This changes a theme for a normal jupyter notebook. But no affect on the jupyter lab appearance. I also tried to install a theme using jupyter-theme, but alas, no changes in jupyter lab appearance. Can someone point me to the how-to guide? 回答1: UPDATE 02/03/2018 Now this option is already built in in the settings menu!

But I still can't figure out how to avoid applying them on per element basis. For example, if I have a behavior as such: <Rectangle> <i:Interaction.Behaviors> <il:MouseDragElementBehavior/> </i:Interaction.Behaviors> </Rectangle> and I have a few draggable rectangles in my Window, each of them has to have the above markup to be draggable. What I would like to do is to be able to write something like this: <Style x:Key=

Really we just want the push function, and b.push.apply(a, b) accomplishes exactly the same thing -- the first argument of apply supplies the this for the applied function. I thought it might make more sense to directly use the methods of the Array object: Array.push.apply(a, b) . But this doesn't work! I'm curious why not, and if there's a better way to accomplish my goal. (Applying the push

However, it only appears in Debug mode. 回答1: It appears that the issue is related to ClickOnce. Navigate to the project, right click on it and click on properties. Go to the Publish tab and click on

I tried hr.means <- aggregate(X2, format(X2["timestamp"],"%Y-%m-%d %H")) and got always error with trim argument. Is there an easier function similar to apply.daily? What if I want to aggregate the mean of 5 minutes. Data are values per minute: "timestamp", value "2012-04-09 05:03:00",2 "2012-04-09 05:04:00",4 "2012-04-09 05:05:00",5 "2012-04-09 05:06:00",0 "2012-04-09 05:07:00",0 "2012-04-09 05:08:00",3 "2012-04-09 05:09:00

My function is as simple as possible: def my_func ( row ): print row And my apply code is the following: df [[ 'A' , 'B' ]]. apply ( lambda x : my_func ( x ) if ( pd . notnull ( x [ 0 ])) else x , axis = 1 ) It works perfectly. If I want to check column 'B' for NULL values the pd.notnull() works perfectly as well. But

I know this is a very simple task, but I have never been across any function that does this. Thanks, 回答1: The problem here is that your column variance is equal to zero. You can check which column of a data frame is constant this way, for example : df <- data.frame(x=1:5,
