Tensorflow cannot load libcusolver.so.10

You may have the following error message while running import tensorflow

 Could not load dynamic library 'libcusolver.so.10'; dlerror: libcusolver.so.10: cannot open shared object file: No such file or directory

To resolve the issue, type either one of the two below commands depending on where is libcusolver.so.11 in your system

sudo ln -s /usr/local/cuda/lib64/libcusolver.so.11 /usr/local/cuda/lib64/libcusolver.so.10
# OR 
sudo ln -s /usr/lib/x86_64-linux-gnu/libcusolver.so.11 /usr/lib/x86_64-linux-gnu/libcusolver.so.10

Issue with reading xacro file on ROS-Melodic

This is a known issue in the community and xacro 1.14.13 fixes this. However, as of March 10, 2022, it is not synced with the public ros repositories. You can either install this version from the source or via the ros-testing repositories. The instructions for doing the same can be found here: http://wiki.ros.org/TestingRepository
