On the BAD runs:
```
[14:56:21] /home/mbs/github/mbs-tvm/src/relay/ir/transform.cc:135:
AlterOpLayout: Input module:
def @main(%data: Tensor[(1, 3, 10, 10), float32]) -> Tensor[(1, 6, 10, 10),
float32] {
nn.conv2d(%data, meta[relay.Constant][0] /* ty=Tensor[(6, 3, 5, 5),
float32] */, padding=[2, 2, 2, 2], kernel_size=[5, 5], out_dtype="float32") /*
ty=Tensor[(1, 6, 10, 10), float32] */
}
[14:56:21] /home/mbs/github/mbs-tvm/src/relay/ir/transform.cc:159:
AlterOpLayout: Output module:
def @main(%data: Tensor[(1, 3, 10, 10), float32]) -> Tensor[(1, 6, 10, 10),
float32] {
%0 = layout_transform(%data, src_layout="NCHW", dst_layout="NCHW16c");
%1 = nn.conv2d(%0, meta[relay.Constant][0] /* ty=Tensor[(6, 3, 5, 5),
float32] */, padding=[2, 2, 2, 2], kernel_size=[5, 5], data_layout="NCHW16c",
out_dtype="float32");
layout_transform(%1, src_layout="NCHW16c", dst_layout="NCHW")
}
```
I can't find any matching rewrite on the GOOD runs -- they're all of the
form:
```
[14:53:31] /home/mbs/github/mbs-tvm/src/relay/ir/transform.cc:135:
AlterOpLayout: Input module:
def @main(%data: Tensor[(1, 3, 10, 10), float32]) -> Tensor[(1, 6, 10, 10),
float32] {
nn.conv2d(%data, meta[relay.Constant][0] /* ty=Tensor[(6, 3, 5, 5),
float32] */, padding=[2, 2, 2, 2], kernel_size=[5, 5], out_dtype="float32") /*
ty=Tensor[(1, 6, 10, 10), float32] */
}
[14:53:31] /home/mbs/github/mbs-tvm/src/relay/ir/transform.cc:159:
AlterOpLayout: Output module:
def @main(%data: Tensor[(1, 3, 10, 10), float32]) -> Tensor[(1, 6, 10, 10),
float32] {
%0 = layout_transform(%data, src_layout="NCHW", dst_layout="NCHW3c");
%1 = layout_transform(meta[relay.Constant][0] /* ty=Tensor[(6, 3, 5, 5),
float32] */, src_layout="OIHW", dst_layout="OIHW3i3o");
%2 = nn.contrib_conv2d_NCHWc(%0, %1, padding=[2, 2, 2, 2], channels=6,
kernel_size=[5, 5], data_layout="NCHW3c", kernel_layout="OIHW3i3o",
out_layout="NCHW3c", out_dtype="float32");
layout_transform(%2, src_layout="NCHW3c", dst_layout="NCHW")
}
```
Eh?
