Can't find librivermax.so.0 and libtritonserver.so

I am trying to execute the example here deepstream_python_apps/apps/deepstream-imagedata-multistream at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub . After your suggestion here Deserialize engine failed because file path: .../resnet10.caffemodel_b1_gpu0_int8.engine open error I tried to run the sample within the official deepstream container.
Gstreamer is giving me errors reporting that it cannot load plugins because their files do not exists. How do I get them?
I am running on a T4.

Output:

Frames will be saved in  frames

In order to reproduce the issue you can create the two following files in the same directory.

Dockerfile:

FROM nvcr.io/nvidia/deepstream:6.0-samples
ENV GIT_SSL_NO_VERIFY=1
RUN apt install -y git python-dev python3 python3-pip python3.6-dev python3.8-dev cmake g++ build-essential \
    libglib2.0-dev libglib2.0-dev-bin python-gi-dev libtool m4 autoconf automake wget
RUN apt install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
RUN pip3 install --upgrade pip
RUN pip3 install numpy opencv-python
RUN echo '/usr/local/lib/gstreamer-1.0' >> /etc/ld.so.conf
RUN ldconfig
RUN cd /opt/nvidia/deepstream/deepstream-6.0/sources && \
    git clone https://github.com/NVIDIA-AI-IOT/deepstream_python_apps.git
RUN cd /opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps && \
    git submodule update --init
RUN wget https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/releases/download/v1.1.0/pyds-1.1.0-py3-none-linux_x86_64.whl
RUN pip3 install pyds-1.1.0-py3-none-linux_x86_64.whl
COPY start_example.sh start_example.sh
RUN rm -rf ~/.cache/gstreamer-1.0/

start_example.sh :

cd /opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/apps/deepstream-imagedata-multistream
python3 deepstream_imagedata-multistream.py rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov frames

Then run:

docker build . -t deepstream-custom
docker run --gpus '"'device=0'"' -it --rm -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY  deepstream-custom sh start_example.sh

Files librivermax.so.0 and libtritonserver.so can’t be find in the system.

EDIT: I even tried changing base image to use the deepstream:6.0-triton but then I got the following errors:
