Error when drawing lines or circle using pyds.NvDsDisplayMeta

Hi all ,
I am trying to draw some circles on output video using pyds.NvDsDisplayMeta but got Index error when index reaches beyond 15.

Sample code:
display_meta.num_labels = 20
for i in range(20):
py_nvosd_circle_params = display_meta.circles_params[i]
py_nvosd_circle_params.radius =2

Error description:
py_nvosd_line_params = display_meta.line_params[idx]
IndexError: list index out of range
