Missing testbed.exe & instant-ngp.exe

[Eamon-q]

Hi,

Really excited to try this out and I have been working through the instructions to get everything working.

Everything seems to have worked so far and I have managed to run a series of images through COLMAP and now have the json file next to my images ready for the next step.

When I run:
C:\ngp\instant-ngp\build\testbed.exe --scene data/image-set-name

I get this back:
'C:\ngp\instant-ngp\build\testbed.exe' is not recognized as an internal or external command,
operable program or batch file.

I noticed that there is no testbed.exe file in the build folder and saw, (in these discussions) that it was already suggested to someone else with the same issue, to use the instant-ngp.exe file in the root folder instead. However this does not work for me and when i look, there is also no instant-ngp.exe file there.

Will really appreciate your help.

Thanks!

Eamon

Hope for some ideas!

Thanks

Hi,

In the meantime I solved this. Firstly, you no longer need "testbed.exe", but instead should look for "instant-ngp.exe". However in my instance I was also missing the instant-ngp.exe file. If you don't have the .exe file then something has gone wrong when running the CMake build. I think for me I was using the wrong python version. If you get stuck, let me know and I'll have a look back through my notes.

Good luck!

Thanks a lot for this. I do not have the instant-ngp.exe file as well.
Actually, I had some problem running the cmake build and I ended up with this specs:
D:\tutorial\ngp\instant-ngp>cmake -D CUDA_TOOLKIT_ROOT_DIR=D:\tutorial\NVIDIAGPUComputingToolkit\CUDA\v11.6\bin\ncvv.exe -D TCNN_CUDA_ARCHITECTURES=61 -D CMAKE_CUDA_COMPILER=D:\tutorial\NVIDIAGPUComputingToolkit\CUDA\v11.6\bin\ncvv.exe

where I had to remove the -B build part otherwhise I was running into the following error:

CMake Error at dependencies/tiny-cuda-nn/dependencies/fmt/CMakeLists.txt:234 (target_compile_features):
target_compile_features no known features for CXX compiler

"MSVC"

Could this be the issue?

Nonetheless, without -B build, it seems to work fine despite having some warnings such as:
-CMake Warning:
No source or binary directory provided. Both will be assumed to be the
same as the current working directory, but note that this warning will
become a fatal error in future CMake releases.

all these sound a bit black boxes for me... I am pretty new to all this.
Many thanks for your help!!

Hi,

This is all quite new for me too. But my approach to get everything working was to ensure I had all the necessary resources. Have you installed CMake?

One thing I saw in the text you shared is that Vulkan doesn't seem to be installed. Vulkan massively improved the results I was getting from my image sets. (just a tip for once you get everything running).

I have actually manged this morning to make it work and I have successfully trained the model. I will play around to have Vulkan. But now I ma stuck with memory limitation while lunching the GUI...

Thanks a lot
