Incompatibility with Numpy 2.0

[thorstenhater]

I cannot import tvb in an environment with numpy>=2.0 installed due the use of a removed function. However, tvb does not require numpy<2.0

Describe the bug

See above.

Steps to reproduce

✔❯ pip install numpy==2.0 tvb-library
✘❯  python3 -c 'import tvb.simulator.lab'
/Users/hater/src/models/arbor-epilepsy/.direnv/python-3.12/lib/python3.12/site-packages/tvb/datatypes/surfaces.py:60: UserWarning: Geodesic distance module is unavailable; some functionality for surfaces will be unavailable.

TypeError: can_cast() does not support Python ints, floats, and complex because the result used to depend on the value.
This change was part of adopting NEP 50, we may explicitly allow them again in the future.

Expected results

No error.

Actual results

See above.

Additional information

✔❯  pip list | rg tvb
tvb-contrib               2.9
tvb-data                  2.0
tvb-library               2.9

Thanks for pointing this issue. We marked in the latest release tvb-library==2.9.1 the requirement to have numpy<2.0 for now. We will look into numpy 2.0 compatibility sometime in the future (unfortunately I can not say more exactly when).
