“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 = {
        PGIE_CLASS_ID_NO_MASK:0,
        PGIE_CLASS_ID_MASK:0
        # PGIE_CLASS_ID_VEHICLE:0, PGIE_CLASS_ID_VEHICLE:0,

    }
    num_rects=0

    gst_buffer = info.get_buffer()
    If not gst_buffer. print("Unable import pydsto get GstBuffer ")
        print("Unable import pydsto get GstBuffer ")
        return

    # show img
    frame_rgba = pyds.get_nvds_buf_surface(gst_buffer, g_count)
    cv2.imshow("Streamk",frame_rgba)

Hi natukage405, this binding is only available in the newly announced Python bindings release v0.9. It requires DeepStream SDK 5.0 Developer Preview. You can download both at https://developer.nvidia.com/deepstream-getting-started

You can find the sample app using this binding at https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/tree/master/apps/deepstream-imagedata-multistream
