      * [REFACTOR][PY] tvm._ffi
      
      - Remove from __future__ import absolute_import in the related files as they are no longer needed if the code only runs in python3
      - Remove reverse dependency of _ctypes _cython to object_generic.
      - function.py -> packed_func.py
      - Function -> PackedFunc
      - all registry related logics goes to tvm._ffi.registry
      - Use absolute references for FFI related calls.
        - tvm._ffi.register_object
        - tvm._ffi.register_func
        - tvm._ffi.get_global_func
      
      * Move get global func to the ffi side

    • [REFACTOR][RUNTIME] Update NDArray use the Unified Object System (#4581) · 55bd786f
      * [REFACTOR][RUNTIME] Move NDArray to Object System.
      
      Previously NDArray has its own object reference counting mechanism.
      This PR migrates NDArray to the unified object protocol.
      
      The calling convention of NDArray remained intact.
      That means NDArray still has its own type_code and
      its handle is still DLTensor compatible.
      
      In order to do so, this PR added a few minimum runtime type
      detection in TVMArgValue and RetValue only when the corresponding
      type is a base type(ObjectRef) that could also refer to NDArray.
      
      This means that even if we return a base reference object ObjectRef
      which refers to the NDArray. The type_code will still be translated
      correctly as kNDArrayContainer.
      If we assign a non-base type(say Expr) that we know is not compatible
      with NDArray during compile time, no runtime type detection will be performed.
      
      This PR also adopts the object protocol for NDArray sub-classing and
      removed the legacy NDArray subclass protocol.
      Examples in apps/extension are now updated to reflect that.
      
      Making NDArray as an Object brings all the benefits of the object system.
      For example, we can now use the Array container to store NDArrays.

    • [REFACTOR][NODE][RUNTIME] Move Node to the new Object protocol. (#4161) · 7895adb2
      * [REFACTOR][NODE][RUNTIME] Move Node to the new Object protocol.
      
      This PR removes the original node system, and make node as a subclass of Object.
      This is a major refactor towards a better unified runtime object system.
      
      List of changes in the refactor:
      
      - We now hide data_ field, use Downcast explicitly to get a sub-class object.
      - Removed the node system FFI in python.
      - Removed the node C API, instead use PackedFunc for list and get attrs.
      - Change relay::Op::set_attr_type_key(attr_key_name) to relay::Op::set_attr_type<AttrType>().
        - This change was necessary because of the new Object registration mechanism.
        - Subsequent changes to the op registrations
        - The change revealed a few previous problems that is now fixed.
      - Patched up a few missing node type registration.
        - Now we will raise an error if we register object that is not registered.
      - The original node.h and container.h are kept in the same location.
      - Calling convention: kObjectHandle now equals the old kNodeHandle, kNodeHandle is removed.
      - IRFunctor now dispatches on ObjectRef.
      - Update to the new type checking API: is_type, derived_from are replaced by IsInstance.
      - Removed .hash member function, instead use C++ convention hasher functors.

    • [RUNTIME] Refactor object python FFI to new protocol. (#4128) · 02c1e117
      * [RUNTIME] Refactor object python FFI to new protocol.
      
      This is a pre-req to bring the Node system under object protocol.
      Most of the code reflects the current code in the Node system.
      
      - Use new instead of init so subclass can define their own constructors
      - Allow register via name, besides type idnex
      - Introduce necessary runtime C API functions
      - Refactored Tensor and Datatype to directly use constructor.
