AttributeError: module ‘pyds’ has no attribute ‘gst_buffer_get_nvds_batch_meta’


When I execute the deepstream sample programs (python versions) provided in github, it displays the following error message. My file is already in the folder where the gst_plugin_path is set.

Traceback (most recent call last):
File “”, line 62, in osd_sink_pad_buffer_probe
batch_meta = pyds.gst_buffer_get_nvds_batch_meta(hash(gst_buffer))
AttributeError: module ‘pyds’ has no attribute ‘gst_buffer_get_nvds_batch_meta’
