To narrow down this issue, please check the following:
- please check the configuration file, if using the same model, the deepstream configuration of model should be the same.
- if still failed, please compare the logics and Gstreamer pipeline with C code, here is the topic about " Generate GStreamer Pipeline Graph" DeepStream SDK FAQ - #10 by mchi
- if still failed, please simplify the python code, for example, modify the simplest sample deepstream_test_1.py to run the model.
