Deepstream Error: gst-library-error-quark: Configuration file parsing failed (5)

Hello,

I0m trying to run the Deepstream Example #1. I got this error:

Error: gst-library-error-quark: Configuration file parsing failed (5): /dvs/git/dirty/git-master_linux/deepstream/sdk/src/gst-plugins/gst-nvinfer/gstnvinfer.cpp(769): gst_nvinfer_start (): /GstPipeline:pipeline0/GstNvInfer:primary-inference:
Config file path: dstest1_pgie_config.txt

What I did was copy /deepstream-5.1/ to my Documents path folder. I did it just for edit permission.

I run the example like this:
jj@jj:~/Documents/deepstream/avengers-deepstream/deepstream-5.1/sources/deepstream_python_apps/apps/deepstream-test1$ python3 deepstream_test_1.py …/…/…/…/samples/streams/sample_720p.h264

Thank you

#!/usr/bin/env python3
