AttributeError: module 'numpy' has no attribute 'bool'.
`np.bool` was a deprecated alias for the builtin `bool`. To avoid this error in existing code, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.bool_` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Start at models/encoder/audio.py in trim_long_silences, where the traceback identifies the failing NumPy boolean conversion. Trace the call from control/mkgui/app.py through control/mkgui/base/ui/streamlit_ui.py, then run demo_toolbox.py or the web synthesis mode under Python 3.9. Done means synthesis no longer stops at the reported NumPy attribute error.
