试过更改.brashrc的CUDA的环境变量，但是不行，这个问题要怎么解决?

同问+1

建议检查以下CUDA_HOME，以及默认cuda路径的版本是否与pytorch的一致。

[MhLiao]

Make sure your CUDA path of $CUDA_HOME is the same version as your CUDA in PyTorch by the command of echo $CUDA_HOME. If not, you need to change the $CUDA_HOME by export CUDA_HOME=path-of-another-version or re-install PyTorch with the same CUDA version as in CUDA_HOME.

@MhLiao 能否在python2下编译呢？

[Tian14267]

请问楼主问题解决了吗？我的pytorch==1.0.0 cuda == 9.0。遇到跟你一样的问题。请问怎么解决啊。 @ @MTCai @MhLiao @suntianlei2019102967

遇到了同样的问题，惆怅中

[fujingling]

我是编译通过，运行eval.py时报错DB/assets/ops/dcn/deform_conv_cuda.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs

@fujingling @Tian14267 请问你们编译错误的问题是怎么解决的啊？
