I’m currently trying to work with open3d ML and Pytorch. I followed the installation guide given in the Open3D-ML github. However when I try to import open3d.ml.torch it sends me the following error : Exception: Open3D was not built with PyTorch support!

I’m working with

python 3.8
open3d 0.12.0
pytorch 1.6.0
cuda 10.1
Windows 10

Do you have any idea of where that error comes from ?

It does not support for Windows at the moment. You can install Ubuntu on WSL (Window Subsystem for Linux) on Windows OS, and install open3d-ml on ubuntu.

  • I have installed WSL2 on windows. I am using VS Code with WSL extension and it seems to be working. – Cary H Jun 25 '21 at 17:19

Can you check if the output of the following commands on Windows Terminal (or PowerShell) is:

  • wsl cat /proc/version 
    Linux version 5.10.16.3-microsoft-standard-WSL2
  • wsl --list 
    Ubuntu-20.04 (Standard)
  • wsl -l -v 
    Ubuntu-20.04    Running         2

In my experience, Open3D-ML with CUDA only works if you are a Windows Insider, updated the WSL kernel correctly, and you are using Ubuntu in WSL.

Also, check if the folder /usr/lib/wsl/lib exists. If not, then CUDA won't work in WSL.
