Error when importing resample2d_cuda

[mhq6634]

I have followed the instruction to build Gaussian Sampling CUDA package:

• cd ./StructureFlow/resample2d_package
• python setup.py install --user

However, I get below error:

File "/data/abc/StructureFlow/src/resample2d.py", line 4, in import resample2d_cuda ImportError: /ldap_home/abc/.local/lib/python3.7/site-packages/resample2d_cuda-0.0.0-py3.7-linux-x86_64.egg/resample2d_cuda.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZN6caffe26detail37_typeMetaDataInstance_preallocated_32E

My environment:

• CUDA: 10.1 (which is something I cannot change on the server and I doubt this may be the cause, but I am not sure)
• Pytorch: 1.0.1
• Python: 3.7

Could anyone give me some advice? Or anyone has tried it successfully on CUDA 10.1?

yes，CUDA10.1 is ok，my python is 3.6.8 ，you can try it.------------------ 原始邮件 ------------------ 发件人: "Huiqi"notifications@github.com 发送时间: 2019年12月20日(星期五) 下午5:59 收件人: "RenYurui/StructureFlow"StructureFlow@noreply.github.com; 抄送: "Subscribed"subscribed@noreply.github.com; 主题: [RenYurui/StructureFlow] Error when importing resample2d_cuda (#18)

I'm not particularly sure about the reason for this problem. But here is some information which may be useful. My pytorch version is 1.0.0. (Please double check you pytorch version, cause i think this may be the main reason.) You may need to change the "nvcc_args" in the setup.py if you do not use "arch sm_60"

Thank you for your reply. May I know your pytorch version as well?

I met similar problem. I found that the Pytorch version must be 1.0.0 in the compiling. In the first, I used version 1.0.1 and the problem happened. Then I used 1.0.0 to compile, the problem disappeared. The resulting package can also be used in 1.0.1.
