The LaTeX snippet use vimtex to tell whether the current consor is in a math environment so you need to install it first.
We make helper functions available to multiple snippet files by defining helper functions in a file pythonx/snippet_helpers.py.
Note that Vim will load the snippet_helpers.py one time only. That means that any changes you make to the helper functions in snippet_helpers.py won’t be seen by your snippet files until you reboot Vim.
See here and :help UltiSnips-globals for more infomation.
