Also: ROS Answers is a beginners forum, so we're happy to help, but such simple things as installing packages is really something that has been asked and answered many times before and is documented. Please make the effort to search first and save us all the time to answer it again.

Just as any other package that has been released:

sudo apt-get install ros-$release-ros-numpy

Where $release is the name of the ROS release that you have installed.

This does not work for ROS Melodic

Which is to be expected, seeing as the package has not been released into Melodic.

See ros_numpy and status_page/ros_melodic_default.html?q=numpy.

Note also I wrote:

Understood. Your answer was written before Melodic was released, and is now outdated. This is not "to be expected" for anyone using any of the currently recommended ROS distributions in 2020.

The "to be expected" part was responding to the fact that you stated it doesn't work for Melodic. That is certainly to be expected, as it hasn't been released for that version of ROS.

I don't really see how that would not be expected. No matter which version of ROS you are using: if a package has not been released for it, you cannot use apt to install it (on Debian/Ubuntu).

For newer versions of ROS, such as Melodic, you can clone ROS numpy locally and install using

git clone
cd ros_numpy/
python install

Or, since it's 2020, you can use Python3:

python3 install

Seeing as this is a ROS package, using to install it (at least in ROS 1) is not the recommended procedure.

If you're going to install something from sources, at least follow the correct workflow: #q252478.
