Error while running detection_from_microphone.py

[manushaanabham]

I am facing following issue (attached the screen shot) while running detection_from_microphone.py with the give pre-trained model available in the folder docs/models/alexa.md

Using the following command python detect_from_microphone.py --model_path ~/Desktop/wakeup_word/openWakeWord/docs/models/alexa.md

Error message:- ValueError: Model provided has model identifier 'del ', should be 'TFL3'

Thanks in advance

When using this script you need to provide the path to the .tflite or the .onnx models files, you are currently passing the path to a markdown (.md) file.

You can download these automatically using the openwakeword.utils.download_models() command, or download them manually from this release.

Thanks for your reply I have downloaded the files from the link you have provided and executed the below command

python examples/detect_from_microphone.py --model_path alexa_v0.1.tflite --inference_framework melspectrogram.tflite

Still i am facing some issue. I have attached the screenshot of error please help me to solve the issue

Quick workaround.

• Create the following python script after installing openwakeword

  pip install openwakeword

#create missing directories
import os
import openwakeword as oww

# Create the directory structure
models_path = os.path.join(os.path.dirname(oww.__file__), 'resources', 'models')
os.makedirs(models_path, exist_ok=True)
print(f"Created directory: {models_path}")

# Download the models
oww.utils.download_models()
print("Models downloaded successfully.")

# Verify the downloaded files
files = os.listdir(models_path)
print(f"Files in {models_path}:")
for file in files:
    print(f" - {file}")

Sample Output

python download_openwakeworkd_models.py
