Can anyone help me with this?

[tomhostler]

Hands-up, i'm n00b!

1. Built a new PC from scratch to get into NeRF-making - not bad for life-long Mac fanboy ;-)
2. Got all the softwares (Cmake, CUDA, Python, Colmap etc) installed and running
3. Can run the Fox demo
4. When I try to use my own images with Colmap I get the following error

python /Users/NeRF/instant-ngp/scripts/colmap2nerf.py --colmap_matcher exhaustive --run_colmap --aabb_scale 16

Traceback (most recent call last):
File "C:\Users\NeRF\instant-ngp\scripts\colmap2nerf.py", line 19, in
import cv2
File "C:\Users\NeRF\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2_init_.py", line 8, in
from .cv2 import *
ImportError: DLL load failed while importing cv2: %1 is not a valid Win32 application.

After a lot of research, I have tried reinstalling Python, Colmap, Numpy etc - but can't get this to parse.

Windows 11, VS2022 and followed all the steps as closely as possible.

Any idea where I start to debug this one?

Thanks in advance

all of the version problems

Hey, thanks for the reply - but could you expand a little more please?

I installed all the versions of Cuda, CMake, Colmap and Python as directed - alongside VS 2022 on Win 11 Pro. I also installed the optional OptiX and Vulkan SDk too.

My own research suggested Numpy versioning issues, so I tried re-installing / upgrading that library too - but same issue.

I can parse the Python for the provided 'fox' demo scene, but when I try to run the Colmap2Nerf script I get that 'invalided Win32 application error'.

Again, my research suggests its often encountered with versioning issues of Python these libraries, but as I followed the directed instructions, i'm a bit stumped as to where to start.

Any more pointers greatly appreciated

Try VS2019 Apparently this is a windows adaptive issue tomhostler ***@***.***>于2022年10月18日 周二04:11写道：

Hey! Thanks for the tip ... it took an entire rebuild, this time using VS2019, and a lot of grappling with various PATH dependencies along the way for various Python libraries ... but I now have it working. Thanks!
