Support mixed precision training with NVIDIA apex

It would be great if the correlation cuda kernel supported half precision operations, which would enable us to use the library for mixed precision training with NVIDIA Apex. #

Output shape does not reflect dilation_patch parameter.

The dilation_patch parameter seems not correctly interpreted:

>>> import torch
>>> from spatial_correlation_sampler import SpatialCorrelationSampler
>>> x = torch.ones(1, 1, 10, 10)
>>> SpatialCorrelationSampler(patch_size=4, dilation_patch=1)(x, x).shape
torch.Size([1, 5, 5, 10, 10])
>>> SpatialCorrelationSampler(patch_size=5, dilation_patch=2)(x, x).shape
torch.Size([1, 5, 5, 10, 10])
>>> SpatialCorrelationSampler(patch_size=5, dilation_patch=3)(x, x).shape
torch.Size([1, 5, 5, 10, 10])

Regardless of the stepping within the patch the output shape is just the same.

python benchmark.py try to allocate cuda memory 9177984325.83 GiB

when I try to run benchmark.py, it raise an error says that
RuntimeError: CUDA out of memory. Tried to allocate 9177984325.83 GiB (GPU 0; 5.93 GiB total capacity; 78.25 MiB already allocated; 4.44 GiB free; 0 bytes cached) (malloc at /pytorch/aten/src/THC/THCCachingAllocator.cpp:231)

here is my environments:

Is something wrong? thanks a lot.

Is it possible to use the module for 1d correlation only

Hi, thanks for the package!
Is it possible to use this module to perform 1D correlation?
By saying 1d correlation, I mean to do correlation only along X direction, or Y direction, or certain customized direction (e.g. along epipolar line) to save some computation.
if not, would you mind offer some hints to modify the code for that?

Link is not available

Thank you for your great work! But the link below is not available now. I'll be grateful if you correct this error.

The backward pass of NVIDIA is not entirely correct when stride1 > 1 and kernel_size > 1, because not everything is computed, see here.

This is the original link address:
https://github.com/NVIDIA/flownet2-pytorch/blob/master/networks/correlation_package/src/correlation_cuda_kernel.cu#L120

The padding parameter

I don't understand that padding operation influences both input1 and input2...

Why don't you just padding the input2?

for instance, if I have a pixel at the left-top position in input1, so the corresponding pixel in input2 is also at the left-top position, and the padding to the input2 is enough if I want to do the correlation operation around the pixel in input2. So why do you padding the input1 and end up enlarging the outH and outW?

Error running module on GPU

Hi Clement, I have been using your spatial-correlation-sampler. When I run python grad_check cpu it returns 'ok' but with backend option set as cuda, I get the following error:

I also tried to pass some tensors into the module in the console. Calling forward and backward seems to be fine as long as computation is on cpu. The module crashes once I put the same tensor on GPU.

Code is running on Ubuntu 14.04. I am using anaconda python 3.6.5. My pytorch version is 0.4.1. And I am using CUDA 9.0.

It is worth mentioning that I had trouble installing the code, as I later discovered that nvcc is using gcc-6.0 which is incompatible with my CUDA 9.0 and I redirected the softlink to gcc-4.9. By doing this I am able to compile and install. Not sure if it is related to this crash.

Please let me know what you think. Thank you!

patch_dilation seems problemetic

Hi @ClementPinard , I find something wrong when I use patch_dilation>1. The output shape looks good to me, but the value is weird to me. Here is an example:

import torch
from spatial_correlation_sampler import SpatialCorrelationSampler

torch.manual_seed(0)

device = "cuda"
batch_size =1 
channel =1
H = 10
W = 10
dtype = torch.float32

B = batch_size
kernel_size = 1
patch = 3
stride = 1
pad = 0
patch_dilation = 2

input1 = torch.randint(1,4,(batch_size,channel,H,W),dtype=dtype,device=device,requires_grad=True)
input2 = torch.randint_like(input1,1,4).requires_grad_(True)

correlation_sampler = SpatialCorrelationSampler(
    kernel_size,
    patch,
    stride,
    pad,
    patch_dilation)

out = correlation_sampler(input1,input2)

print(out.shape)
print(input1[0])
print(input2[0])
print(out[0,:,:,0,0])

