Hi, I have a Macbook with OS 10.6.6 with a fink installation and am still using python 2.5.5. I installed matplotlib 1.0.0. The backend is Tkagg.
Trying to start a plot causes a crash of the python shell as follows: bash-3.2$ python2.5 Python 2.5.5 (r255:77872, Mar 27 2011, 11:08:21) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import pylab >>> get_backend() Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'get_backend' is not defined >>> pylab.get_backend() 'TkAgg' >>> ion() Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'ion' is not defined >>> pylab.ion() >>> fig1 = pylab.figure(1) Exception in Tkinter callback Traceback (most recent call last): File "/sw/lib/python2.5/lib-tk/Tkinter.py", line 1414, in __call__ return self.func(*args) File "/sw/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 248, in resize self.show() File "/sw/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 252, in draw tkagg.blit(self._tkphoto, self.renderer._renderer, colormode=2) File "/sw/lib/python2.5/site-packages/matplotlib/backends/tkagg.py", line 19, in blit tk.call("PyAggImagePhoto", photoimage, id(aggimage), colormode, id(bbox_array)) TclError >>> alloc: invalid block: 0x102092f50: 0 35 Abort trap bash-3.2$ So opening a figure causes the crash. Any suggestions on how to fix this? Did anyone else have this problem? Could it be that there is an incompatibility with gcc ? the Fink installation has gcc 4.5. Any suggestions will be appreciated. At the moment moving to python 2.6 or 2.7 seems a good idea, but it will involve a lot of testing of my code. ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
