PHATE incompatible with NumPy ≥2.0 despite requirement specifying numpy>=1.16.0

[nishuang83]

Describe the bug
PHATE currently declares a dependency on numpy>=1.16.0, which allows installation alongside NumPy 2.x. However, PHATE appears to be incompatible with NumPy 2.x releases — it fails at runtime when used with these versions, even though installation completes without error.

To Reproduce

1. Create a new environment in python 3.10 and install the latest NumPy:

pip install numpy
# installs numpy==2.2.6

2. Install PHATE:

pip install phate

3. Try to import or use PHATE:

import phate

Expected behavior
PHATE should work well.

Actual behavior
Show some error

Then, I install 1.x version NumPy:

pip uninstall -y numpy
pip install "numpy<2"

PHATE runs without issues.

System information:

Output of phate.__version__: '1.0.11'

Output of pd.show_versions():

Additional context
The issue does not trigger during installation (since the current requirement allows NumPy 2.x), but happends only at runtime.
A version check or dependency update would prevent confusion for users installing PHATE in new environments.
