Best Practice in development

Git Practice

• When you develop on a branch, use rebase instead of merge because merge may flood the actual new commits on main branch.

Debug Practice

Debug from python script into c++ code in vs code (remote ssh)

Steps

1. Pick PR: https://github.com/intel/torch-xpu-ops/pull/1671 at the time being.
2. Build debug version of pytorch:
   • export DEBUG=1
   • export BUILD_SEPARATE_OPS=ON (https://github.com/intel/torch-xpu-ops/blob/main/CMakeLists.txt#L92)
   • python setup.py develop 2>&1 | tee build.log
3. Mixed Language Debugging (Python and C++) or Python C++ Debugger, both work.
4. Fix gdb attach permission issue: Superuser access is required to attach to a process. Attaching as superuser can potentially harm your computer. Do you want to continue? [y/N]
   echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
