Turns out you need to store the links you want to navigate to in advance. This is what ended up working for me (found this thread to be helpful): driver.get(<some url>) elements = driver.find_elements_by_xpath(“//h2/a”) links = [] for i in range(len(elements)): links.append(elements[i].get_attribute(‘href’)) for link in links: print ‘navigating to: ‘ + link driver.get(link) # do … Read more
Left anti join is what you’re looking for: df1.join(df2, [“userid”, “group”], “leftanti”) but the same thing can be done with left outer join: (df1 .join(df2, [“userid”, “group”], “leftouter”) .where(df2[“pick”].isNull()) .drop(df2[“pick”]))
It is my solution for the same problem Install TDM GCC x64. Install Anaconda x64. Open the Anaconda prompt Run conda update conda Run conda update –all Run conda install mingw libpython Install the latest version of Theano, pip install git+git://github.com/Theano/Theano.git Run pip install git+git://github.com/fchollet/keras.git
Graphviz does a good job drawing parallel edges. You can use that with NetworkX by writing a dot file and then processing with Graphviz (e.g. neato layout below). You’ll need pydot or pygraphviz in addition to NetworkX In [1]: import networkx as nx In [2]: G=nx.MultiGraph() In [3]: G.add_edge(1,2) In [4]: G.add_edge(1,2) In [5]: nx.write_dot(G,’multi.dot’) … Read more
To use multiple databases you have to tell Django about the database server you will be using, but adding them in the settings.py. Multiple databases ‘default’: { ‘NAME’: ‘app_data’, ‘ENGINE’: ‘django.db.backends.postgresql’, ‘USER’: ‘postgres_user’, ‘PASSWORD’: ‘s3krit’ }, ‘users’: { ‘NAME’: ‘user_data’, ‘ENGINE’: ‘django.db.backends.mysql’, ‘USER’: ‘mysql_user’, ‘PASSWORD’: ‘priv4te’ } } The migrate management command operates on one … Read more
Ok, so the easiest method to create several plots is this: import matplotlib.pyplot as plt x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]] y=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]] for i in range(len(x)): plt.figure() plt.plot(x[i],y[i]) # Show/save figure as desired. plt.show() # Can show all four figures at once by calling plt.show() here, outside the loop. #plt.show() Note that you need to create a figure every time … Read more
The only solution I could find is reinstalling pip. Run these commands on your terminal wget https://bootstrap.pypa.io/get-pip.py sudo -H python get-pip.py –prefix=/usr/local/ However, this works only for pip, not pip3!
zip computes all the list at once, izip computes the elements only when requested. One important difference is that ‘zip’ returns an actual list, ‘izip’ returns an ‘izip object’, which is not a list and does not support list-specific features (such as indexing): >>> l1 = [1, 2, 3, 4, 5, 6] >>> l2 = … Read more
