URL: https://github.com/apache/tvm/issues/12135
Using this test script:
```python
import tvm
import tempfile
import tvm.script.tir as T
@T.prim_func
def bad_message(
B: T.Buffer[(64), "float32"],
B_pack: T.Buffer[(8, 8), "float32"],
):
with T.block("root"):
for jo in range(8):
for ji in range(8):
B_pack[jo, ji] = B[jo * 8 + ji]
def test_bad_message():
with tempfile.TemporaryDirectory() as tmp:
database = tvm.meta_schedule.database.JSONDatabase(
tmp + "/workload.json", tmp + "/record.json"
)
s = tvm.meta_schedule.tune_tir(
bad_message,
target="llvm -mcpu=znver3 -num-cores=12",
config=tvm.meta_schedule.TuneConfig(
max_trials_global=1000,
max_trials_per_task=1000,
num_trials_per_iter=64,
),
work_dir=tmp,
database=database,
runner=tvm.meta_schedule.runner.LocalRunner(),
)
if __name__ == "__main__":
test_bad_message()
```
gives the following message:
