I think you are using select incorrectly. Select is pretty similar to "find" but it returns a view object instead of an index.a=vw.select(2,4)
a = vw.select(a=2)
What are you trying to do? You might be trying to do a = vw[2:4] which is a slice.
if you want to return the rows with a between 2 and 4
a = vw.remapwith(vw.filter(lambda row: row >=2 and row < 4))
Traceback (most recent call last):
File "<input>", line 1, in ?
ValueError: Object has no usable attributes
Python 2.3.1 Metakit version: 2.4.9.2
What am I missing?
