[Help Request] How can Antares IR support stride size > 1 's Slice operation? #354
Currently we got an issue when we use antares to tune a swin-transformer model, it has a slice operation which's steps can be larger that one.
But from the AntaresIR.md, we noticed that the ir can only support step size equal to 1, for a onnx model I made for antares slice operation test, which same to the onnx operation documentation :
If the steps' data is [1, 1], we can simply get the antares ir code :
output0[N0, N1] = input0[N0 + 1, N1 + 0] where N0 in 1 , N1 in 3
but if the steps' data is [1, 2], it's hard to describe the compute logic :
output0[N0, N1] = input0[N0 + 1, N1 + 0] where N0 in 1 , N1 in {0, 2}
the N1 should jump over the index 2, but I don't find the way to come up with this idea.

So please any suggestion for this case?
