As of [Numpy 2.4.0](https://numpy.org/doc/stable/release/2.4.0-notes.html#raise-typeerror-on-attempt-to-convert-array-with-ndim-0-to-scalar), converting an 0-dimensional array to a scalar is now a TypeError, following the expiration of a lengthy deprecation period. This change detects the situation and adjusts the types accordingly before passing them to tensorboard.
