ModuleNotFoundError: No module named 'resample2d_cuda'

[TatsuyaOsugi]

Hi,

I faced an issue, 'ModuleNotFoundError: No module named 'resample2d_cuda'.
Do you know how to solve this?

'resample2d_package' folder contains as below.
D:\download\vid2vid\models\flownet2_pytorch\networks\resample2d_package
pycache
init.py
resample2d.py
resample2d_cuda.cc
resample2d_kernel.cu
resample2d_kernel.cuh
setup.py

Following is the cmd command.

This looks like a wrong pytorch version problem. Do you know which version you have installed?

[fniroui]

Having the same issue. Tried pytorch 0.4.1 and 0.4.0.

[CodeBlazer]

Go to the folder:
vid2vid/models/flownet2_pytorch/networks/resample2d_package/

and run the commands:
python3 setup.py build
and
python3 setup.py install

in that order, fixed it for me.

[nwestlake]

I wanted it to work (without this error message or a separate install) for multiple users on an NFS share with users cloning the internal git repo. After running the installers, I copied the ".egg" folders into a directory in NFS (modules/flownet2_pytorch is a symbolic link in the repo):
channelnorm_cuda-0.0.0-py3.5-linux-x86_64.egg
correlation_cuda-0.0.0-py3.5-linux-x86_64.egg
resample2d_cuda-0.0.0-py3.5-linux-x86_64.egg

At run time, I use the following:

I installed flownet2 again and my problem was solved!

[guancheng817]

Go to the folder:
vid2vid/models/flownet2_pytorch/networks/resample2d_package/

and run the commands:
python3 setup.py build
and
python3 setup.py install

in that order, fixed it for me.

thanks, it works well

转到文件夹：
vid2vid / models / flownet2_pytorch / networks / resample2d_package /
并运行命令：
python3 setup.py build
和
python3 setup.py install
按此顺序，为我修好了。

谢谢，它运作良好

I followed your instructions and did the same. But the error is as follows：
ImportError: /home/×××××××/anaconda3/lib/python3.5/site-packages/resample2d_cuda-0.0.0-py3.5-linux-x86_64.egg/resample2d_cuda.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _ZNSt13runtime_errorC2EPKc

[shaldor0315]

maybe you forget to run the commands:
bash install.sh

[jakubLangr]

Hi @shaldor0315 , I got the following issue despite running bash install.sh

python

Any thoughts?

[chinmaychinara91]

I followed all possible steps above but still get the error below:

import resample2d_cuda ImportError: /root/.local/lib/python3.6/site-packages/resample2d_cuda-0.0.0-py3.6-linux-x86_64.egg/resample2d_cuda.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs

I have the following installed:
Python 3.6
Pytorch 1.0.1
CUDA 9.0

Anyone able to solve it ?

[aryanna384]

what files will create after successfully running setup.py build and install?
When I run the above command, I met with:

fatal error C1021: invalid preprocessor command 'warning'
error: command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe' failed with exit status 2

how can I fix it?
