Error when use svm_model.sv_indices

[wly93]

i got the type of sv_indices is "ctypes.wintypes.LP_c_long"
how can i convert it to numpy array or a list

[wly93]

i used libsvm in python

[cjlin1]

but I think it's a list:

>> s = m.get_sv_indices() >> s

[3, 14, 29, 38, 41, 45, 47, 48, 59, 60, 68, 70, 82, 83, 92, 94, 95, 96, 98, 102, 106, 109, 111, 113, 117, 130, 131, 132, 138, 143, 145, 147, 161, 162, 170, 176, 178, 179, 183, 192, 194, 204, 209, 211, 227, 231, 232, 234, 241, 244, 249, 253, 259, 263, 265, 2, 4, 5, 6, 11, 12, 15, 16, 20, 24, 25, 27, 30, 32, 53, 61, 65, 67, 72, 73, 74, 75, 77, 84, 85, 86, 88, 97, 99, 107, 119, 125, 129, 135, 136, 140, 142, 144, 154, 159, 165, 166, 169, 171, 181, 185, 186, 188, 191, 197, 201, 208, 210, 212, 218, 219, 226, 233, 235, 239, 245, 257, 267, 269]
