I have a concern related to a result shown as -1#IND in my interpreter (blue letters, not red warnings) that I am getting after a bunch of numpy code and I do not really know the meaning. Can you please help me with WHAT DOES -#IND MEAN? could it be related to previous -#INF or NaN that may emerge during the calculations before the final result?

Absolutely. -1#IND means "negative indefinite". Indefinite is one of
the special values defined in IEEE 754. Dividing by zero gives infinity
(1#INF), but dividing 0 by 0 results in "indefinite" because it has no
defined meaning.
