python - Scipy.loadmat() ---- SystemError: ../Objects/stringobject.c:3899: bad argument to internal function -


i'm trying load .mat file python quite large ( >75mb) , getting following error. can helped?

traceback (most recent call last):   file "prop_keys.py", line 34, in <module>     prop_d = scipy.io.loadmat(prop)   file "/usr/lib/python2.7/dist-packages/scipy/io/matlab/mio.py", line 175, in loadmat     matfile_dict = mr.get_variables(variable_names)   file "/usr/lib/python2.7/dist-packages/scipy/io/matlab/mio5.py", line 272, in get_variables     hdr, next_position = self.read_var_header()   file "/usr/lib/python2.7/dist-packages/scipy/io/matlab/mio5.py", line 224, in read_var_header     stream = bytesio(dcor.decompress(data)) systemerror: ../objects/stringobject.c:3899: bad argument internal function

as noted here: http://projects.scipy.org/scipy/ticket/1894

the file contains compressed data blows 1.1gb when uncompressed. error message symptom of machine not having enough free memory store data. in addition this, latter part of file seems corrupted , cannot correctly loaded matlab either.

(scipy's mat-file loading routines require 2x memory if data compressed; however, fixed in scipy 0.13.0.)

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
