I must be missing something simple. I have a list of lists data = "[[' 0',
' 0', '234.0', '24.0', ' 25'], [' 1', ' 0', '22428.0', '2378.1', '
25'],......" and what to make a record array from it but it gets screwed up
or I don't get it, maybe both. Notice that at this stage the items are
strings, not numbers, and there is whitespace not sure this matters.
Here is what is happening
adata = numpy.array(data,numpy.float64)
>>> adata
array([[ 0.00000000e+00, 0.00000000e+00, 2.34000000e+02,
2.40000000e+01, 2.50000000e+01],
...,
[ 4.77000000e+02, 4.77000000e+02, 2.07000000e+02,
4.58000000e+01, 2.50000000e+01]])
This is what I would expect except it is not a record array.
This is not what I expect. I think I have tried every iteration including
using numpy dtaypes numpy.int32 or bdata = numpy.array(data, dtype = [('x',
int),('y', int),('mean',float),('stdv',float),('npixcels',int)])
What am I missing?
bdata = numpy.array(data, [('x', int),('y',
int),('mean',float),('stdv',float),('npixcels',int)])
>>> bdata
array([[(3153952, 0, 0.0, 0.0, 0), (3153952, 0, 0.0, 0.0, 0),
