Do you know if I can run this on Windows or do I need WSL? I tried to run the demo using Git Bash, but unfortunately it isn't working.

thx for your great work!

Nik-V9 commented 11 months ago

Hi, we haven't tested on Windows yet.

I presume the setup would be similar to the instructions here: https://github.com/graphdeco-inria/gaussian-splatting#local-setup

Also, this video might be of help: https://youtu.be/UXtuigy_wYc?si=y87CrnBaZBPyBshL

I think the following should work if you have conda and the other CUDA 11.6 dependencies set:

SET DISTUTILS_USE_SDK=1 # Windows only
conda env create --file environment.yml
conda activate gaussian_splatting

nirmalsnair commented 11 months ago

Tested the iPhone online demo on Windows 10, it's working.

Install the conda environment as detailed here:

conda create -n splatam python=3.10
conda activate splatam
conda install -c "nvidia/label/cuda-11.6.0" cuda-toolkit
conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.6 -c pytorch -c conda-forge
pip install -r requirements.txt

Add conda to Git Bash as detailed here: a. Go to the folder: Anaconda/etc/profile.d/ b. Run echo ". ${PWD}/conda.sh" >> ~/.bashrc

In Git Bash, activate the splatam (conda) environment:

Nirmal@LAPTOP-HEKCV3H4 MINGW64 ~
$ conda activate splatam
(splatam)

Change current directory to SplaTAM folder:

Nirmal@LAPTOP-HEKCV3H4 MINGW64 ~
$ cd "C:\Users\Nirmal\Documents\SplaTAM"
(splatam)

Connect your iPhone and laptop to the same network. (I used a WiFi hotspot from my laptop to connect the iPhone, since connecting both devices to a WiFi network didn't work for me.)

Run the iPhone online demo script:

Nirmal@LAPTOP-HEKCV3H4 MINGW64 ~/Documents/SplaTAM (main)
$ python scripts/iphone_demo.py --config configs/iphone/online_demo.py

On the iPhone, open/restart the NeRF Capture app. It should show 1 Connection(s), if connection is established to the laptop. Click Send to capture and send a frame. (Need to capture 10 frames.)

Nik-V9 commented 11 months ago

Hi, for help with the diff-gaussian-rasterization compilation on Windows, I would recommend referring to the 3DGS repo: https://github.com/graphdeco-inria/gaussian-splatting?tab=readme-ov-file#faq

Also, I think their closed issues have additional helpful info for Windows.

Nik-V9 commented 11 months ago
