# Script for generating the torch-mlir wheel.
|
|
# ```
|
|
# $ python setup.py bdist_wheel
|
|
# ```
|
|
#
|
|
# It is recommended to build with Ninja and ccache. To do so, set environment
|
|
# variables by prefixing to above invocations:
|
|
# ```
|
|
# CMAKE_GENERATOR=Ninja CMAKE_C_COMPILER_LAUNCHER=ccache CMAKE_CXX_COMPILER_LAUNCHER=ccache
|
|
# ```
|
|
#
|
|
# On CIs, it is often advantageous to re-use/control the CMake build directory.
|
|
# This can be set with the TORCH_MLIR_CMAKE_BUILD_DIR env var.
|
|
# Additionally, the TORCH_MLIR_CMAKE_BUILD_DIR_ALREADY_BUILT env var will
|
|
# prevent this script from attempting to build the directory, and will simply
|
|
# use the (presumed already built) directory as-is.
|
|
#
|
|
# Implementation notes:
|
|
# The contents of the wheel is just the contents of the `python_packages`
|
|
# directory that our CMake build produces. We go through quite a bit of effort
|
|
# on the CMake side to organize that directory already, so we avoid duplicating
|
|
# that here, and just package up its contents.
