I've been getting this message from pip:

DEPRECATION: mermaid 0.3.2 has a non-standard dependency specifier torch>=1.7torchvision. pip 23.3 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of mermaid or contact the author to suggest that they release a version with a conforming dependency specifiers.
