问题 I have some code like this: class Person(object): def drive(self, f, t): raise NotImplementedError class John(Person): def drive(self, f, t): print "John drove from %s to %s" % (f,t) class Kyle(Person): def drive(self, f, t): print "Kyle drove from %s to %s" % (f,t) class RandomPerson(Person): # instansiate either John or Kyle, and inherit it. pass class Vehicle(object): pass class Driver(Person, Vehicle): def __init__(self): # instantiate and inherit a RandomPerson somehow pass d1 = Driver()

问题 I'm trying to do a simple Instagram python bot in order to upload images in my Instagram profile. I've already tried the most common libraries (InstagramAPI, instapy, insta-cly). While I was searching I found out that Instagram has changed something making those libraries useless. Is there any library I can use? I know thatI can use Selenium in order to make it go but I'm wondering if there is any shortcut. Trank you! 回答1: try this library: instabot https://pypi.org/project/instabot/ example

问题 There are several tutorials on the web documenting how to cross-compile or cross-build Python for various embedded systems using some basic hacking and patching, like so: http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html This worked well for me in the past, when I was using Python 2.7.2. In Python 2.7.4, some cross-compile functionality was finally included in the upstream build process, documented here: http://bugs.python.org/issue17086 https://mail.python.org

问题 I'm loading dummy data into a neural network, but I'm receiving an error I can't seem to debug: Here is my data, visualized: df: Label Mar 0 | [[.332, .326], [.058, .138]] 0 | [[.234, .246], [.234, .395]] 1 | [[.084, .23], [.745, .923]], I'm trying to use the 'Mar' column to predict the 'Label' column (I know this data makes no sense, its just similar to my real data). Here is my neural network code: model = Sequential() model.add(Dense(3, input_dim=(1), activation='relu')) model.add(Dense(1,

问题 If I have a list of images represented by 3D ndarray such as [[x,y,color],...] , what operations can I use to output an image with values that are median of all values? I am using a for loop and find it too slow. 回答1: You said your images in color, formatted as a list of 3d ndarrays . Let's say there are n images: imgs = [img_1, ..., img_n] Where imgs is a list and each img_i is a an ndarray with shape (nrows, ncols, 3) . Convert the list to a 4d ndarray, then take the median over the
