Following the tutorial (How to build a voice assistant with open source Rasa and Mozilla tools) and I can successfully record audio to a .wav file (on a mac). However, I then get the following error: * recording * done recording Traceback (most recent call last): File "transcribe.py", line 58, in predicted_text = deepspeech_predict(WAVE_OUTPUT_FILENAME) File "transcribe.py", line 51, in deepspeech_predict ds = Model('deepspeech-0.5.1-models/output_graph.pbmm', N_FEATURES, N_CONTEXT, 'deepspeech-0.5.1-models/alphabet.txt', BEAM_WIDTH) File "/usr/local/lib/python3.7/site-packages/deepspeech/__init__.py", line 40, in __init__ status, impl = deepspeech.impl.CreateModel(*args, **kwargs) TypeError: CreateModel() takes at most 2 arguments (5 given) I do see - Successfully installed deepspeech-0.6.1 so I’m wondering if it is a version mismatch problem since the tutorial is geared for 0.5.1 ?

hey @jonathanpwheat, you are correct it’s the problem of version mismatch. it happened with me when I upgraded the deepspeech and the model to version 0.6. I see the CreateModel() arguments were changed the in the newer version. In version 0.5.1, it was : Model(‘deepspeech-0.5.1-models/output_graph.pbmm’, N_FEATURES, N_CONTEXT, ‘deepspeech-0.5.1-models/alphabet.txt’, BEAM_WIDTH) and in version 0.6, it’s this way: https://github.com/mozilla/DeepSpeech-examples/blob/bbac85cc465ad5e68dfc0e365ef1485465db96af/mic_vad_streaming/mic_vad_streaming.py#L164 so better we use version 0.5 :sweat_smile:

I’ve upgraded the code to use the latest everything, Python, Rasa, DeepSpeech 0.6.1 @Emma - is me somehow updating the blog post possible? or commenting on it with changes? Or should I write my own tutorial using current versions (Python / Rasa / DeepSpeech, etc) and have you link to it?

Hi @jonathanpwheat Thank you so much for offering to help us update this, especially since it’s something our community is very interested in! We’re currently discussing the best way to approach it and will get back to you in the upcoming days with clearer next steps. :slight_smile:

Hey @jonathanpwheat, Sorry for the lack of reply here, we are still discussing this and I wanted to let you know before the weekend that we should have more info next week.

No worries, take your time :slight_smile:

Hey… I have deepspeech version 0.5.1 and I have been following the same blog which is mentioned above but after running this command **rasa run --enable-api -p 5005** i am getting this error [Screenshot%20from%202020-03-16%2018-06-48] TypeError: CreateModel() takes at most 2 arguments (5 given) what changes are needed for me to remove this error. @JiteshGaikwad @jonathanpwheat @Emma Please help.

Hey @Abbas, I think so there is some version problem of DeepSpeech that you are using or the model. Can you please recheck the Deepspeech version and model version of DeepSpeech that you are using?

@JiteshGaikwad I have been using this version TensorFlow: v1.14.0-21-ge77504a DeepSpeech: v0.6.1-0-g3df20fe Sorry it was my mistake i have been using deepspeech version 0.6.1 not 0.5.1 now what are the changes i need to follow for this version of deepspeech could you please guide.

You just need to downgrade the Deepspeech version to 0.5.1 and use the 0.5.1 model, it will solve the error.
