This is a long time ago, it seems that the environment variable problem, or compile problem, I only changed the two places

sorry but now I'm also troubled by this issue:
`>>> from mmdet.models import build_detector

I check the code of mmdet/ops/dcn/functions/deform_conv.py,and
from .. import deform_conv_cuda in this file ,I can't find a source of deform_conv_cuda.
This problem has troubled me for three days, and I can not debug through the demo.Could you give some suggestions?thanks.

Answer 5 · 2019-04-19T20:11:43.000Z

you can simply change the folder name of mmdet to other names. Since the deform_conv_cuda should be referred to the one in the path /usr/local/lib/python3.5/dist-packages/mmdet-0.5.7+unknown-py3.5.egg/mmdet/ops/dcn/deform_conv_cuda.cpython-35m-x86_64-linux-gnu.so, but here the same folder "mmdet" in your current project direction confused the system. To me, just change that folder name solved the problems well.

I changed the file name of mmdet to mmdet1, but the same error still occurs.

hi，good morning，Do you have this problem?

Answer 13 · 2019-07-01T15:42:17.000Z

Hi, did you solve the problem?

Answer 14 · 2019-07-15T01:02:36.000Z

check your LD_LIBRARY_PATH, it should point to /usr/local/cuda/lib64 to check LD_LIBRARY_PATH use echo $LD_LIBRARY_PATH if not set to this location manually update in .bashrc. Add this line export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH, if using pycharm add path to run config. This should solve this issue

Answer 17 · 2019-07-26T03:30:53.000Z

Anyone can give me some advice?

Answer 18 · 2019-07-26T03:54:12.000Z

@wdd233 这是由于mmdetection版本问题, 之前的版本安装方法是python setup.py develop, 再./compile.sh, 新的版本里去掉了这种方式, 改为

Implement all extension building in main setup.py.

因此这个问题有两种解决方法:

仍然使用之前的版本, 执行./compile.sh
拉取新版本, 重新编译(直接执行python setup.py develop)

Answer 19 · 2019-09-02T08:42:51.000Z

If someone is working on colab, running the following has solved this issue for me:

!python setup.py develop

Answer 20 · 2020-06-17T02:19:07.000Z

I am getting the same error on Google Colab. Did the

compile.sh
!python setup.py develop
!python3 setup.py develop

All the above commands ran successfully, but the error didn't resolve?

您好！
请问拷给的项目文件是整个mmdetection文件夹里的所有子文件吗？

Answer 22 · 2020-07-04T19:41:43.000Z

Steps to resolve the problem:

Use the correct mmdetection source code https://github.com/open-mmlab/mmdetection. There are many versions of mmdetection on github, and I was using the wrong one.
Make sure that GPU runtime is selected on Google colab.
Verify the output of compile.sh. If it contains something related to .so file generation at the end of the output, then you are good.
Run the setup.py develop command.

These steps should resolve the issue.

yes, i believe this problem can be solved after follow your steps, but i can't find the "compile.sh" file, would u mind tell me where can i get this file?

Answer 24 · 2021-01-05T03:39:31.000Z

I try another ways.
In the tutorial, setup the docker ,and from docker copy the /mmdection to the host.I guess maybe something wrong happen when we setup the mmdection leads to lack of some files.
sudo docker container cp -a d2dec54610bd:/mmdetection /home/usr
