I have been trying to use this projects, I requested and downloaded Original Hey-Snips Dataset. I was able to run utils/preprocess_dataset.py, utils/filter_dataset_to_h5.py, and python wwdetect/CRNN/train.py without problems.
As a result I get tflite files

But when I try to use new models on python demo.py I get this message error. Do you know which can be the cause
