根因分析

torch.compile的磁盘缓存目录（默认~/.cache/torch/compile）包含因版本不匹配或写入不完整而导致的陈旧或损坏文件。

English

The on-disk cache directory for torch.compile (default ~/.cache/torch/compile) contains stale or corrupted files due to version mismatch or incomplete writes.

解决方案

  1. Clear the torch.compile cache: rm -rf ~/.cache/torch/compile/
  2. Disable caching entirely: torch._dynamo.config.cache_size_limit = 0
  3. Set a different cache directory: export TORCH_COMPILE_CACHE_DIR=/tmp/torch_cache

无效尝试

常见但无效的做法:

  1. 98% 失败

    The cache is stored in user home directory, not in the package installation; reinstalling doesn't clear it.

  2. 85% 失败

    Debug mode only prints information but doesn't fix the corruption.
