[Bug]MLIRSparseTensor example can't run

[cmx-Y]

Describe the bug
~/buddy-mlir/examples/MLIRSparseTensor/sparse-tensor-binary.mlir can not run.The same problem will occur when running other files in this folder.

To Reproduce
Just run this command: ~/buddy-mlir/examples/MLIRSparseTensor$ make sparse-tensor-binary-run

Bug Info

./sparse-tensor-binary.mlir:1:22: error: unexpected key: dimLevelType
#SV = #sparse_tensor.encoding<{
                     ^
Error: entry point not found
makefile:96: recipe for target 'sparse-tensor-binary-run' failed
make: *** [sparse-tensor-binary-run] Error 1

Desktop (please complete the following information):

• OS: Ubuntu
• Version: 18.04
• buddy-mlir version : faec06b
• llvm version : 6c59f0e

Solution

#SV = #sparse_tensor.encoding<{
  dimLevelType = [ "compressed" ]
}>

should be replaced with

#SV = #sparse_tensor.encoding<{
  map = (i) -> (i : compressed)
}>

then run ~/buddy-mlir/examples/MLIRSparseTensor$ make sparse-tensor-binary-run, and you will get correct output like this:
