SyntaxWarning

[hschreiber]

There are several SyntaxWarning in the notebooks when calling them from jupyter lab:

• Tuto-GUDHI-DTM-filtrations.ipynb

In cell [1]:

TDA-tutorials/utils/utils_dtm.py:155: SyntaxWarning: invalid escape sequence '\ '
  """

• Tuto-GUDHI-kPDTM-kPLM.ipynb

In cell [4]:

I don't know how problematic they are as they don't seem to impact the actual code. Most of those are just latex symbols which are not recognized. I can't say if those are from jupyter lab, or if I am missing a package, or if they are actually syntax errors.

IIUC we should either use raw string literals (which means that \ is not special), or protect those \ by writing \\.
