1.12

Version 1.12 sees major performance improvements for eager execution.

Other highlights

• sort now supports sorting by key. Added *sort aliases.
• The linear solver scipy-lsqr is now available, scipy-direct now performs a convergence check by default.
• Rank-deficient linear systems are now solved by discarding n rows/cols from the sparse matrix.
• New functions unravel_index
• New submodule phiml.math.perm
• New aliases p... for reducing all primal dims
• where() now supports dataclasses
• Add dataclasses.copy()

1.11.0

This release adds official support for custom dataclasses in the phiml.dataclasses module.

Highlights

• Dataclass decorators @sliceable, @data_eq
• Replacing some fields of a dataclass instance keeps all unaffected caches from @cached_property
• Dataclasses no longer need to handle None values in comparisons when used in JIT or other tracing.
• Shorthand function *max, *min, *prod, *pack for specific dim types
• New syntax for item name renaming while slicing, e.g. tensor['y,x->a,b] selects the slices x and y and renames them.
• Add squeeze to remove singleton dims
• Improve formatting of sparse matrices
• clip() now accepts Shape for the upper limit
• Dim packing functions can now also be used for unpacking when passing one input and multiple output dims.

1.10.0

This release adds a lot of new functionality and pushes the new paradigm of letting users define custom types as @dataclass with @cached_property derived values.

• Expanded support for non-uniform tensors and sparse matrices
• Add tensor transpose shorthands Tensor.Ti, .Tc, .Ts and Tensor.dim.T. The old transpose is now called swap_axes.
• Add save, load to store using any (nested) tensor data using NumPy
• Add ncat and tcat variants (ccat, icat, scat, dcat)
• Add random_permutation, pick_random
• Functions such as slice, max, min now accept range to return the gather indices
• Add softmax, nan_to_0, counter_intersections
• Multi-Tensor unpacking in unpack
• Add Tensor.print
• Add *sum and *mean functions for the various dimension types
• Add map_d2b and map_c2d
• range is now also available as arange
• Deprecate rotation functions and move to PhiFlow
• Improved dataclass attribute detection, add experimental dataclass_getitem

1.8.0

Highlights
