问题 I've got the authentication working with flask-login, but it seems like no matter what I use for the cookie duration in flask, the session is still authenticated. Am I setting the config variables properly for flask-login? I've tried app.REMEMBER_COOKIE_DURATION = datetime.timedelta(seconds=30) app.config["REMEMBER_COOKIE_DURATION"] = datetime.timedelta(seconds=30) Even if I close the browser, wait a while, and hit a url that should be protected, I can still access it. Is this related to this

问题 I am lost in the scikit learn 0.18 user manual (http://scikit-learn.org/dev/modules/generated/sklearn.neural_network.MLPClassifier.html#sklearn.neural_network.MLPClassifier): hidden_layer_sizes : tuple, length = n_layers - 2, default (100,) The ith element represents the number of neurons in the ith hidden layer. If I am looking for only 1 hidden layer and 7 hidden units in my model, should I put like this? Thanks! hidden_layer_sizes=(7, 1) 回答1: hidden_layer_sizes=(7,) if you want only 1

问题 I'm trying to use Windows Task Scheduler to run a script in python and write a csv file. I've always used Anaconda, so I don't understand how Python's command line works. If I run this on Spyder, import pandas as pd import datetime now_is = pd.DataFrame(['Now is '+ str(datetime.datetime.now())]) now_is.to_csv('C:/Users/camila/now_is.csv') it works perfectly. But Task Scheduler executes this .py using the command terminal, where this code won't work. I guess I need to install pandas again, but

问题 Using re.sub in Python 2.7, the following example uses a simple backreference: re.sub('-{1,2}', r'\g<0> ', 'pro----gram-files') It outputs the following string as expected: 'pro-- -- gram- files' I would expect the following example to be identical, but it is not: def dashrepl(matchobj): return r'\g<0> ' re.sub('-{1,2}', dashrepl, 'pro----gram-files') This gives the following unexpected output: 'pro\\g<0> \\g<0> gram\\g<0> files' Why do the two examples give different output? Did I miss
