@JonLiu1993 forward me here to help fixing my issue.

everything I try from those links give me similar error:

@Tobe2d Paths with special characters may cause NVCC to interpret them as multiple files being passed in. Mabye try to modify it to a standardized path and please provide the error log: install-x64-windows-dbg-out.log

[Tobe2d]

Thanks @FrankXie05 for the reply,

Below is the log file:

install-x64-windows-dbg-out.log

[FrankXie05]

@Tobe2d Could you please try replacing the colmap in your vcpkg\ports directory with mine? I made a patch.

It seems that the upstream did not include when using the macro COLMAP_ADD_CUDA_SOURCES to pass in the header file of cuda https://github.com/colmap/colmap/blob/3.8/cmake/CMakeHelper.cmake#LL89C1-L107C34

colmap.zip

[Tobe2d]

Thanks @FrankXie05 I replaced the zip to colmap in vcpkg\ports I test building colmap and again got this:

@FrankXie05 Here you go! Unfortunately I don't have much experience with vcpkg and windows programming in general. Sorry for not providing all information upfront config-x64-windows-dbg-out.log

[bjornpiltz]

I ran in to this and the problem seems to be the stray /EHsc passed to nvcc (the unquoted one). If I remove it, I can get a single nvcc command to run.

I haven't been able to able to make the project to compile, though. Patching away this line didn't help.

[SharkWipf]

Issue is still present today. Following the steps to install nerfstudio on Windows, after compiling deps for over an hour, the COLMAP steps:

git clone https://github.com/microsoft/vcpkg
cd vcpkg
bootstrap-vcpkg.bat
vcpkg install colmap[cuda]:x64-windows

just fail with the same error. --head fails as well. nvcc fatal : A single input file is required for a non-link phase when an outputfile is specified CUDA toolkit 11.8.

Hi, I have the same error here. Apparently it has something to do with VSCode and some spaces in the paths

Hey all, I'm also getting a similar error. Has anyone managed to solve the issue? It's quite frustrating as I'd love to play with nerfstudio :/

[SharkWipf]

For nerfstudio, you may be able to run conda install colmap instead, or download it manually, and then point nerfstudio at the colmap binaries with ns-process-data video --colmap-cmd \path\to\colmap.exe. Another option is to run nerfstudio in WSL2. Then you can just add conda install colmap to your install commands and it should just work.

I have not tested either of these, I ended up installing it on Linux instead.

My bad, it's a conda-forge package, the correct command is: conda install -c conda-forge colmap

and even with the --colmap-cmd i get the following error : Could not find COLMAP. Please install COLMAP. See https://colmap.github.io/install.html for installation instructions.

You need to actually specify the full path to colmap.exe in the --colmap-cmd. So you first need to have a working colmap through some other method (i.e. conda or manual download), and then you need to point nerfstudio at its location using --colmap-command followed by the path to colmap.exe.

[adrien-StGir]

conda install -c conda-forge colmap -> that worked! thanks so much :D

[SharkWipf]

Ah, yes, welp. I ran into that as well, had it working for like 2 runs and then it broke again. That's when I decided to run it on Linux instead. I have no solution for that. You might have more luck with WSL2.

[alexmgee]

I decided to run it on Linux instead.

I am a total Linux idiot but have set it up before on a virtual machine. Could I run nerfstudio from Linux within a virtual machine?

Would it be possible to install Linux on my machine and dual-boot between Windows 11 and Linux?

No, not easily, you need the video card for CUDA, which the VM doesn't get access to. I'd suggest trying WSL2, which is like a Linux virtual machine integrated in Windows, with CUDA support.

Thank you for the response, I appreciate all the help we can get on this issue. Is the dual-boot concept not an option either?

I will look into WSL2... haven't had time yet to try the above methods.

[SharkWipf]

Is the dual-boot concept not an option either?

Dual boot is perfectly fine, though keep in mind you'll have to pre-distribute your disk space between operating systems, and NeRFs can use up a lot of space pretty quickly. I'm up to 500GB on my NeRF folder already.

