Converting "*.dat" to array...

iBayern

I have imported "banana.dat" data file to pythonista... i want to convert it to array using following code...

from numpy import *
DataIn = loadtxt('banana.dat')

But, I got error...I don not know what is the problem.

Copy the full stack, please. Are you on the beta, or on 2.0

Thank you for your quick answers.

The header is:
@relation banana
@attribute At1 real[-3.09,2.81]
@attribute At2 real[-2.39,3.19]
@attribute Class {-1.0,1.0}
@inputs At1, At2
@outputs Class
@data
1.14,-0.114,-1.0
-1.52,-1.15,1.0
-1.05,0.72,-1.0
-0.916,0.397,1.0
-1.09,0.437,1.0
-0.584,0.0937,1.0
1.83,0.452,-1.0
-1.25,-0.286,1.0
1.7,1.21,1.0
-0.482,-0.485,1.0
1.79,-0.459,-1.0

I'm using the version 2.0...Maybe the problem is the header...how can I remove the deader?

You can ignore the lines starting with @ by passing a comments argument to loadtxt. You also need to specify the delimiter, which is a comma in your case, but whitespace by default. This should work:

from numpy import *
data = loadtxt('banana.dat', comments='@', delimiter=',')
