I'm using Mac os 10.12.5 with python2.7
when I run the demo.py, got this exception. seems like a C++ error

ERROR (ExpectToken():snowboy-io.cc:166) Expected token "<KwInfo>", got instead "<LicenseStart>".
libc++abi.dylib: terminating with uncaught exception of type std::runtime_error: ERROR (ExpectToken():snowboy-io.cc:166) Expected token "<KwInfo>", got instead "<LicenseStart>".

Where did you get your model? Looks like your model has license attached to it, and if that is the case, we should have sent you a updated decoder offline.

NanoPi NEO Plus2 has the same error while using lib/aarch64-ubuntu1604/libsnowboy-detect.a.

which model are you using? If you are using our public models, you are not supposed to see those errors.

[bacek]

I have same issue with public jarvis.umdl.

[chenguoguo]

Very wired. I just tried the following and it works:

1. Checkout out the repository

2. Make under swig/Python, cd swig/Python; make

3. Enter examples/Python and apply the following patch for the jarvis.umdl setting

   
   diff --git a/examples/Python/demo.py b/examples/Python/demo.py
   index 305b8b6..7d7caf4 100644
   --- a/examples/Python/demo.py
   +++ b/examples/Python/demo.py
   @@ -24,7 +24,9 @@ model = sys.argv[1]
   # capture SIGINT signal, e.g., Ctrl+C
   signal.signal(signal.SIGINT, signal_handler)

-detector = snowboydecoder.HotwordDetector(model, sensitivity=0.5) +detector = snowboydecoder.HotwordDetector(model,

• sensitivity=[0.8, 0.80],

• apply_frontend=True) print('Listening... Press Ctrl+C to exit')

  main loop

Then run it python demo.py resources/models/jarvis.umdl

I'm using node.js bindings (1.2). Probably related to https://github.com/Kitt-AI/snowboy/issues/341#issuecomment-364838771

[chenguoguo]

Yes you have to use 1.3 or above; or you can compile your own node bindings. @bacek

[bacek]

Unfortunately 1.3 node bindings crashing on loading model (any model) with error on funmap. And I didn't have time to investigate it.
