openai_ros on Ubuntu Focal + ROS Noetic

edit

Hi, I could solve the issue by changing a line in "your_ws/src/openai_ros/openai_ros/package.xml."

I guess that you can find the code <build_depend>python-catkin-pkg</build_depend> on line 14 or around it. Although Noetic works on Python3 basically, this code declares catkin-pkg for python2. So, I changed the code to <build_depend>python3-catkin-pkg</build_depend> or <build_depend>python3-catkin-pkg-modules</build_depend>. Sorry for the vagueness since it has been a while since I dealt with it. But, either, or both, of them worked well for me. I hope it is also the case for you.

Hi,

I just tested to download the fetch simulation and execute an example for fetch robot and worked in ROS Noetic. This is one of the exercises in the course of Openai_ROS: OPENAI_ROS course. There is everything ready to go. The noetic version will be there in the next week form writing this post. The procedure I followed:

1) Setup in Ubuntu20 ROS Noetic and create a catkin_ws.

2) Inside it downloaded the packages relevant for your sim

3) Compiled through catkin_make 4) Installed needed dependencies. The relevant for Openai_ros are:

    pip3 install --ignore-installed \
tensorflow \
gym \
wandb \

You might have to install other ROS related packages depend on what you need

5) Execute you open ai Algorithm.

You should be able to download the source and build. As the readme says, clone the repo into your workspace and build the package using catkin build openai_ros (or catkin_make openai_ros depending on your toolset). I was able to build in bionic/melodic.

rosdep will probably need the specific version of ubuntu+ros installed. If you run into missing packages errors, you can install them manually using apt install ros-noetic-<package>
