Hello,

I am linking cutlass with tvm but I have many problem I am running [https://github.com/apache/tvm/blob/v0.12.dev0/tests/python/contrib/test\_cutlass.py](https://github.com/apache/tvm/blob/v0.12.dev0/tests/python/contrib/test_cutlass.py)

first problem, I can’t run _**has\_cutlass()**_ in **tvm.contrib.cutlass.build** because they can’t not find “relay.ext.cutlass.create\_c\_source\_module”

second problem, if I give kind=“cutlass” to tvm.Target.target, it makes error

how can I link cutlass in tvm? I am using tvm 12.0 dev0 and llvm 15.0.6 and when I install tvm I turn on USE\_CTLASS and USE\_CUDA. I am also using gpu nvidia titan xp(sm61)
