, I'm trying to solve a bigger issue): >>> markup = "<h1>Sacr\xc3\xa9 bleu!</h1>" >>> print(markup) 'Sacré bleu!' For me, markup should be assigned to a bytes, so I could do: >>> markup = b"<h1>Sacr\xc3\xa9 bleu!</h1>" >>> print(str(markup, 'utf-8')) <h1>Sacré bleu!</h1>

问题 In NetworkX 'm trying to accomplish the following: within one graph create 'mother-nodes' and 'children-nodes', where children-nodes have only 1 attribute, and mother-nodes have several (4). create edges between mother-nodes and children-nodes if at least one attribute (key-value pair) is the same, create an edge only between a mother-node and children-node: even if two mother-nodes have one of 4 overlapping attributes, there should not be an edge between the two So far I have the first part
