Scipy & Ipython Notebook: how to save and load results?

Now I'm using Ipython Notebook. There is part of my program need a long time to get the result, so I want to save the result and load it when next time I use the script. Otherwise I need to repeat the calculation and need a lot time for this.

I'm wondering is there any good practice of saving and load results? which makes it easier to resume the script the next time I need it?

It's easy to save text results, but in scipy, numpy, the result may be quite complex, e.g. matrix, numerical array.

There are several options, such as pickle, which allows you to save almost anything. However, if what you are going to save are numeric numpy arrays/matices, np.save and np.load seem to be more appropiate.

data = # my data np array
np.save('mypath', data)
data = np.load('mypath')
