the buffer.getType() is `memref<16515072xf16, strided<[1], offset: 4128768>>` while the memrefType is `memref<16515072xf16>`. CastOp can't convert between the two type.
Maybe we can use:
```
%alloc = memref.alloc() : memref<16515072xf16>
memref.copy %collapse_shape, %alloc : memref<16515072xf16, strided<[1], offset: 4128768>> to memref<16515072xf16>
```
How should I modify the code to do this? @matthias-springer
