+Profiler Module Introduction.
+
+This module provides Python APIs to enable the profiling of MindSpore neural networks.
+Users can import the mindspore.profiler.Profiler, initialize the Profiler object to start profiling,
+and use Profiler.analyse() to stop profiling and analyse the results.
+To visualize the profiling results, users can open mindspore Web, find the corresponding run
+and click the profile link.
+Now, Profiler supports the AICore operator analysis.
