# Error Importing torchvision _C ‘undefined symbol’

## post by drogon on Nov 27, 2019

### Code Block
```
from torchvision import _C as C
ImportError: /usr/lib/python3/dist-packages/torchvision/_C.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN3c107Warning4warnENS_14SourceLocationENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
```

This occurs when trying to use PyTroch’s Fast RCNN.