The output is:

tensor([[[2., 1., 2., 2., 3., 1., 3., 3., 3., 1.],
         [3., 2., 2., 3., 3., 1., 2., 3., 3., 2.],
         [1., 1., 3., 2., 3., 2., 1., 1., 2., 2.],
         [3., 2., 3., 2., 3., 1., 1., 3., 1., 1.],
         [2., 3., 3., 2., 1., 2., 3., 1., 2., 3.],
         [1., 1., 2., 3., 3., 1., 1., 2., 2., 1.],
         [3., 2., 1., 3., 3., 1., 3., 1., 3., 2.],
         [3., 3., 2., 2., 3., 1., 2., 2., 1., 2.],
         [1., 1., 3., 1., 3., 3., 1., 2., 3., 1.],
         [3., 2., 2., 1., 1., 1., 1., 1., 2., 2.]]], device='cuda:0',
       grad_fn=<SelectBackward>)
tensor([[[2., 2., 1., 1., 3., 1., 1., 1., 1., 3.],
         [2., 1., 3., 3., 2., 2., 1., 1., 2., 3.],
         [2., 2., 2., 2., 1., 2., 2., 1., 1., 2.],
         [1., 3., 3., 3., 3., 3., 1., 1., 1., 3.],
         [1., 3., 1., 2., 3., 1., 2., 3., 3., 1.],
         [3., 1., 3., 1., 3., 2., 1., 2., 1., 2.],
         [3., 2., 2., 1., 1., 2., 2., 1., 2., 1.],
         [3., 2., 2., 1., 1., 3., 2., 1., 1., 1.],
         [1., 2., 3., 1., 1., 3., 3., 3., 3., 1.],
         [3., 2., 1., 3., 3., 3., 2., 2., 2., 2.]]], device='cuda:0',
       grad_fn=<SelectBackward>)
torch.Size([1, 3, 3, 10, 10])
tensor([[0., 0., 0.],
        [0., 4., 4.],
        [0., 4., 2.]], device='cuda:0', grad_fn=<SelectBackward>)

I manually compute the "dilated correlation", and I guess the result of out[0,:,:,0,0] should be:

0 0 0
0 4 2
0 4 4

which is:

A[0,0]* Matrix(
B[-2,-2] B[-2,0] B[-2,2]
B[0,-2] B[0,0] B[0,2]
B[-2,-2] B[-2,0] B[-2,2]
)

Output are all zero

I have used this correlate module, but the output tensor are all zero. I don't know why. My input tensors are all 'torch.cuda.FloatTensor'.
When I use cpu version, the output have non zero values, but when it converts to cuda version, the output value are all zero.

an illegal memory access was encountered

Hi, when I use your code in pytorch 0.4.1, cuda 9.0, an error occurs:
THCudaCheck FAIL file=/opt/conda/conda-bld/pytorch_1532571933727/work/aten/src/THC/THCCachingHostAllocator.cpp line=271 error=77 : an illegal memory access was encountered
if I do not use the correlation layer, that would be ok.
Do you have any idea? Thank you!

Possible issue in setup.py

Error in pip3 install spatial-correlation-sampler

Hi, I try to install spatial_correlation_sampler with command,
pip3 install spatial_correlation_sampler
I get the follows errors,
error: command 'usr/local/cuda/bin/nvcc' failed with exit status 2.
I use Ubuntu16.04, CUDA8.0, Python3.5, Pytorch1.0.1， GCC 5.4
Can you provide your version of CUDA, Python, Pytorch and GCC?
Thank you!

