tqchen opened a new issue #7744:
URL: https://github.com/apache/tvm/issues/7744


   see https://github.com/apache/tvm/pull/7743
   
   The recent outrages coulde due to multiple folds of reasons:
   
   - The lack of environment variable updates as in task_rust.sh vs the task_python_docs
   - Change of cargo behavior due to updates? (more likely below)
   - The cargo might caches previous docs build if files does not change (the recent PR of Device refactor triggers a rebuild).
   
   Possible steps:
   - Fix the rust docs build script to make sure it always build correctly
   - Consider some option like force rebuild that always rebuilds the docs(assuming not taking a lot time) regardless of caching

   I believe the key error was:
   > error: couldn't read /workspace/rust/tvm-sys/src/c_runtime_api.rs: No such file or directory (os error 2)
   
   And not the LLVM path because that `LLVM_CONFIG_PATH` warning shows up in previous successful runs.
   
   `c_runtime_api.rs` is normally generated by [bindgen here](https://github.com/apache/tvm/blob/883954ee45b51ca8e2ff96714520a676cd1f8f74/rust/tvm-sys/build.rs#L79). So perhaps that got deleted and bindgen didn't get triggered as part of a semi-stale cache (so didn't trigger `build.rs`)? But I don't have time to dig deeper.
