[dodo_detector_ros-1] process has died

I followed the installation process in this way: Having ROS kinetic installed in Ubuntu v16 with Python, installed:

dodo_detector

pip install git+https://github.com/douglasrizzo/dodo_detector.git

TensorFlow Object Detection API

pip install tensorflow
sudo apt-get install protobuf-compiler python-pil python-lxml python-tk
pip install --user Cython
pip install --user contextlib2
pip install --user jupyter
pip install --user matplotlib

dodo_detector_ros

roscd; cd ../src; git clone https://github.com/douglasrizzo/dodo_detector_ros.git

Then I use an Intel Sense camera that is integrated in a mobile robot so I change the launcher _detectkinect.launcher accordingly:

<?xml version="1.0"?>
<launch>
    <remap from="/camera/rgb/image_color" to="/camera_floor/driver/color/image_raw"/>
    <remap from="/camera/depth/points" to="/camera_floor/driver/depth/color/points"/>

    <node name="dodo_detector_ros" pkg="dodo_detector_ros" type="detector.py" output="screen">
        <rosparam command="load" file="$(find dodo_detector_ros)/config/main_config.yaml"/>
    </node>
</launch>

Once I make sure that the topics are being published, I execute your package and it gives me the following error:

What am I doing wrong so that your package does not work?