Questions about the output shape

Hi @ClementPinard , thanks for this great work.
I'm having trouble comparing the output with your implementation against NVIDIA's. I observe that the output shape of your correlation_sampler is torch.Size([16, 3, 3, 100, 100]) while NVIDIA's implementation is torch.Size([16, 49, 94, 94]), given input size torch.Size([16, 64, 100, 100]) and other parameter shown in your benckmark scritps.
Would you please explain why you choose to output in this shape and how to convert them into NVIDIA's format? I didn't find an obvious conversion.
Thanks for your time.

Correlation always zero if multiple GPUs

The following code snippet reproduces the bug:

import torch
from spatial_correlation_sampler import spatial_correlation_sample


def run_spatial_corr(rank):
    corr = spatial_correlation_sample(torch.ones(1, 512, 12, 27).to(f"cuda:{rank}"),
                                      torch.ones(1, 512, 12, 27).to(f"cuda:{rank}")).mean()
    print(corr)

run_spatial_corr(0)
run_spatial_corr(1)

The expected output is:

tensor(512., device='cuda:0')
tensor(512., device='cuda:1')

However, it returns:

tensor(512., device='cuda:0')
tensor(0., device='cuda:1')

The output is as expected if the device ordinals are the same or everything is executed on the CPU. I run the code with Python 3.7 and PyTorch 1.2.

clang: error: unsupported option '-fopenmp'

Thanks for your valuable work! And I got this error when I find
python setup_cpu.py install on my MacBook pro without Cuda. Does it need Cuda installed when I just want to use it on CPU?(I have installed GCC)

undefined symbol: _ZTIN3c1021Auto

Hey, I got This error when I want to run:
import spatial_correlation_sampler_backend as correlation

"pip install spatial-correlation-sampler", passes. And then, when I import it in python,

from spatial_correlation_sampler import spatial_correlation_sample

lib/python3.6/site-packages/spatial_correlation_sampler_backend.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN3c1021AutogradMetaInterfaceE

pytorch 1.0.1.post2
gcc version 7.3.0 (Ubuntu 7.3.0-27ubuntu1~18.04)
Cuda compilation tools, release 10.0, V10.0.130

pip install without errors, but module import fails.

I tried installing with pip first. this worked without errors, but trying to import the package
import spatial_correlation_sampler
gave the error

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/adrian/research/envs/pytorch041/lib/python3.7/site-packages/spatial_correlation_sampler/__init__.py", line 1, in <module> from .spatial_correlation_sampler import SpatialCorrelationSampler, SpatialCorrelationSamplerFunction, spatial_correlation_sample File "/home/adrian/research/envs/pytorch041/lib/python3.7/site-packages/spatial_correlation_sampler/spatial_correlation_sampler.py", line 6, in <module> import spatial_correlation_sampler_backend as correlation ImportError: /home/adrian/research/envs/pytorch041/lib/python3.7/site-packages/spatial_correlation_sampler_backend.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZN2at19UndefinedTensorImpl10_singletonE

My environment was:
cuda 9.0
gcc 5.5
(also tried with cuda9.2/10 and gcc 7.3)
PyTorch 0.4.1
Python 3.7

How I solved it:

First I cloned the repository and tried with the environment above. This did not work and gave the errors:
... cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ Correlation_Module/correlation.cpp:1:29: fatal error: torch/extension.h: No such file or directory compilation terminated. error: command 'gcc' failed with exit status

I switched to PyTorch 1.0.1 environment and changed cuda version to 10.0 (and gcc to 7.3) and installed with setup.py again. This finally worked. Not sure why but wanted to share this in case someone else has the same trouble.

@ClementPinard The README says it is expected to compile with 0.4.1, perhaps this info is outdated?

Build error when using pytorch 1.7

When I upgraded to a RTX 3090 graphics card, I had to use cuda11 and the latest official version of PyTorch 1.7.

System Info:

The following error (is too long, there is only the last part) occurred while reinstalling this library from pip:

It looks like the same error as pip.

