How do you make NLTK draw() trees that are inline in iPython/Jupyter -

-

for matplotlib plots in ipython/jupyter can make notebook plot plots inline 

%matplotlib inline

how can 1 same nltk draw() trees? here documentation http://www.nltk.org/api/nltk.draw.html

based on this answer:

import os ipython.display import image, display nltk.draw import treewidget nltk.draw.util import canvasframe  def jupyter_draw_nltk_tree(tree):     cf = canvasframe()     tc = treewidget(cf.canvas(), tree)     tc['node_font'] = 'arial 13 bold'     tc['leaf_font'] = 'arial 14'     tc['node_color'] = '#005990'     tc['leaf_color'] = '#3f8f57'     tc['line_color'] = '#175252'     cf.add_widget(tc, 10, 10)     cf.print_to_file('tmp_tree_output.ps')     cf.destroy()     os.system('convert tmp_tree_output.ps tmp_tree_output.png')     display(image(filename='tmp_tree_output.png'))     os.system('rm tmp_tree_output.ps tmp_tree_output.png')

little slow, job. if you're doing remotely, don't forget run ssh session -x key (like ssh -x user@server.com) tk initialize (no display name , no $display environment variable-kind of error)

upd: seems last versions of jupyter , nltk work nicely together, can ipython.core.display.display(tree) nice-looking tree-render embedded output.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
