 Q4. While converting .pb file to MindSpore script, what may be the cause of error code 1000001 with ensuring `model_file`, `shape`, `iput_nodes` and `output_nodes` set right and third party requirements installed correctly?
 > Answer: Make sure that the TensorFlow version to generate .pb file is no higher than that to convert .pb file, avoiding the conflict which caused by using low version TensorFlow to parse .pb file generated by high version one.
 
+Q5. What should I do to deal with Exception `[ERROR] MINDCONVERTER: [BaseConverterError] code: 0000000, msg: {python_home}/lib/libgomp.so.1: cannot allocate memory in static TLS block`?
+
+> Answer: In most cases, the problem is caused by environment variable exported incorrectly. Please set `export LD_PRELOAD={python_home}/lib/libgomp.so.1.0.0`, then try to rerun MindConverter.

 > 答：请检查生成该.pb文件所使用的TensorFlow版本不高于用于转换时安装的TensorFlow版本，避免由于旧版本TensorFlow无法解析新版本生成的.pb文件，而导致的模型文件解析失败。
