ImportError: cannot import name 'deform_conv_cuda'

When I run the test_Vid4_REDS4_with_GT.py, I got the importError.

`Traceback (most recent call last):
File "/home/EDVR/codes/models/archs/EDVR_arch.py", line 8, in

File "/home/EDVR/codes/models/archs/dcn/deform_conv.py", line 10, in
from . import deform_conv_cuda
ImportError: cannot import name 'deform_conv_cuda'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/EDVR/codes/test_EDVR_REDS_SR_L.py", line 16, in

File "/home/EDVR/codes/models/archs/EDVR_arch.py", line 10, in
raise ImportError('Failed to import DCNv2 module.')
ImportError: Failed to import DCNv2 module.`

My configuration as below:
python 3.5
Pytorch 1.0
GCC 5.4.0
CUDA 8.0

what should I do to handle the error? thanks in advance.

Did you compile the dcn model before running?

Did you compile the dcn model before running?

Thanks for your reply.
I can only find the make.sh in the DCN_v2 code, is there any other pre-steps?

I have the same problem. The issue is that the file codes/models/archs/dcn/deform_conv_cuda is missing.
I run setup.py in codes/models/archs/dcn (both install and build) that maybe should create it, but it didnt help.

[xinntao]

cd ./codes/models/archs/dcn
python setup.py develop

Does this command not create the deform_conv_cuda.xxxxx.so file?

[jkoubele]

cd ./codes/models/archs/dcn
python setup.py develop

Does this command not create the deform_conv_cuda.xxxxx.so file?

That helped, thanks!
(I was running only setup.py install and build, which seemed to be the option after I run setup.py --help, didnt know I can / should run setup.py develop)

[dongxijia]

Thanks a lot! The command python setup.py develop helps !

cd ./codes/models/archs/dcn
python setup.py develop

Does this command not create the deform_conv_cuda.xxxxx.so file?

This helps!
