Hello there,
I am getting the above error on the following line
n_frame = pyds.get_nvds_buf_surface(hash(gst_buffer), frame_meta.batch_id)

I need to extract the frame to draw the bonding box on it,

what can I change to accomplish this? please check the .py file attached for reference

Nope

gst-nvinfer can’t output RGBA format, you can not use get_nvds_buf_surface in gst-nvinfer src pad probe function.

Please refer to the sample of deepstream_imagedata-multistream.py.
