I would like to import the following csv as strings not as int64. Pandas read_csv automatically converts it to int64, but I need this column as string.
ID

df = read_csv('sample.csv')
df.ID

Unfortunately using converters gives the same result.
df = read_csv('sample.csv', converters={'ID': str})
df.ID

Just want to reiterate this will work in pandas >= 0.9.1:
In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]:

I'm creating an issue about detecting integer overflows also.
