I get a surprise error message when trying to save the results.
File “/Users/direc/anaconda/lib/python2.7/site-packages/pandas/indexes/base.py”, line 2271, in get_indexer
raise InvalidIndexError(‘Reindexing only valid with uniquely’
InvalidIndexError: Reindexing only valid with uniquely valued Index objects
It is apparently caused by the following line in my script:
trials.saveAsWideText(fileName, delim=’;’, appendFile=False, encoding=‘utf-8’)
I am getting this all of the sudden after many experiments with a very similar structure and partly identical code, but unfortunately have no idea what aspect of my changes caused this behavior. I am getting it on at least two systems (Mac, Win) and probably also on a third (Linux) where I discovered that data files are created but empty.
Any suggestions are very welcome.
