Import error when using torch.utils.bottleneck

I use torch.utils.bottleneck to profile the code.
But I got some import error as follow:

  File "./benchmark/csm/", line 17, in <module>
    from import sc as snc
ImportError: attempted relative import with no known parent package

How can I use ‘torch.utils.bottleneck’ to profile my code without modifying my project code? Because there are a lot of from ...xx import xx as xx in my project.
