TypeError: __init__() got an unexpected keyword argument 'model_str'

[tiny-tinker]

After successfully building from source, I'm running the demo, but ran into this error:

pi@raspberrypi:~/Downloads/snowboy/examples/Python $ python demo.py ./resources/snowboy.umdl 
Traceback (most recent call last):
  File "demo.py", line 27, in <module>
    detector = snowboydecoder.HotwordDetector(model, sensitivity=0.5)
  File "/home/pi/Downloads/snowboy/examples/Python/snowboydecoder.py", line 91, in __init__
    resource_filename=resource, model_str=model_str)
TypeError: __init__() got an unexpected keyword argument 'model_str'

Lines 90s in snowboydecoder.py:

        self.detector = snowboydetect.SnowboyDetect(
            resource_filename=resource, model_str=model_str)        # 91
        self.detector.SetAudioGain(audio_gain)
        self.num_hotwords = self.detector.NumHotwords()

But looking at snowboydetect.py, the constructor takes a pointer, so I'm not sure what it is complaining about. My python skills aren't great.

class SnowboyDetect(_object):
    __swig_setmethods__ = {}
    __setattr__ = lambda self, name, value: _swig_setattr(self, SnowboyDetect, name, value)
    __swig_getmethods__ = {}
    __getattr__ = lambda self, name: _swig_getattr(self, SnowboyDetect, name)
    __repr__ = _swig_repr
    def __init__(self, *args): 
        this = _snowboydetect.new_SnowboyDetect(*args)
        try: self.this.append(this)
        except: self.this = this

Could you try the swig installation commands I pasted here? I suspect it's an issue with swig.

Closing this since the issue was resolved through #17

I also had the Error:
TypeError: init() got an unexpected keyword argument 'model_str'

My Setup:

• Hardware: Raspberry Model B - Generation 1
• OS: Raspbian Jessie

I fixed it running a modified version of the #17 (comment) scipt:

#!/bin/bash

# SWIG is a tool to compile c++ code into Python.

if [ ! -e swig-3.0.7.tar.gz ]; then
  wget -T 10 -t 3 \

tar -xovzf swig-3.0.7.tar.gz || exit 1

./configure --with-pic
make
sudo make install

cd ..

I also installed the needed programs/libs:
https://github.com/Kitt-AI/snowboy#ubunturaspberry-pi
and compiled snowboy myself (the pre-compiled/provided version had the above error)
https://github.com/Kitt-AI/snowboy#compile-a-python-wrapper

@richardfuchs could you give me the link of the pre-compiled version that doesn't work? I should fix that.
