"""Post-install checks for a built TVM wheel.
|
|
|
|
These live in ``tests/python/all-platform-minimal-test`` so the standard suite and
|
|
the cibuildwheel ``test-command`` run a single pytest invocation. The assertions
|
|
here are wheel-specific things the rest of the suite cannot check -- that LLVM is
|
|
enabled (the other LLVM test merely *skips* when LLVM is absent) and that the CUDA
|
|
runtime library got bundled -- so each is gated behind a ``TVM_WHEEL_EXPECT_*`` env
|
|
var and SKIPS unless that var is set. cibuildwheel sets the vars (see
|
|
``CIBW_TEST_ENVIRONMENT`` in ``.github/actions/build-wheel-for-publish``); ordinary
|
|
source-build CI (e.g. ``main.yml``) leaves them unset, so these tests skip there and
|
|
never fail a non-wheel / non-LLVM / non-CUDA build.
