So the 2x2 is actually encoding 2 transforms: one is the producer's change, and the other is the consumer's (expected) change. For a weird example, before the change: `(A) conv_NCHW -> (B) conv_NCHW` after the change: `(A') conv_NCHW2c -> (B') conv_NCHW4c`. Suppose we are rewriting Node B. Then the producer's change will be NCHW->NCHW2c, and the consumer's expected change will be NCHW->NCHW4c. There are 4 layouts, hence 2x2 combinations. -- This is an automated message from the Apache Git Service.
