Good news! I solved the problem! Try this method: excute Now you can excute I hope it will be helpful to you! |

thank you! i use the similar methods, and also get lots of warnings. at last, it prints 'Finished processing dependencies for mmdet==1.1.0+365c930'
But can you run the demo?
when i run the demo, it prints 'ImportError: ***/mmdetection/mmdet/ops/dcn/deform_conv_cuda.cpython-37m-x86_64-linux-gnu.so: undefined symbol: atexit', and you?
yes, i am chinese too, can we add qq friend or wechat? my qq number can be seen in my email site.

Good news! I solved the problem! Try this method:
https://stackoverflow.com/questions/47512182/cannot-find-lfftw3-omp-error-when-compiling-a-third-party-package-how-to-lin
excute ld -lc --verbose and get path1 which shows 'scueeded'
and excute ln -s path1 path2
My path2 is '/home/computer/anaconda3/compiler_compat'
Now you can excute python setup.py develop
It will take a long time(maybe 10 mins) and maybe you will get lots of warnings.
I hope it will be helpful to you!
I guees you are Chinese.If so, we can communicate in Chinese.

i install mmdetection in conda virtual environment with 'python setup.py develop'.
but it tells me, ''ImportError: ***/miniconda3/envs/open-mmlab/lib/python3.7/site-packages/torch/../../../libstdc++.so.6: version `CXXABI_1.3.11' not found (required by /DB/rhome/yuhangzhou/miniconda3/envs/open-mmlab/lib/python3.7/site-packages/torch/lib/libtorch_python.so)'',
then i remove original libstdc++.so.6, and run ''ln -s libstdc++.so.6.0.26 libstdc++.so.6''
after that, i run '''python setup.py develop' again,
it prints:

ps: in my conda virtual environmen, i used ''conda install -c psi4 gcc-5'', after that, when i run 'gcc -v' or 'g++ -v',
