      Explores the cache to return the latest cached file for a given revision if found.
  
      This function will not raise any exception if the file in not cached.
  
      Args:
          cache_dir (`str` or `os.PathLike`):
              The folder where the cached files lie.
          repo_id (`str`):
              The ID of the repo on huggingface.co.
          filename (`str`):
              The filename to look for inside `repo_id`.
          revision (`str`, *optional*):
              The specific model version to use. Will default to `"main"` if it's not provided and no `commit_hash` is
              provided either.
          repo_type (`str`, *optional*):
              The type of the repository. Will default to `"model"`.
  
      Returns:
          `Optional[str]` or `_CACHED_NO_EXIST`:
              Will return `None` if the file was not cached. Otherwise:
              - The exact path to the cached file if it's found in the cache
              - A special value `_CACHED_NO_EXIST` if the file does not exist at the given commit hash and this fact was
                cached.
  
      Example:
  
      ```python
      from huggingface_hub import try_to_load_from_cache, _CACHED_NO_EXIST
  
      filepath = try_to_load_from_cache()
      if isinstance(filepath, str):

          # non-existence of file is cached
          ...
