Rosdep pip instead of apt

My node needs the Sympy Python package in version > 1.1.2 (otherwise plane/ray intersections are wrong)

So far I had added <depend>python-sympy</depend> to my package.xml to have rosdep take care of the installation. However, apt show python-sympy shows version 0.7.6.1-1, which won't work. After I removed apt's package and did pip install sympy, I got version 1.3, which is good.

Can I have rosdep use pip instead of apt? Do I need to do a pull request to add [python-sympy-pip] in https://github.com/ros/rosdistro/blob... ?

We generally don't want rosdep rules that override the system version with a pip version.

On your own system you can create a custom rosdep rule that will replace the apt one with pip if you want. But in general for deployment and sharing you should plan to use the system version.

Please see discussion at: https://github.com/ros/rosdistro/pull... for more context.
