Just starting with sedfitter. Installed latest versions of the package and dependencies. Running python 3.7.6. Testing with example.py (verbatim from sedfitter/examples except for paths to data). fit function completes with no errors, but plot function dies with:
UnitConversionError: '' (dimensionless) and 'um' (length) are not convertible
Can't find the culprit. Any suggestions?
Thanks--
