The new NumPy 2.4.0 is more strict when implicitly converting 1-element arrays to scalars. It doesn't do that anymore, causing the TF1 Pythonization tests to fail (see log below). This actually pointed to a real mistake in setting up the test, where a 2D array was used to define the TFormula parameters while it should be a 1D array. ```txt 962/3718 Test root-project#93: pyunittests-bindings-pyroot-pythonizations-pyroot-pyz-tf-pycallables ..............................***Failed 3.05 sec test_callable (tf_pycallables.TF1.test_callable) Test function provided as callable ... ok test_evalpar (tf_pycallables.TF1.test_evalpar) Test the 2D Numpy array pythonizations for TF1::EvalPar ...
