Load text Files to python weka wrapper -

-

i've installed weka python wrapper on windows 7. , tried running sample code:

import weka.core.jvm jvm jvm.start()  data_dir = "e:/files/fourth/"  weka.core.converters import loader loader = loader("weka.core.converters.textdirectoryloader") datasets = [     data_dir + "file 1",     data_dir + "file 2",     data_dir + "file 3",     data_dir + "file 4",     data_dir + "file 5"      ] data = loader.load_file(datasets) data.delete_last_attribute() print(data)

and received following error:

traceback (most recent call last):  file "c:/python27/weekaa.py", line 16, in <module>   data = loader.load_file(datasets)  file "c:\python27\lib\site-packages\weka\core\converters.py", line 67,  in load_file   self.enforce_type(self.jobject, "weka.core.converters.filesourcedconverter")  file "c:\python27\lib\site-packages\weka\core\classes.py", line 155, in  enforce_type     raise typeerror("object not implement or subclass " + intf_or_class  + "!") typeerror: object not implement or    subclass  weka.core.converters.filesourcedconverter!

i tried solution in previous asked question (in stackoverflow) adding class path weka.jar or python-weka-wrapper didn't work. error doesn't appear when loading .arff file type.

is there solution load text files?

note: each file in dataset has set of text document files(for later clustering)

weka's textdirectoryloader class cannot used python-weka-wrapper version 0.2.2. upcoming release 0.2.3 (or github repository) contain new python wrapper called textdirectoryloader available weka.core.converters module allows use class now. answered on python-weka-wrapper mailing list.

from weka.core.converters import textdirectoryloader text_dir = "/the/directory/you/want/to/load" loader = textdirectoryloader(options=["-dir", text_dir, "-f", "-charset", "utf-8"]) data = loader.load() print(unicode(data))

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
