I've tried using **faulthandler** to locate the error: ```python #code.py import faulthandler faulthandler.enable() import tvm ``` After running `python -X faulthandler code.py`, I got messages below: ``` Fatal Python error: Segmentation fault Current thread 0x00007f01d5705280 (most recent call first): File "/root/tvm-18/python/tvm/_ffi/_ctypes/packed_func.py", line 235 in __call__ File "/root/tvm-18/python/tvm/target/tag.py", line 33 in list_tags File "/root/tvm-18/python/tvm/target/tag.py", line 81 in <module> File "<frozen importlib._bootstrap>", line 219 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 843 in exec_module File "<frozen importlib._bootstrap>", line 671 in _load_unlocked File "<frozen importlib._bootstrap>", line 975 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 991 in _find_and_load File "/root/tvm-18/python/tvm/target/__init__.py", line 77 in <module> File "<frozen importlib._bootstrap>", line 219 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 843 in exec_module File "<frozen importlib._bootstrap>", line 671 in _load_unlocked File "<frozen importlib._bootstrap>", line 975 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 991 in _find_and_load File "<frozen importlib._bootstrap>", line 219 in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1042 in _handle_fromlist File "/root/tvm-18/python/tvm/__init__.py", line 58 in <module> File "<frozen importlib._bootstrap>", line 219 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 843 in exec_module File "<frozen importlib._bootstrap>", line 671 in _load_unlocked File "<frozen importlib._bootstrap>", line 975 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 991 in _find_and_load File "code.py", line 3 in <module> Segmentation fault (core dumped) ``` There seems to be something wrong with the fuction in `tvm/python/tvm/_ffi/_ctypes/packed_func.py` as mentioned above while executing in my Environment. ### Environment * Ubuntu 20.04.6 LTS * Docker image of [12.4.1-cudnn-devel-ubuntu20.04](https://hub.docker.com/layers/nvidia/cuda/12.4.1-cudnn-devel-ubuntu20.04/images/sha256-827ce25f7036c5a9c76a68d68c1f49295baef1c7e56157a8cd2495a6e40de2aa?context=explore) * LLVM-18.1.8 prebuild version for Ubuntu 18.04: (download from [here](https://github.com/llvm/llvm-project/releases/download/llvmorg-18.1.8/clang+llvm-18.1.8-x86_64-linux-gnu-ubuntu-18.04.tar.xz)) * Use Apache TVM v0.18.0 Release version, and `config.cmake` appending settings are: `set(USE_CUDA ON)`, `set(USE_CUBLAS ON)`, `set(USE_CUDNN ON)`, `set(USE_LLVM "\<path-to-llvm-config\> --ignore-libllvm --link-static")` and `set(HIDE_PRIVATE_SYMBOLS ON)` * Correctly set `TVM_HOME` and `PYTHONPATH`, use conda venv and python 3.8. ### Steps to reproduce ``` python -c "import tvm" ``` ### Triage * needs-triage * core:ffi -- This is an automated message from the Apache Git Service.
