Why is scalar turned to 1d np array

[tianshub]

Describe the bug
Why is scalar turned into a 1d np array here:

tensorboardX/tensorboardX/x2num.py

Lines 22 to 23 in ca5072b

	if np.isscalar(x):
	return check_nan(np.array([x]))

instead of just np.array(x)?

This result in warning messages like:

DeprecationWarning: Conversion of an array with ndim > 0 to a scalar is deprecated, and will error in future. Ensure you extract a single element from your array before performing this operation. (Deprecated NumPy 1.25.)

in the summary.py when converting back to float.

Minimal runnable code to reproduce the behavior

from tensorboardX import SummaryWriter
...

Expected behavior
Proper type conversion.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment
What is the result of
pip list|grep -E "torch|proto|tensor"
If the version is too old, please try to update first.

Python environment
Which version of python are you using? Did you use Andconda or Virtualenv?

FYI this Deprecation Warning is now an error in numpy >= 2.4.0, so the need to fix this has become somewhat more relevant.
