"get_nvds_buf_surface" is said to be absent in pyds

“get_nvds_buf_surface” is said to be absent in pyds.

I want to get the array in numpy format via “pyds.get_nvds_buf_surface()” according to the following documentation.
URL:https://docs.nvidia.com/metropolis/deepstream/5.0/python-api/Methods/methodsdoc.html?highlight=nvds_buf_surface

However, the following error occurs.

Error

    frame_rgba = pyds.get_nvds_buf_surface(gst_buffer, g_count)
AttributeError: module 'pyds' has no attribute 'get_nvds_buf_surface'

Code

def osd_sink_pad_buffer_probe(pad,info,u_data):
    global g_count
    print(f "gcount:{g_count}")
    frame_number=0
    #Intiallizing object counter with 0.
    obj_counter = {
