Mmdetection: undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs

[bluoluo]

当我在终端里

python tools/test.py configs/mask_rcnn_x101_64x4d_fpn_1x.py checkpoints/mask_rcnn_x101_64x4d_fpn_1x_20181218-cb159987.pth --out results.pkl --eval bbox segm

就出现

ImportError: /home/bluo/mmdetection/mmdet/ops/dcn/deform_conv_cuda.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs

错误

请问给如何解决？

ubuntu18.04
conda新建的环境环境：Python3.6.8、pytorch1.0.1

When I use anaconda to create a virtual environment of mmdetection, and the settings are following:
First, I have a cuda10.0 in /usr/local/cuda-10.0.
then the mmdetection environment used pytorch1.2 cudatoolkit10.0, but the driver of GPU is 418.
the problem of undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs will occur
but I used pytorch1.3, cudatoolkit10.1 and the CUDA_HOME=/usr/local/cuda-10.1.
the code can run.
I guess the reason for the problem is not matching in some librarys 's version.

I meet this problem too. I solve it by installing pytorch from pytorch official channel, instead of mirror such as tsinghua and alibaba.
