Problem Description

Some TOPI schedules such as depthwise_conv2d_nchw on x86 has no tuning space at all. However since depthwise_conv2d_nchw on CUDA has a tuning space, we still list topi_nn_depthwise_conv2d_nchw as an AutoTVM task. It means depthwise_conv2d_nchw on x86 will be extracted by extract_from_program and "tuned" by AutoTVM. The problem is that this will result in the following record in the history log file:

{"i": ["llvm", "topi_nn_depthwise_conv2d_nchw", [["TENSOR", [1, 192, 28, 28], "float32"], ["TENSOR", [192, 1, 3, 3], "float32"], [2, 2], [1, 1], [1, 1], "float32"], {}, ["depthwise_conv2d_nchw", [1, 192, 28, 28, "float32"], [192, 1, 3, 3, "float32"], [2, 2], [1, 1], [1, 1], "float32"], {"i": 0, "t": "direct", "c": null, "e": []}], "r": ...}

Taking a closer look, we will find an empty config:

{"i": 0, "t": "direct", "c": null, "e": []}

Although it is empty, it is still a valid record and will be loaded when ApplyHistoryBest. The problem is that when building with opt_level=3 on x86, TVM will call AlterOp pass to replace NCHW to NCHWc. During this process, it tries to apply the empty config to the NCHWc schedule template, which results in the following error:

  File "/home/ubuntu/tvm/python/tvm/_ffi/_ctypes/function.py", line 72, in cfun
    rv = local_pyfunc(*pyargs)
  File "/home/ubuntu/tvm/python/tvm/relay/op/nn/_nn.py", line 232, in alter_op_layout_conv2d
    return topi.nn.conv2d_alter_layout(attrs, inputs, tinfos, op)
  File "</usr/local/lib/python3.7/dist-packages/decorator.py:decorator-gen-36>", line 2, in conv2d_alter_layout
  File "/home/ubuntu/tvm/python/tvm/target.py", line 382, in dispatch_func
    return dispatch_dict[k](*args, **kwargs)
  File "/home/ubuntu/tvm/topi/python/topi/x86/conv2d_alter_op.py", line 98, in _alter_conv2d_layout
    ic_bn, oc_bn = cfg["tile_ic"].size[-1], cfg["tile_oc"].size[-1]
  File "/home/ubuntu/tvm/python/tvm/autotvm/task/space.py", line 806, in __getitem__
    return self._entity_map[name]
KeyError: 'tile_ic'

The most obvious case is tuning MoibleNet V2 on x86 which has lots of depthwise conv2d ops, and this problem has been reported by several topics [1][2][3][4]. One workaround suggests users replacing NCHW with NCHWc manually, but it is still confusing.

Solution

This PR proposes a quick fix to this problem by ignoring the records with an empty config when loading from the log file. I choose this solution instead of the following alternatives for reasons. The root solution is actually making up a tuning space for depthwise conv2d on x86 tho.

  • Do not log empty config in callback: We may be still interested in the result of this op with this schedule even it has no config.

  • Use fallback config when the history best config has no entities: Similar to what I proposed but it needs to modify more places.

* [RUNTIME] Remove Extension VTable in favor of Unified Object system. (apache#4578)

Before the unified object protocol, we support pass
additional extension objects around by declaring a type as an extension type.
The old extension mechanism requires the types to register their
constructor and deleter to a VTable and does not enjoy the benefit of the
self-contained deletion property of the new Object system.

This PR upgrades the extension example to make use of the new object system
and removed the old Extension VTable.

Note that the register_extension funtion in the python side continues to work
when the passed argument does not require explicit container copy/deletion,
which covers the current usecases of the extension mechanism.

* [REFACTOR][RUNTIME] Update NDArray use the Unified Object System (apache#4581)

* [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.
