ok i found the original design discussion [here ](https://github.com/apache/incubator-mxnet/pull/12456/files#r218632768) > The fundamental problem here is that if we create multiple executors in the same thread (e.g., in the main thread), these executors will share the same temporary resources, which leads to race condition when these executors are used in different threads. To fix this problem, here we avoid creating executors when we create predictors in the main thread. The executors are actually created when the predictor is used in the worker thread for the first time. As long as the executor is always used in this worker thread, there won't be race condition. by zheng-da So i guess a better approach is to lock https://github.com/apache/incubator-mxnet/blob/v1.x/src/c_api/c_predict_api.cc#L75 -- This is an automated message from the Apache Git Service.
