vfdff opened a new issue, #17692: URL: https://github.com/apache/tvm/issues/17692
### Expected behavior When I repeatedly try to run **matmul_ansor.py** , we 'll get different schedule results every time showed in MeasureResult **No: 1 ~ No: 10**, so I expected the following **TIR dump** will matched the above best schedule result, .i.e I expect they are different. [matmul_ansor.py.txt](https://github.com/user-attachments/files/19020167/matmul_ansor.py.txt) ### Actual behavior The **Lowered TIR** always get same result on my Arm64 target (), ie: dump with **print(tvm.lower(sch, args, simple_mode=True))** ### Environment (172) Any environment details, such as: Operating System, TVM version > (/py311-tts) root@998ee80b761b:/home/zhongyunde/source/test/ansor# python -c "import tvm; print(tvm.__version__)" 0.19.dev0 > (/py311-tts) root@998ee80b761b:/home/zhongyunde/source/test/ansor# cat /etc/os-release PRETTY_NAME="Ubuntu 22.04.1 LTS" ### Steps to reproduce The script is get from https://tvm.hyper.ai/docs/tutorial/ops_AutoScheduling then repeatedly run: **python matmul_ansor.py** For example, I get the 2 logs and compare them, we'll see the part of **Lowered TIR** is same, but the prior schedule results are different.  ### Triage Please refer to the list of label tags [here](https://github.com/apache/tvm/wiki/Issue-Triage-Labels) to find the relevant tags and add them below in a bullet format (example below). * needs-triage -- This is an automated message from the Apache Git Service.