In order to determine where the problem is, I tried to install Pytorch 1.7 on a 2080ti computer, and the same error occurred when compiling this library. It uses cuda10.0 and python 3.8. However, using Pytorch 1.6 can install this library normally. My guess is that this error was introduced in the latest version of Pytorch 1.7.

I hope I can get your help, Thanks!

I installed the version 0.0.8 successfully, but got an import error.

I use the following command to install the package.
pip install spatial-correlation-sampler==0.0.8
And got the success message:

But when I try to import the package, I got the following error.

Could anyone help me to check what's wrong with it?

How to install on Mac CPU

I found #11 and I had the same problem. Following suggestions there I made the following changes but with no luck:

Removed .cu file from sources and changed CUDAExtension to CppExtension in setup.py (see attached setup.py.txt)
I had openmp installed
I built the wheel using CXX=clang++ CC=clang python3 setup.py build

The output is:

Why use `correlation_forward_cpp` instead of `correlation_backward_cpp`

Hi,
First, thanks a lot for your code. I have learnt a lot from it. I have found that the following line for cpu uses correlation_forward_cpp instead of correlation_backward_cpp

Pytorch-Correlation-extension/Correlation_Module/correlation.cpp

Line 143 in ca4e326

    
           AT_DISPATCH_FLOATING_TYPES(input1.scalar_type(), "correlation_forward_cpp", ([&] {

Is this a bug or other things I don't know?

Tf implementation

HI,

Would you be knowing of any easy to use ( like this one) , correlation layer in tensorflow.

Backward computation logic

Hi Clement, thank you for this repository, it is very helpful.

I am trying to modify it a bit to adapt to my task and I am struggling with the backward implementation. Could you please explain why the indexing logic is so different between the forward and backward pass?

More specifically, could you answer these questions?

why do we use only the thread index in the forward pass and two indices, namely ph_off and pw_off in the backward pass?
why THREADS_FORWARD is 32 and THREADS_BACKWARD is 5?

Thank you!

Feature-wise correlation

Hi,
I'm trying to implement feature-wise correlation, required for VCN: Volumetric Correspondence Networks.
The main difference is that feature-wise correlation does not sum over the channel dimension, the output cost volume is therefore (B x C x PatchH x PatchW x oH x oW) instead of (B x PatchH x PatchW x oH x oW).

The forward pass is already implemented here: https://github.com/gengshan-y/Pytorch-Correlation-extension
I'm trying to implement the backward pass, i thought that changing this
prod_sum[ph_off][pw_off] += gradOutput[n][ph][pw][i2][j2] * val;
to this
prod_sum[ph_off][pw_off] += gradOutput[n][c][ph][pw][i2][j2] * val;
would do the job, but it's not working.

I'm testing it with torch.autograd.gradcheck, and the jacobians from analytical and numerical are different (same values, but in different order).

Do you have any idea on how to implement the backward pass?

Hello,can I modify this code to implement my own function？

The original correlation operation was performed in a nearby area.For example,FlowNetC is d=4,so the cost volume is HxWx81,Now I want to change the matching area to a fixed area.This fixed patch's size is hxw,so the cost volume is HxWx(hxw). Can I implement this by modifying this code?
Looking forward to your suggestions

About the batch_size and kernel_size

Hello! Thanks for your valuable work again! I am confused about the batch size and the input1 input2. e.g. input1 = (16, 3, 224, 224) and input2 = (16, 3, 224, 224)，is the correlation of input1 and input2: cat_{i=0 => 15}{corr(input1[i, 3, 224, 224], input2[i, 3, 224, 224])}?
And the order of the input1 and input2 is: for a pixel x_{i,j} in input1, compute the patch around the location i, j in the input2. Is that right?
Finally, what is the kernel size meaning? I guess if kernel size = 1, it is: 1 pixel in the input1 => patch in the input2; kernel size=2: 4 pixel in the input1 => patch in the input2. I did not find the detail of flownet-C in Flownet and Flownet2.0 of the kernel size. Thanks for your help!

