jdnie / addernetcuda Goto Github PK

Hello, I have a question. It seems that you set your code running on just one gpu, and how can I run via multi gpu?

Hi @jdnie

Your code is impressive. However, when I try to use the cuda and run "python setup.py install", there are a lot of error.

What is the reason? I follow your instruction to use pytorch 1.2.0 and torchvision 0.4.0.

used your training code, the accuracy is about 50%，but the paper's accuracy has achieved 90%,could you please tell me why?

I have download the whole files AdderNetCuda, and then I put it on cloud platform.
cd unoptimized
python setup.py install
python test.py

Question is :

• I want to know the solution to the problem "Unable to import CUDA unoptimized kernels"

The environment is :
NVIDIA GeForce RTX 3080, 1

The version of torch and torchvision are :
torch 1.10.0+cu111
torchvision 0.11.0+cu111

However, I cannot get the results of method using cuda. The program gives me

• Unable to import CUDA unoptimized kernels

I followed the instructions in the readme file to run the code and getting the following error. Am I doing something wrong?

File "/content/utils.py", line 39, in accuracy
correct_k = correct[:k].view(-1).float().sum(0, keepdim=True)
RuntimeError: view size is not compatible with input tensor's size and stride (at least one dimension spans across two contiguous subspaces). Use .reshape(...) instead.

I have not made any changes to the code.
