Streamlit's hot-reload re-executes app.py on every interaction, but
sub-modules imported from app.py stay cached in sys.modules across
reruns. When we edit auto_explore.py or auto_hardware.py while
Streamlit is alive, the app keeps using the pre-edit version until a
full Ctrl+C + restart — leading to confusing "unexpected keyword
argument" errors after a signature change.
Force importlib.reload() on our own modules at the top of app.py so
future signature changes land without a full restart. Only reloads if
the module is already in sys.modules (first run just imports normally).
Applied to:
- tests.analytical_visualization.auto_explore
- tests.analytical_visualization.auto_hardware
- tests.analytical_visualization.autosuggest
- tests.analytical_visualization.stage_latencies
- tests.analytical_visualization.memory_layout
Third-party modules (streamlit, matplotlib, pandas, numpy) NOT reloaded
— unnecessary and slow.