FlowNet2C training and validation

@ClementPinard Hi, thanks for your great work, I used it when training FlowNet2C. Install is well-done. I use SpatialCorrelationSampler(kernel_size=1, patch_size=21, stride=1, padding=0, dilation=1, dilation_patch=2) to replace the correlation function in the code. But the training loss didn't decrease and the validation EPE is very big. I don't know why, could you please give me some suggestions? Thanks very much.

Can I use pytorch==1.1 to install?

Hello,because of my cuda driver is not suit for pytorch1.2, and I can not update the service cuda driver version. So, if I use pytorch1.1, shall I modify some code?
I have test 1.1 version, and there is some unkown error.

error installing on Mac

Hi,
when I'm trying to install on Mac，here is the error:raise EnvironmentError('CUDA_HOME environment variable is not set).my pytorch version is 0.4.1，python is 3.6; because pytorch on Mac only support cpu, so I don't need set CUDA_HOME environment may be, any suggestion?

Segmentation Fault when running on a cluster

I got the segmentation fault when I submit my code to a cluster, but It is fine when I ran it on my personal computer. SO HOW TO FIX IT?

Padding clarification

Hi,

Can you please clarify the padding you do?
Looks like you assume "zero" padding which is equivalent to bounding the indices (in the cuda kernel code).
Is that right?

Thanks!

How can I use this correlation repo to replace nvidia's

In Nvidia correlation file , I use Correlation(pad_size=4, kernel_size=1, max_displacement=4, stride1=1, stride2=1, corr_multiply=1)
So,I use correlation_sampler = SpatialCorrelationSampler( kernel_size=1,patch_size=4,stride=1,padding=0,dilation_patch=1)
Given input size torch.Size([8, 64, 7, 6]),output shape of your correlation_sampler is torch.Size([8, 4, 4, 7, 6]), while NVIDIA's implementation is torch.Size([8, 81, 7, 6]).
Thus, the convert code is:
b, ph, pw, h, w = output.size()
Nvidia_shape = output.view(b, (ph+pw+1)^2, h, w)
Is my approach correct?

Compilation error on Windows

Hello, I'm trying to install this python library on Windows (I know, support is not guaranteed). I'm having a problem related to CUDA, here is the error message:

1 error detected in the compilation of "C:/Users/root/AppData/Local/Temp/tmpxft_0000a540_00000000-10_correlation_cuda_kernel.cpp1.ii".
correlation_cuda_kernel.cu
error: command 'C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v10.0\\bin\\nvcc.exe' failed with exit status 1

I don't understand why it keeps trying to use CUDA 10.0. In my path environment variable, the CUDA 9.2 is listed before CUDA 10.0 and my pytorch has been installed with CUDA 9.0 (because it won't install for CUDA 9.2, I don't know if this may cause a problem). I've read in other discussions that the CUDA version must be compatible with the gcc version, but I don't know mine and I don't know how to find it.

What should I do?

How to use it in DispNet?

good job!
but how can I use it in dispnet? which only consider the disparity in the single axis.

Best and thanks.

WITHIN_BOUNDS x/y bug

I noticed a discrepancy between the cpu and gpu code:
correlation.cpp says:
WITHIN_BOUNDS(x, y, H, W) (x >= 0 && x < W && y >= 0 && y < H)
correlation_cuda_kernel.cu says:
WITHIN_BOUNDS(x, y, H, W) (x >= 0 && x < H && y >= 0 && y < W)
I think this is a bug but maybe it does not affect anything.

Can't install through pip after update to 0.3

Hey @ClementPinard!

Starting yesterday after the update to the codebase, I stopped being able to install this on my system with specs:

Ubuntu 18.04
CUDA 10.0
gcc 7.4.0

The issue is similar to with an nvcc error in #1

Any ideas? Downgrading back to 0.2.1 works fine.
