阅读更多关于 in NetworkX cannot save a graph as jpg or png file

问题 I have a graph in NetworkX containing some info. After the graph is shown, I want to save it as jpg or png file. I used the matplotlib function savefig but when the image is saved, it does not contain anything. It is just a white image. Here is a sample code I wrote: import networkx as nx import matplotlib.pyplot as plt fig = plt.figure(figsize=(12,12)) ax = plt.subplot(111) ax.set_title('Graph - Shapes', fontsize=10) G = nx.DiGraph() G.add_node('shape1', level=1) G.add_node('shape2', level=2

Avoid recursive save() when using celery to update Django model fields

阅读更多关于 Avoid recursive save() when using celery to update Django model fields

问题 I'm overriding a model's save() method to call an asynchronous task with Celery. That task also saves the model, and so I end up with a recursive situation where the Celery task gets called repeatedly. Here's the code: Model's save method: def save(self, *args, **kwargs): super(Route, self).save(*args, **kwargs) from .tasks import get_elevation_data get_elevation_data.delay(self) get_elevation_data task: from celery.decorators import task @task() def get_elevation_data(route): ... route

How to bookmark a webpage in an Android application?

阅读更多关于 How to bookmark a webpage in an Android application?

I am developing a Newspaper like application. I'm wondering how to save webpages with the click of a button and display it at a later point in time. I googled for this in vain. If anyone knows how to do this and can provide some useful links, it would be greatly appreciated. Perhaps you can just save the url in a database together with the favicon or try to get a screenshot from the site to use as icon? You could probably convert the Webview to a Drawable/Bitmap without too much problems. Here's two database/sql tutorials for Android: http://www.screaming-penguin.com/node/7742 http://developer

Python - How can I make this un-pickleable object pickleable?

阅读更多关于 Python - How can I make this un-pickleable object pickleable?

So, I have an object that has quite a bit of non-pickleable things in it (pygame events, orderedDicts, clock, etc.) and I need to save it to disk. Thing is, if I can just get this thing to store a string that has the progress (a single integer is all I need), then I can pass it to the object's init and it will rebuild all of those things. Unfortunately, a framework I am using (Renpy) will pickle the object and attempt to load it, despite the fact that I could save it as a single integer, and I can't change that. So, what I'm asking is, how can I override methods so that whenever pickle tries
