Encoding matches, integer turns float

edit

Hello I am combining the ensenso ros driver with the mask rcnn ros node. I'm using ros kinetic with the master branch of both packages. I am using an RTX 2080 ti and ubuntu 16.04 with kernel 4.15.0-46-generic.

I have altered the code for the mask rcnn node to accept my own trained data and to accept a mono8 image encoding as input, the input image is stacked onto itself to create a fake bgr image. I have tested this against the bagfile that is included as an example and it is still operational. I created my own launch file:

<launch>
  <arg name="configuratie" value="$(find ensenso_camera)/configs/configuratie.json"/>
  <node pkg="ensenso_camera" type="ensenso_camera_node" name="ensenso_camera_node">
    <param name="settings" value="$(arg configuratie)"/>
  </node>
  <node pkg="ensenso_camera" type="request_data" name="image_stream_node">
    <param name="request_rectified_images" value="true"/>
    <param name="publish_results" value="true"/>
  </node>
  <node pkg="tf" type="static_transform_publisher" name="ensenso_optical_frame" 
    args="0 0 0 0 0 0 world ensenso_optical_frame 100"/>
  <node pkg="mask_rcnn_ros" type="mask_rcnn_node" name="mask_rcnn">
    <remap from="~input" to="/rectified/left/image"/>
    <param name="~visualization" value="true"/>
  </node>
</launch>

However, when I launch my launch file, where the both the camera and the model node are started and have their out and input mapped to each other, the model gives the following error:
