This release splits out the TACO binary into a separate package tensora-taco. This package is optional, making the TACO code generator optional. The native Tensora code generator is still included and used by default. TACO can be still be used as an alternative code generator if the tensora[taco] extra is installed.

Also, these other changes:

  • The signature of tensor_method was changed so that the output_format and input_formats were combined into one formats dictionary
  • Renamed PureTensorMethod to TensorMethod to reflect the decision that mutable assignments will never be supported in Tensora
  • Most of the attributes on TensorMethod were made private
  • Cache on a parsed Problem, instead of on the string versions of assignments and formats
  • Raise a nice exception on TensorMethod when trying to broadcast to target indexes because there is no way for the dimensions of those indexes to be known. Generating such kernels via the tensora CLI is still permitted.
  • Raise a nice exception when a tensor and and index have the same name in an assignment
  • Remove Tensor.from_scalar; you could always use Tensora.from_lol
  • Do not cast the result of a vector inner product a @ b to a Python scalar; leave it as a scalar Tensor
