Remove deprecated `dpctl.tensor` submodule by ndgrigorian · Pull Request #2245 · IntelPython/dpctl

ndgrigorian · 2026-02-05T04:57:00Z

This PR removes the dpctl.tensor submodule, as it is migrated to dpnp as dpnp.tensor

This change makes dpctl a much smaller, lighter-weight package, with no built-in tensor capabilities. The memory sub-module and order_manager remain to support tensor-like extensions, but dpctl will focus on device management and providing a Python interface to SYCL implementations

in C, Cython, or pybind11 to access `dpctl` objects representing SYCL devices, queues, memory, and tensors.

This should probably be removed as well

Dpctl includes a reference implementation for :array_api:array API specification <> using DPC++ and USM memory allocation in the :class:dpctl.tensor sub-module. The :class:dpctl.tensor sub-module provides an N-dimensional array Python object :class:dpctl.tensor.usm_ndarray and a growing implementation of :array_api:array API specification <> compliant operations on instances of the array class.
