matplotlib - How to install wxversion for Python -

-

i'm experimenting "spy" spectral python library, using pycharm, , i've gotten point tells me wxversion not found. how can install wxversion?

i'm new python in general, doing else wrong? here code:

import matplotlib #matplotlib.use('wx')    #replaced editing matplotlibrc spectral import *  img = open_image('92av3c.lan') print img.__class__ print print img print print img.shape pixel = img[50,100] print print pixel.shape band6 = img[:,:,5] print print band6.shape print   arr = img.load()  print arr.__class__ print print arr.info() print print arr.shape  view = imshow(img, (29, 19, 9))

all of spy guide here: http://www.spectralpython.net/user_guide.html

here error:

traceback (most recent call last):   file "/users/pkillam/pycharmprojects/untitled/spy experiments", line 36, in <module>   file "/library/python/2.7/site-packages/spectral/graphics/spypylab.py", line 1238, in imshow     import matplotlib.pyplot plt   file "/system/library/frameworks/python.framework/versions/2.7/extras/lib/python/matplotlib/pyplot.py", line 98, in <module>     _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()   file "/system/library/frameworks/python.framework/versions/2.7/extras/lib/python/matplotlib/backends/__init__.py", line 28, in pylab_setup     globals(),locals(),[backend_name],0)   file "/system/library/frameworks/python.framework/versions/2.7/extras/lib/python/matplotlib/backends/backend_wxagg.py", line 6, in <module>     import backend_wx    # uses wxversion.ensureminimal('2.8')   file "/system/library/frameworks/python.framework/versions/2.7/extras/lib/python/matplotlib/backends/backend_wx.py", line 53, in <module>     raise importerror(missingwxversion) importerror: matplotlib backend_wx , backend_wxagg require wxversion, not found.

also, there other guides/tutorials out there spy?

you can install wxpython on mac downloading www.wxpython.org. please take note of following notice on website:

note: installer not signed apple, default mac tell corrupted , not install it. can around temporarily relaxing security settings in system preferences. in security & privacy section set "allow applications downloaded from" "anywhere."

i have followed directions , had no problem installing wxpython on mac (yosemite) once changed settings.

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
