Validating the apache-tvm wheel in a minimal environment (no torch,
scipy, cloudpickle, or tornado installed) produced 33 pytest collection
errors from module-level imports of optional packages. Add
pytest.importorskip guards so these modules are reported as skipped
instead of erroring during collection.
Indirect import chains guarded:
- tvm.topi.testing imports scipy
- tvm.s_tir.meta_schedule.testing.local_rpc (tvm.rpc.tracker) requires
tornado
- tvm.s_tir.dlight.benchmark imports cloudpickle
Also remove a stray pre-license-header `import pytest` in
test_runtime_builtin_paged_attention_kv_cache_flashinfer.py.
