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 (I guess I have made a structured array) from it but it gets screwed up or I don't get it, likely 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, notice that the number get screwed up in the structured array (not sure who to get a record array, I thought this was but was told it is not) 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), (206933603122, 0, 0.0, 0.0, 0), (808334386, 0, 0.0, 0.0, 0), (3486240, 0, 0.0, 0.0, 0)], [(3219488, 0, 0.0, 0.0, 0), (3153952, 0, 0.0, 0.0, 0), (13561617777439282, 0, 0.0, 0.0, 0), (54074581398322, 0, 0.0, 0.0, 0), (3486240, 0, 0.0, 0.0, 0)], [(3285024, 0, 0.0, 0.0, 0), (3153952, 0, 0.0, 0.0, 0), (206933931058, 0, 0.0, 0.0, 0), (925775666, 0, 0.0, 0.0, 0), (3486240, 0, 0.0, 0.0, 0)], ..., [(3487540, 0, 0.0, 0.0, 0), (3618612, 0, 0.0, 0.0, 0), (206933602866, 0, 0.0, 0.0, 0), (908996661, 0, 0.0, 0.0, 0), (3486240, 0, 0.0, 0.0, 0)], [(3553076, 0, 0.0, 0.0, 0), (3618612, 0, 0.0, 0.0, 0), (13561596370041137, 0, 0.0, 0.0, 0), (62870573495603, 0, 0.0, 0.0, 0), (3486240, 0, 0.0, 0.0, 0)], [(3618612, 0, 0.0, 0.0, 0), (3618612, 0, 0.0, 0.0, 0), (206933798962, 0, 0.0, 0.0, 0), (942552372, 0, 0.0, 0.0, 0), (3486240, 0, 0.0, 0.0, 0)]],