That said, this is getting pretty off-topic for this issue/repo, and does not lead to a fix for the actual issue, so it might be time to move this elsewhere. The Nerfstudio Discord is a better place for individual support.

[Randomblock1]

I was able to get nerfstudio working by installing both colmap and mpir from conda-forge. But building it manually from vcpkg still doesn't work.

Hi, have you solved this problem? I have the same log error as you. If yes, may I know how you solve it? Thank you so much in advance

[adrien-StGir]

Sadly I never found a solution and ended up leaving it and using luma.ai and volunga to process my nerfs. :/ Sad to hear it’s still an issue. Any further ideas welcome.

Hi there - after hours of downloading and building vcpkg on Windows 10 while trying to get nerfstudio to work, I had the same error message:

error: building colmap:x64-windows failed with: BUILD_FAILED

Thankfully, after a bit of tweaking and reading through this post and some other github comments, I was able to get nerfstudio to run smoothly across multiple hard drives, with the following steps. Your mileage may vary but hope these notes help -

• Install MS VS community 2022 along with desktop development C++ toolkit. (Make sure to uninstall any other versions of VS and VS BuildTools - having multiple versions caused me so many headaches!)

• Install CUDA 11.8 (make sure to include the Visual Studio Integration Component during CUDA install under Custom>CUDA>Visual Studio Integration)

• Install CUDNN - download and extract the folder from within the zip to your desktop (this validates correct user file permissions) and then copy and replace all of the folders (bin, include & lib) from the extracted cudnn folder into the CUDA toolkit folder here, replacing all existing files/folders: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8

• To be certain that the file paths were correct during installation, copy the 4 files from the CUDA toolkit extras folder: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\extras\visual_studio_integration\MSBuildExtensions

• Paste them into the VS plugins directory here, ensuring that the visual studio plugin is now definitely in the correct location: D:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\BuildCustomizations

• Here I'm using 'D:\Code\nerf-studio\env' as both the name of the env and the storage path of the env files (this lets you choose an install drive other than the default C:).

• By pointing your conda environment to this vcvarsall.bat file (quotes and all), you can run the cmake build process within the conda command prompt window. conda create --prefix D:\Code\nerf-studio\env -y python=3.8 conda activate D:\Code\nerf-studio\env python -m pip install --upgrade pip pip install torch==2.0.1+cu118 torchvision==0.15.2+cu118 --extra-index-url https://download.pytorch.org/whl/cu118 conda install -c "nvidia/label/cuda-11.8.0" cuda-toolkit cd\ D: cd D:\Code\nerf-studio\ git clone --recursive https://github.com/nvlabs/tiny-cuda-nn cd D:\Code\nerf-studio\tiny-cuda-nn "D:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x64 cmake . -B build cmake --build build --config RelWithDebInfo -j cd D:\Code\nerf-studio\tiny-cuda-nn\bindings\torch python setup.py install pip install nerfstudio conda install -c conda-forge colmap conda install -c conda-forge mpir cd D:\Code\nerf-studio\videos

• RUN THIS COMMAND to build the training data from 360 video [crop bottom 20% on 30s (3*30=90) video) : ns-process-data video --camera-type equirectangular --images-per-equirect 8 --num-frames-target 90 --crop-factor 0 0.2 0 0 --data D:\Code\nerf-studio\videos\input\test_360-video_50mbps_3840x1920_h.265_remove-grain.mp4 --output-dir D:\Code\nerf-studio\videos\output

• or image: ns-process-data images --camera-type equirectangular --crop-factor 0 0.2 0 0 --data D:\Code\nerf-studio\images\input --output-dir D:\Code\nerf-studio\images\output

• At this point, I was able visualize the data with either of these commands: ns-train nerfacto --data D:\Code\nerf-studio\videos\output ns-train nerfacto --data D:\Code\nerf-studio\images\output

• This took about 1 hour to complete processing the NERF from a 30-second, 360 degree video from an Insta360 ONE X2 Camera using an i9-9700 CPU, with 32GB RAM and an NVIDIA RTX 3070 GPU with 8GB VRAM.

• After that's done, you can view it again any time with this command: ns-viewer --load-config D:\Code\nerf-studio\videos\outputs\output\nerfacto\2023-09-01_155318\config.yml

• Exporting a point cloud of the trained data was as easy as: ns-export pointcloud --load-config D:\Code\nerf-studio\videos\outputs\output\nerfacto\2023-09-01_155318\config.yml --output-dir D:\Code\nerf-studio\videos\exports\pcd\ --num-points 1000000 --remove-outliers True --normal-method open3d --use-bounding-box True --bounding-box-min -1 -1 -1 --bounding-box-max 1 1 1

[tfwittwer]

The build error is caused by the /EHsc argument in the nvcc command line. A manual workaround is to edit the build.ninja file and run ninja directly.

[SamuelJamesFisher]

Same issue, Have tried making sure there are no spaces in ANY paths. Cuda, vcpkg, visual studio all have no spaces in their paths.

C:\NVIDIAGPU C:\Tool\vcpkg C:\Tool\VisualStudio

Log. install-x64-windows-dbg-out.log

The issue is not with spaces, but with arguments with slashes - in this case the /EHsc command. This can be deleted from the ninja files. In one case I encountered it was possible to edit the build.ninja file, in other cases I had to edit the rules.ninja file and delete the $FLAGS argument in the nvcc calls. Then run ninja from a Visual Studio Developer Prompt as shown on line 3 of your log.

Still no luck tried both and a combination of the two. Taken from the Visual Studio Developer Prompt with the command: C:/Tool/VisualStudio/Common7/IDE/CommonExtensions/Microsoft/CMake/Ninja/ninja.exe -v -v -j17 install All /EHsc commands were deleted from build.ninja and $FLAGS were deleted from rules .ninja where the exe was nvcc.exe

Which version of Visual Studio and CUDA do you use? I haven't encountered those errors using the latest version of Visual Studio 2022 and CUDA 12.1.

[SamuelJamesFisher]

Visual studio 2019 per colmaps recomendation, cuda 12.2. Have just tried visual studio 2022 latest version and 12.1 same errors.

[SamuelJamesFisher]

Just an update. I gave up on windows, installed a linux os on dual-boot, had colmap working in around an hour. I spent over a week trying to sort this error on windows.

I ran in to this and the problem seems to be the stray /EHsc passed to nvcc (the unquoted one). If I remove it, I can get a single nvcc command to run.

I haven't been able to able to make the project to compile, though. Patching away this line didn't help.

I ran into the same exact behavior/issue, but adding the following hack that essentially "escapes" the extra \EHsc fixed it for me.

if(CUDA_ENABLED)
    COLMAP_ADD_LIBRARY(
        NAME colmap_mvs_cuda
        ...
    )
    # Hack for the extra \EHsc that gets added on Windows to the nvcc compile line, which causes the error:
    # "nvcc fatal: A single input file is required for a non-link phase when an outputfile is specified..."
    if(IS_MSVC)
        set_target_properties(colmap_mvs_cuda PROPERTIES COMPILE_OPTIONS -Xcompiler)
    endif()

For background info - this is caused by IMath and OpenEXR libraries (both dependencies of FreeImage which is dependency of colmap) declaring compile argument '/EHsc' in cmake as INTERFACE_COMPILE_OPTIONS, which is fine for C compiler, but not for CUDA(nvcc). The patch posted by longhuan2018 should work, it is also possible to replace the flag with conditional '$<$<NOT:$>:/EHsc>' so that it still applies to C targets.

Here is a patch for top level CMakeLists.txt i made before stumbling upon this thread:

in case anyone's still attempting nerfstudio, i kinda made it work

1. download a released zip version of colmap from git eg. https://github.com/colmap/colmap/releases/tag/3.9.1
2. unzip the file, rename the folder as colmap and put it to C:\
3. by now you should have C:\colmap\bin\colmap.exe
4. copy everything in C:\colmap\lib to C:\Windows\System32
5. go to system environment variables and put C:\colmap\bin in the Path
6. restart
7. try colmap in cmd, it should work now

Hi, I have the same error here. Apparently it has something to do with VSCode and some spaces in the paths

if so how did you solve ??
