Could not view camera image on RViz

[atinfinity]

I tried to use your Dockerfile.
But, I could not view camera image on RViz.

I think that this Dockerfile has the following problem.

• This camera image is compressed image
• But, ros-melodic-compressed-image-transport is not installed in Dockerfile

Is my understanding correct?

Some Autoware packages require image_raw.
But, LG Simulator publish compressed image.
So, I think that you had better install ros-melodic-compressed-image-transport on Dockerfile.

OK, I will add compressed-image-transport to the dependency of this package and rosdep will solve dependency.

[hakuturu583]

I added it this package to package.xml

Thanks for your help! 👍

@hakuturu583 I tried to run docker build using Dockefile of this project.
But, I could not build. Could you please check again?

E: Unable to locate package ros-melodic-compressed-image-transport
ERROR: the following rosdeps failed to install

I have the same problem. This issue is also related to the installation of Python packages.

Issue: Apt repository in the docker image is not updated.
Solution: Run RUN apt update before rosdep install.

This issue prevents participants from installing additional python packages such as tensorflow-gpu, as rosdep install tries to install python packages (including python-pip) using apt (though Q & A web page says that you can do it ...)

I hope you can fix this issue as soon as possible.

@hakuturu583
I have the same problem.

[hakuturu583]

Sorry, we checked our internal docker file in our evaluation environment and we found
RUN apt-get update before we run rosdep install.
So, it will be no problem in eval environment.
I will fix example dockerfile soon.

#16 was merged. So, I closed this issue.
