NumPy Support

Note

This section is a work in progress. It does not reflect the capabilities provided in the latest version of DaCe.

The Data-Centric Python-Frontend currently supports a limited subset of NumPy:

• Python unary and binary operations among NumPy arrays, constants, and symbols. Binary operations mainly work between arrays that have the same shape. Operations between arrays of size 1 and arrays of any size are also supported.

• Array creation routines ndarray, eye

• Array manipulation routine transpose

• Math routines eye, exp, sin, cos, sqrt, log, conj, real, imag (only the input positional argument supported)

• Reduction routines sum, mean, amax, amin, argmax, argmin (input positional and axis keyword arguments supported)

• Type conversion routines, e.g., int32, complex64, etc.

• All built-in universal functions (ufunc):

  • Ufunc call with optional out, where, and dtype keyword arguments. Standard NumPy broadcasting rules are applied.

  • Ufunc reduce method with optional out, keepdims, axis, and initial keyword arguments.

  • Ufunc accumulate method with optional out, axis keyword arguments.

  • Ufunc outer method with optional out, where, and dtype keyword arguments.
