Ich generiere einen Datenrahmen, der so aussieht summaryDF):

   accuracy        f1  precision    recall
0     0.494  0.722433   0.722433  0.722433
0     0.290  0.826087   0.826087  0.826087
0     0.274  0.629630   0.629630  0.629630
0     0.278  0.628571   0.628571  0.628571
0     0.288  0.718750   0.718750  0.718750
0     0.740  0.740000   0.740000  0.740000
0     0.698  0.765133   0.765133  0.765133
0     0.582  0.778547   0.778547  0.778547
0     0.682  0.748235   0.748235  0.748235
0     0.574  0.767918   0.767918  0.767918
0     0.398  0.711656   0.711656  0.711656
0     0.530  0.780083   0.780083  0.780083

Da ich weiß, wie jede Zeile in dieser Zeile aussehen soll, verwende ich diesen Code, um die Namen der einzelnen Zeilen festzulegen (dies sind nicht die tatsächlichen Zeilennamen, sondern nur aus Gründen des Arguments).

summaryDF = summaryDF.set_index(['A','B','C', 'D','E','F','G','H','I','J','K','L'])

Allerdings bekomme ich:

level = frame[col].values
  File "/Users/me/anaconda/lib/python2.7/site-packages/pandas/core/frame.py", line 1797, in __getitem__
    return self._getitem_column(key)
  File "/Users/me/anaconda/lib/python2.7/site-packages/pandas/core/frame.py", line 1804, in _getitem_column
    return self._get_item_cache(key)
  File "/Users/me/anaconda/lib/python2.7/site-packages/pandas/core/generic.py", line 1084, in _get_item_cache
    values = self._data.get(item)
  File "/Users/me/anaconda/lib/python2.7/site-packages/pandas/core/internals.py", line 2851, in get
    loc = self.items.get_loc(item)
  File "/Users/me/anaconda/lib/python2.7/site-packages/pandas/core/index.py", line 1572, in get_loc
    return self._engine.get_loc(_values_from_object(key))
  File "pandas/index.pyx", line 134, in pandas.index.IndexEngine.get_loc (pandas/index.c:3824)

  File "pandas/hashtable.pyx", line 694, in pandas.hashtable.PyObjectHashTable.get_item (pandas/hashtable.c:12231)
KeyError: 'A'

Ich habe keine Ahnung, was ich falsch mache und habe weit und breit recherchiert. Irgendwelche Ideen
