Can't run wrapper from Spyder

[rg]

Hi I have added the paths for the wrapper and javabridge in the PYTHONPATH for Spyder. But I still get this error:

>import weka.core.jvm as jvm

Traceback (most recent call last):

  File "<ipython-input-1-3ffc2a186fc1>", line 1, in <module>

    import weka.core.jvm as jvm

ImportError: No module named weka.core.jvm

Could you please help me out.

Did you install python-weka-wrapper using pip?

If not and you're just using the source downloaded from pypi or
github, then you don't need to add the javabridge and
python-weka-wrapper paths to the PYTHONPATH manager. Instead, just set
the working directory to the python-weka-wrapper's "python" directory
(see attached screenshot).

Cheers, Peter

Javabridge is not a pure Python package, you need to install it via pip:

pip install javabridge

Install one of the pre-compiled modules of javabridge:
