Can I install detectron2 on Win10?

We do not officially support windows, but given that maskrcnn-benchmark can run on win10, it probably won't take a lot of changes to run detectron2 on win10.

You can refer to https://github.com/facebookresearch/maskrcnn-benchmark/pull/741 or https://github.com/facebookresearch/maskrcnn-benchmark/issues/1042 to see what basic setups are needed, and welcome to share more if you have any luck with it.

thank you very much!

@jinyuan30 hello, have you installed detectron2 on win10 successfully?

@jinyuan30 hello, have you installed detectron2 on win10 successfully?

I turn to Ubuntu, and didn't try on Win10 cause I think maybe there are some unkonwn bug.

If it's of any use, attempting to compile without any changes to the code gives the following error: C:/Python37/lib/site-packages/torch/include\torch/csrc/jit/argument_spec.h(190): error: member "torch::jit::ArgumentSpecCreator::DEPTH_LIMIT" may not be initialized

pytorch/extension-cpp#37 references this problem, but using the patch suggested there raises 4 other issues all within the detectron2/layers/csrc/ROIAlign/ROIAlign_cuda.cu file, all related to type mismatching. Haven't been able to look further yet but maybe the CUDA files could be patched to run detectron2 on Windows.

I tried similar path.
And for the "/ROIAlign_cuda.cu" and "/ROIAlignRotated_cuda.cu",
change from each

dim3 grid(std::min(at::cuda::ATenCeilDiv(output_size, 512L), 4096L));
~
~
dim3 grid(std::min(at::cuda::ATenCeilDiv(grad.numel(), 512L), 4096L));

dim3 grid(std::min(at::cuda::ATenCeilDiv(static_cast<int64_t>(output_size), static_cast<int64_t>(512)), static_cast<int64_t>(4096)));
 ~
~
dim3 grid(std::min(at::cuda::ATenCeilDiv(static_cast<int64_t>(grad.numel()), static_cast<int64_t>(512)), static_cast<int64_t>(4096)));

looks like it worked.

@akinari1223 can you make a patch of your changes? Greatly appreciated.

EDIT: I see now it is mainly an issue in pytorch, never mind.

Can I install detectron2 on Win10?

yes you can. I have done for it. https://github.com/conansherry/detectron2

@ppwwyyxx we can do little change to support windows build. but it refer to pytorch files changed.

detectron2 change:

https://github.com/conansherry/detectron2/commit/4d57e128003b6c1f2d07cce75c1821de94f11683

pytorch change:

file1: 
  {your evn path}\Lib\site-packages\torch\include\torch\csrc\jit\argument_spec.h
  example:
  {C:\Miniconda3\envs\py36}\Lib\site-packages\torch\include\torch\csrc\jit\argument_spec.h(190)
    static constexpr size_t DEPTH_LIMIT = 128;
      change to -->
    static const size_t DEPTH_LIMIT = 128;
file2: 
  {your evn path}\Lib\site-packages\torch\include\pybind11\cast.h
  example:
  {C:\Miniconda3\envs\py36}\Lib\site-packages\torch\include\pybind11\cast.h(1449)
    explicit operator type&() { return *(this->value); }
      change to -->
    explicit operator type&() { return *((type*)this->value); }

@conansherry I tried your git of detectron2, having deleted both decetron2 and detectron2 repos from the pytoch folder. Reference to https://github.com/facebookresearch/detectron2/issues/232 , I am facing a similar set of issues building Detectron2 on Windows10 with CUDA 10.1 and VS 2019 @akinari1223 the changes on ROI cu files were implemented.

Im trying to build detectron2 via setup_py, and recieve the initial error mentioned:

1 error detected in the compilation of "C:/Users/aesnj/AppData/Local/Temp/tmpxft_00007274_00000000-10_deform_conv_cuda.cpp1.ii". error: command 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin\nvcc.exe' failed with exit status 1

When opennig the tmp file referenced I see:

the problem is your nvcc.exe and cl.exe is executable. please check your PATH environment.

find your vcvars64.bat and run it in the console.

@conansherry checked and ran vcvars64.bat in the Administrator x64 Native Tolls Command Prompt for VS 2019:

I had tried this before I cloned detectron2, I then clone your detectron2 into pytorch having moved the directory to it. Should I be cloning somewhere else, or is there anything else I can check for my enviroment variables?

@elnazsn1988 I search it in google. the similarity problem https://stackoverflow.com/questions/55663890/how-to-solve-nvcc-fatal-could-not-set-up-the-environment-for-microsoft-visua

you can use nvcc.exe to compile a simplest file to check if your environment is correct

@conansherry also, I have two argument_spec.h files, one sits in : C:\projects\pytorch\pytorch\torch\include\torch\csrc\jit , and the other in :
C:\projects\pytorch\pytorch\torch\csrc\jit

I change both to your specs, is this an issue?

the issue is nvcc.exe dosen't work correctly, Not related to pytorch.

@conansherry checked enviroment variables and did extended google search, / and %path% existed around tmp folder and Temp folder in enviroment variables, now removed - I get a different error https://github.com/facebookresearch/detectron2/issues/232 which was my original one before using your version of detectron2 :

1 error detected in the compilation of "C:/Users/aesnj/AppData/Local/Temp/tmpxft_00009754_00000000-10_deform_conv_cuda.cpp1.ii". error: command 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin\nvcc.exe' failed with exit status 1

@elnazsn1988 hello.cu:

#include <stdio.h>

__global__ void cuda_hello(){
    printf("Hello World from GPU!\n");
}

int main() {
    cuda_hello<<<1,1>>>(); 
    return 0;
}

do: nvcc hello.cu -o hello

if your env is correct, you will get a executable file named "hello.exe".

response to above is an "hello.exe" executable file in the path specified where I saved the hello.cu text document:

C:\Users\aesnj>nvcc hello.cu -o hello hello.cu Creating library hello.lib and object hello.exp

C:\Users\aesnj>

response to above is an "hello.exe" executable file in the path specified where I saved the hello.cu text document:

C:\Users\aesnj>nvcc hello.cu -o hello hello.cu Creating library hello.lib and object hello.exp C:\Users\aesnj>

The problem may occur when using python to call nvcc to compile. Sorry, I have not encountered a similar problem. My env list:

windows10 1903
visual studio 2019 enterprise
conda environment(python=3.6)
cuda10.1

you can search in google with key word "nvcc fatal : Could not set up the environment for Microsoft Visual Studio". There are many similar problems.

@conansherry could you possibly give a step by step commands list of how you built caffe2 on pytorch before all this, maybe I should wipe everything clean and start there and this is baffling. The file in the Temp folder its trying to access is the same one throwing up the error as https://github.com/pytorch/extension-cpp/issues/37#issue-459660244 , though in their case they get an explicit depth limit error.

@conansherry also do you also use Pytorch 1.3? as the normal detectron clone from the facebookresearch folder needed it I upgraded from 1.2 to 1.3 despite it being experimental

@conansherry also do you also use Pytorch 1.3? as the normal detectron clone from the facebookresearch folder needed it I upgraded from 1.2 to 1.3 despite it being experimental

I use pytorch1.3. and use "conda install pytorch torchvision cudatoolkit=10.1 -c pytorch" to install pytorch.

@conansherry did you have to build caffe2 seperatley after this? faced issues with Conda and as such used python without conda, could that be causing the errors? am slightly apprehensive of installing pytorch both on Conda and seperatley with python using VC tools 2019, as previously multiple version issues caused massive issues, the caffe2 build took 3 weeks.

I didn't build caffe2 or pytorh with sources.

@conansherry @ppwwyyxx so what worked for me, was using the conansherry detectron2, doing the changes here to every possible version of the documents saved on my system: https://github.com/facebookresearch/detectron2/issues/237#issuecomment-550101526 , changing the ROI files (rotated and not cu) and not sure if this means anything, but also cloning in parallel in Conda. I wasnt able to actually get a complete run in Conda, but somehow now it "seems" to be working.

If it's of any use to anyone I spent hours trying to install detectron2 on my windows 10 system. Here are the steps I followed based on other's solutions, thanks to the others who figured out a way for windows!:

Firstly, I changed the following lines in the files "/ROIAlign_cuda.cu" and "/ROIAlignRotated_cuda.cu" these files can be found in \detectron2\detectron2\layers\csrc\ROIAlignRotated change the following lines in both the files from this:

dim3 grid(std::min(at::cuda::ATenCeilDiv(output_size, 512L), 4096L));

dim3 grid(std::min(at::cuda::ATenCeilDiv(grad.numel(), 512L), 4096L));

to this:

dim3 grid(std::min(at::cuda::ATenCeilDiv(static_cast(output_size), static_cast(512)), static_cast(4096)));

dim3 grid(std::min(at::cuda::ATenCeilDiv(static_cast(grad.numel()), static_cast(512)), static_cast(4096)));

Then I changed a line in the following file(spec.h) {your evn path}\Lib\site-packages\torch\include\torch\csrc\jit\argument_spec.h(line 190) change this line from this: static constexpr size_t DEPTH_LIMIT = 128; to this: static const size_t DEPTH_LIMIT = 128;
Then I changed the following line in the following file (cast.h) change this line from this: {your evn path}\Lib\site-packages\torch\include\pybind11\cast.h(line 1449) to this: explicit operator type&() { return ((type)this->value); }
Even then I kept getting the Cuda(I have Cuda 9.2) and MS Visual studio incompatibility(MSV 2019,2017) errors. So I downloaded the CUDA 10.1.243 version and installed it.
Then I ran the " pip install -e . " command in the detectron2 folder from my Anaconda prompt.

My system settings:

Anaconda
Cuda 10.1.243 toolkit
Python 3.6
Pytorch 1.4
cudnn 7
torch vision 0.5
TensorFlow GPU 1.11
Microsoft Visual Studio 2019(community)
Windows 10

@anzy0621 Follow your steps to setup detectron2 on my windows 10. It works like a charm. Thank you.

Hello. I'm trying to install detectron2 on my windows 10. I followed some guides. But it seems this error is brand new.

Installing by pip install -e . successes. But when running demo.py, it fails with Not compiled with GPU support I think pip install cannot detect my CUDA (even I set PATH settings). So I tried to install with setup.py

Tried to install with setup.py because it detects CUDA OK.


(conda env) python setup.py install

you've run "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" before the build? The logs seem to complain about cl.exe, when you run that from the Command Prompt, do you see Microsoft (R) C/C++ Optimizing Compiler Version 19.24.28316 for x86 Copyright (C) Microsoft Corporation.

In my case, I installed cocoapi from philferriere but never needed to run setup.py for it.

@conansherry Instead of changing cast.h, I change the type of all_slot from constexpr to const, and the compilation works. Do you think it cause some bug?

Hi guys. I face a new issue. Following the above instructions, I successfully install detectron2 on Windows and run the demo successfully. But when I follow the train on single gpu tutorial:https://github.com/facebookresearch/detectron2/blob/master/GETTING_STARTED.md, I got an error: os has no attribute named getuid

I have searched this problem and found that only on Unix that os get attribute getuid(following is the url of the issue)https://github.com/Parsely/streamparse/issues/415

Have you guys finish training successfully? would someone come to explain this to me? I would any explanations!!!

WINDOWS安装已经搞定，WINDOWS安装有问题的加QQ群：669412407（注明detectron2）

Hi everyone, does this repository support win 10? yesterday, I have successfully installed detectron2 and run the demo successfully on win10, so I reconsider of using detectron2 for long term project if there is no major problem on windows 10 platform. Will it be okay ? best regards, Albert Christianto

@anzy0621 Do your instructions still hold true for detectron2 v 0.1.3?

It looks like in the latest version the changes to the .cu files are already done.

I am still getting this error: 5 errors detected in the compilation of "C:/Users/Windows/AppData/Local/Temp/tmpxft_00002f20_00000000-10_nms_rotated_cuda.cpp1.ii". error: command 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin\nvcc.exe' failed with exit status 1

@solarflarefx Yes, you are right. I checked out the code. They have made the required changes in ROIAlign_cuda.cu and ROIAlignRotated_cuda.cu

I still have the same error as you do. I have the exact same environment setup. Were you able to figure out a fix?

@conansherry

Thank you for the detailed steps provided. I installed detectron2 successfully, but when i'm running the python script i have noticing below error.

AttributeError: module 'detectron2.model_zoo' has no attribute 'get_config_file'

Could you please help me on to fix this error

Hi,I install detectron2 on win10 while failed with

C:\Users\87992\AppData\Roaming\Python\Python37\site-packages\torch\include\ATen/core/ivalue_inl.h(624): note: see reference to class template instantiation 'c10::ArrayRef' being compiled error: command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe' failed with exit status 2

could anybody tell me how to fixed it? I've tried modified argument_spec.h and cast.h but failed.

python 3.7.8 pytorch 1.4.0 torchvision 0.5.0 cuda 10.0 cudnn 7.4.2

In my experience installing Detectron2 on Windows 10 is perfectly possible, just a bit of a hassle. I would recommend installing all the dependencies separately (preferably through Anaconda, as doing this through PIP has resulted in errors for me in the past). After installing all the dependencies, you can simply use pip install 'git+https://github.com/facebookresearch/detectron2.git'.

At the time I'm writing this, I believe the only thing you cannot currently install through anaconda on Windows is cocotools. The command above will, however, install that just fine.

I have used Detectron2 like this for a few projects now, and it works great! Good luck everyone.

SITE=/mnt/c/Users/thomas.jungblut/AppData/Local/Programs/Python/Python37/Lib/site-packages
sed -i.bak -e 's/CONSTEXPR_EXCEPT_WIN_CUDA/const/g' "${SITE}/torch/include/torch/csrc/jit/api/module.h"
sed -i.bak -e 's/return \*(this->value)/return \*((type\*)this->value)/g' "${SITE}/torch/include/pybind11/cast.h"
sed -i.bak '/static constexpr Symbol Kind/d' "${SITE}/torch/include/torch/csrc/jit/ir/ir.h"

Change the site variable up to your installation path in Conda (D:/Users/huang/anaconda3/lib/site-packages).
Then a plain installation via git clone and python -m pip install -e detectron2 works as advertised.

facebookresearch / detectron2

Can I install detectron2 on Win10? #9
