# `tile_primitive` defines Python Op classes (`Zero(UnaryOp)`, etc.) whose
|
|
# class bodies call `Op.get("tirx.<name>")` at class-definition time, which
|
|
# requires the compiler-side FFI. Load it lazily so that
|
|
# `tvm.tirx.operator.intrinsics._common` (pure data) and other runtime-safe
|
|
# submodules can be imported under `TVM_USE_RUNTIME_LIB=1`, matching apache's

|
# discipline for `tvm.tirx`.

# machinery does `getattr(self, 'tile_primitive')` to see if the submodule

|
# is already loaded, which goes back through this __getattr__. Use
|
|
# importlib.import_module to bypass attribute lookup; it sets the attribute
|
|
# on the parent package as a side effect, so subsequent lookups go through
|
|
# the normal attribute path, not this __getattr__.
