realsense ROS wont start with roslaunch realsense2_camera rs_camera.launch

I am trying to get the realsense ROS wrapper installed for my D435

I have followed the instructions here: https://github.com/intel-ros/realsense/tree/6f2c7c86208f4b5f653e4c15cb1ca6a3515f3b09#installation-instructions which says... install librealsense SDK, install Kinetic then install realsense ROS. All of which I have done but when I get to the line

$ roslaunch realsense2camera rscamera.launch

it returns

[rscamera.launch] is neither a launch file in package [realsense2camera] nor is [realsense2_camera] a launch file name The traceback for the exception was written to the log file

Any ideas why its doing this? Also, where is the log file?

I am using Ubuntu 16.04 and ROS kinetic. I can also confirm that the realsense viewer is working as it should with the latest firmware

Ros cannot find the package, did you source the setup.bash located in your catkin_ws/devel?

Thanks, yes I did, just double checked though. Still get the same error after sourcing. The source line is in .bashrc as well: source ~/catkin_ws/devel/setup.bash

Sorry, it was my own stupid mistake.

I missed out the 'clone' part in the realsense install instructions. Works OK now, albeit with a couple of warnings:

Is it normal?

When using rqt_image_view, can you see the images streamed?

I do yes. Thanks for your time and answers.
