I changed it so to override the variable formatting instead of having to call a seperate command you can just do `print <tensor>`

I also add one for sizes

If you use the codelldb extension be sure to add:
    `"lldb.launch.initCommands": ["command source ${env:HOME}/.lldbinit"]`
    To your setttings .json

# automatically load the pytorch_lldb extension.
#
# lldb automatically tries to load this file whenever it is executed from the
# root of the pytorch repo, but by default it is not allowed to do so due to
# security reasons. If you want to use pytorch_lldb, please add the following
# line to your ~/.lldbinit (i.e., the .lldbinit file which is in your home
# directory, NOT this file):
# settings set target.load-cwd-lldbinit true
# setting set escape-non-printables false
#
# Alternatively, you can manually load the pytorch_lldb commands into your
# existing lldb session by doing the following:
# (lldb) command script import tools/lldb/pytorch_lldb.py
command script import tools/lldb/pytorch_lldb.py
