HI @quangp

This is common to happen when you change some settings between training

  • Your model was trained with input windows of 24,248 values, but the test sample you’re using has only 12,124 values.
  • This usually happens if:
    • The window size or stride changed after training.
    • You’re testing with data collected under a different sampling frequency or duration.
    • There’s a mismatch between the DSP block output and model input.

Retrain all blocks again with the new settings.
