ipython-notebook

I am using ipython, with a code that looks like this: image = zeros(MAX_X, MAX_Y) # do something complicated to get the pixel values... # pixel values are now in [0, 1]. imshow(image) However, the resulting image always has the same resolution, around (250x250). I thought that the image's dimensions would be (MAX_X x MAX_Y), but that is seemingly not the case. How can I make ipython give me an image with a greater resolution? The height and width of the displayed image on the screen is controlled by the figure size and the axes size. figure(figsize = (10,10)) # creates a figure 10 inches by 10

When I call pyplot.title('some string') it throws the exception, 'str' object is not callable' . I copied the following from the matplotlib online documentation: mu, sigma = 100, 15 x = mu + sigma * np.random.randn(10000) # the histogram of the data n, bins, patches = plt.hist(x, 50, normed=1, facecolor='g', alpha=0.75) plt.xlabel('Smarts') plt.ylabel('Probability') plt.title('Histogram of IQ') plt.text(60, .025, r'$\mu=100,\ \sigma=15$') plt.axis([40, 160, 0, 0.03]) plt.grid(True) plt.show() and get TypeError Traceback (most recent call last) <ipython-input-158-40fe7a831b06> in <module>() 8

When I launch IPython Notebook I can navigate to it and enter code. However, nothing is ever echo'd back to the IPython Notebook interface. I know the server is getting the queries (from --debug output ) and responding to them it's just never giving me output in my IPython Notebook window. I am running Python 2.6.6 and Windows 7 I am at a loss currently on how to get this notebook thing to work. Here is a screencast of me trying (unsuccessfully) to get output: http://screencast.com/t/TwJ2ZmGnT Even if you don't know what's wrong, any pointers on how to further debug my problems :( So far I

I have a notebook which I intend to use as a library for other notebooks. It has some functions that can ready certain types of files etc. How can I include that notebook in a new notebook that should be able to use the functions in the library notebook? googling for notebook import hook yield some example s. This is still experimental, but you are welcomed to improved it. I would suggest also using the --script flag that save an importable .py file every time you save the notebook. You can just enter %run 'NotebookA.ipynb' in Notebook B and you should be good to go! With import_ipynb library

I tried to open ipython in terminal with ipython notebook and it will not open ipython notebook. It gives the following error: | ~/documents/ud120-projects/datasets_questions @ HJ (JiaHui) | => ipython notebook [TerminalIPythonApp] WARNING | Subcommand `ipython notebook` is deprecated and will be removed in future versions.
