Hi,

apparently xgbfir does not support the recently released of xgboost 0.7:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

~/anaconda3/lib/python3.6/site-packages/xgbfir/main.py in saveXgbFI(booster, feature_names, OutputXlsxFile, MaxTrees, MaxInteractionDepth, MaxDeepening, TopK, MaxHistograms, SortBy)

    590         if 'booster' in dir(booster):
--> 591             booster = booster.booster()
    592         else:
    593             return -20

TypeError: 'str' object is not callable

the issue is solved with a new update.
