Raises queue.Empty on timeout or if the process dies. This method is (so far) only used by TuningProcessPool, where torch._inductor.config entries are being used to populate the timeouts: Arguments: @param result_timeout: Timeout in seconds, defaults to 120.0 or to config.max_autotune_subproc_result_timeout_seconds when called by TuningProcessPool @param graceful_timeout: Timeout in seconds to allow graceful shutdown (SIGTERM is sent after this time). Defaults to 3.0 or to config.max_autotune_subproc_graceful_timeout_seconds @param terminate_timeout: Timeout in seconds after SIGTERM, until we send SIGKILL if the process remains alive. Defaults to 1.0 or to config.max_autotune_subproc_terminate_timeout_seconds.
