streamlit is not running correctly #489

Streamlit, version 0.88.0

I have forked and cloned the repo and installed all required libs. Now when I streamlit run promptsource/promptsource.py my browser gets http://localhost:8501/ but the interface stays on the high level metrics page no matter which mode I choose. It does not seem to respond to anything. Meanwhile I get a long list of the same lines on my command line:

Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug.
The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().

Not only that, I am unable to use ctrl+C to quit the app:

  Stopping...
  Stopping...
  Stopping...
  Stopping...

This is what I get and it never quits (permanently stopping...). Baffling! I have used the Dataset streamlit app for adding dataset not so long ago and had no issue.
