What's Changed

Major Changes 🛠

• Add support for random Generators in Numba backend by @ricardoV94 in #69. This PR introduces multiple (long delayed) breaking changes regarding RandomVariables:
  • Number of default inputs is reduced from 3 (rng, size, dtype) to 2 (rng, size). Other than changes in the signature, any code that relied on positional indexing to split these parameters from the distribution parameters like dist_params = x.owner.inputs[3:] must be updated. A helper RandomVariable method dist_params can be used instead like dist_params = x.owner.op.dist_params(x.owner)
  • A distinct RandomVariable Op must now be created for each distinct dtype. Comparisons that don't care about this distinction that used to look like x.owner.op == normal should be replaced by isinstance(x.owner.op, NormalRV)
  • Support for legacy RandomState variables removed. Rng variables must now be of RandomGenerator type. randint, which only worked with RandomState rngs was removed. Use integers instead.
  • size=None is no longer internally converted to size=(). size=() now behaves differently than size=None (just like Numpy)
  • Definition of ndims_params and ndim_supp is deprecated in favor of a numpy-like gufunc signature such as (),(p)->(p) for MultinomialRV.ndims_params and ndim_supp are now derived from the signature, and available only as properties of initialized RandomVariable Ops.
  • Explicit expand_dims are now introduced for parameters that are being broadcasted internally by the RandomVariable Op, like Elemwise and Blockwise do.
