Dependency on python module `sys`
I am working on a ROS noetic package which includes a node which imports the python sys
module (in Ubuntu 20.04 with python3).
Is it necessary to declare the dependency on the sys
module in the package.xml
file?
If yes, which
<exec_depend>
is required? I had a look at the documentation on the documentation to python module dependencies, but I have not been able to find the <exec_depend> forsys
in the rosditro repository.If no, why is it not necessary to declare dependency on this import?
