I encountered an error while running tutorial notebook #71

Closed unknowner-m closed 5 months ago

unknowner-m commented 6 months ago

When I followed the tutorial notebook, I encountered an error in fitting

# Read in the spec
s.read_spec(source_fn, file_dir=source_fd, z=z)

# Preview the spectrum and overlay the initial params
s.plot_spec_ini(inppar_fn, optpar_fn)

This gets the KeyError

I found a problem, that is, I should run in UNIX environment. Now the notebook works well
