Undefined symbol when import lltm cpp extension

C++
7

I’m facing the same problem when running this sample: https://github.com/NVIDIA/retinanet-examples

I build my pytorch from source, and have set the _GLIBCXX_USE_CXX11_ABI to be False. Then I built the extension, but when running it, this error occurs:

Traceback (most recent call last):
  File "/ssd2/exec/xiaoyunlong/code/retinanet-examples/retinanet/main.py", line 10, in <module>
    from retinanet import infer, train, utils
  File "/ssd2/exec/xiaoyunlong/anaconda3/lib/python3.7/site-packages/retinanet/infer.py", line 13, in <module>
    from .model import Model
  File "/ssd2/exec/xiaoyunlong/anaconda3/lib/python3.7/site-packages/retinanet/model.py", line 8, in <module>
    from ._C import Engine
ImportError: /ssd2/exec/xiaoyunlong/anaconda3/lib/python3.7/site-packages/retinanet/_C.so: undefined symbol: _ZN2cv8fastFreeEPv

I have checked the _GLIBCXX_USE_CXX11_ABI by torch._C._GLIBCXX_USE_CXX11_ABI and it outputs False.

Am I missing something? or did something wrong?
