Label audio data using your existing model - Edge Impulse Documentation

This example comes from the Edge Impulse Linux Inferencing Python SDK that has been slightly modify to upload the raw data back to Edge Impulse based on the inference results. To run the example:

Clone this repository:

git clone git@github.com:edgeimpulse/example-active-learning-linux-python-sdk.git

Install the dependencies:

pip3 install -r requirements.txt

Grab your the API key of the project you want to upload the inferred results raw data:

Past the new key in the EI_API_KEY variable in the audio-classify-export.py file. Alternatively, load it from your environment variable:

export EI_API_KEY='ei_xxxx'

Download your modelfile.eim:

edge-impulse-linux-runner --download modelfile.eim

Run the script:

python3 audio-classify-export.py modelfile.eim yes,no 0.6 0.8

Here are the arguments you can set:

modelfile.eim, path the model.eim
yes,no, labels to upload, separated by comas, no space
0.6, low confidence threshold
0.8, high confidence threshold
<audio_device_ID, optional>

In a keyword spotting model, it can give the following results:

python3 audio-classify-export.py modelfile.eim yes,no 0.6 0.8
