Thanks for sharing all of this—really solid findings. Working with AutoTVM on Windows definitely brings some unique challenges, and your notes highlight the key issues really clearly.
1. **Using 127.0.0.1 instead of 0.0.0.0** That makes sense. `0.0.0.0` can act unexpectedly on Windows, so switching to `127.0.0.1` is a smart workaround for local setups. 2. **Pickle and multiprocessing closures** Yep, this is a common Windows issue since it doesn’t use `fork`. Moving the wrapped function to the top level is the right call—glad to see you already figured that out. 3. **Missing `tar` command** Good tip—Cygwin works, or even Git Bash or WSL. In some cases, using Python’s built-in `tarfile` module could help skip the shell command entirely. 4. **Handling `:` in Windows paths for tar** Adding `--force-local` is a solid workaround when paths include a drive letter. Windows really doesn’t like the colon in CLI tools unless handled this way. 5. **Backslash issues in tar commands** Yeah, replacing `\` with `/` helps when shelling out commands. You might also consider using `pathlib.Path.as_posix()` to keep things cleaner. 6. **Socket error 10048** Pretty typical when sockets don’t release fast enough. Adding specific handling for error 10048 is a good call. 7. **LocalRunner + cpp_rpc** That’s a gotcha for a lot of people. Compiling and manually starting `tvm_rpc.exe` is necessary, and it’s not super obvious. Documenting this better would help a lot. 8. **Tracker/server creation in loops** Definitely inefficient on Windows. Your reuse logic looks like a clean improvement—it’d be great to see something like this upstreamed. 9. **Linker error for `tvm_main`** Seen this too. Annotating or stubbing `tvm_main` is a workable fix for now, but it’d be good to understand why it’s getting pulled in at all during linking. --- [Visit Topic](https://discuss.tvm.apache.org/t/some-questions-about-windows/6900/2) to respond.
