• 版本、环境信息：   PaddlePaddle版本：1.8.1，python3.6环境，linux 执行paddle的时候，遇到一个特别奇怪的错误，只运行执行函数A，结果正常，如果在A后再运行B的话，就会报错了。A和B单独执行都正常，如果 我用在调试模式下进行，这整个流程都没问题。所以问题到底是什么呢？？？

  2020-07-01 19:16:49,783-WARNING: variable file [ ./script/model_files/simnet_bow_pairwise_pretrained_model/model ./script/model_files/simnet_bow_pairwise_pretrained_model/info.yml ] not used OMP: Error #15: Initializing libomp.so, but found libiomp5.so already initialized. OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.
