Import issue: Undefined symbol

When attempting to import Inplace-ABN version 1.1.0, I get the following error:

>>> from inplace_abn import InPlaceABN
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/curttigges/miniconda3/envs/pytorch-dl/lib/python3.7/site-packages/inplace_abn/__init__.py", line 1, in <module>
    from .abn import ABN, InPlaceABN, InPlaceABNSync

I am using CUDA 11.2 and PyTorch 1.8.2. The Inplace-ABN files were compiled with GCC 10.

I update my cuda-10.1 to cuda-10.2, then it works.
