Environment setup dependency conflict

[Augensteern]

When following the installation instructions, I encounter a critical dependency conflict that prevents environment setup. The error indicates incompatible pyarrow version requirements between three packages:

• ibllib 2.34.0 depends on pyarrow (no version specified, likely uses latest compatible)
• datasets 2.17.1 requires pyarrow>=12.0.0
• ray[tune] 2.9.3 requires pyarrow<7.0.0 and >=6.0.1

These requirements create an unresolvable conflict because datasets needs pyarrow ≥12.0.0 while ray[tune] restricts it to <7.0.0. The pip dependency resolver fails with ResolutionImpossible error.

Hi, perhaps we could relax the version constraint on ray[tune]. It’s not necessary for core model running and is mainly used for hyperparameter tuning, while datasets is required for data loading.
