1. The exact command(s) you ran:

I ran the installation specified in (https://github.com/facebookresearch/pytorch3d/blob/master/INSTALL.md) and they worked perfectly fine.
only when I ran 
conda install pytorch3d -c pytorch3d
I got this issue

1. What you observed (including the full logs):

I found some other issues describing this, but it was closed with a solution where user built from source, does the conda install method not work for windows and is building from source the only option?

[bottler]

Pytorch3D does not currently have prebuilt packages for windows, on conda or otherwise. Building from source is the way forward, unless you can use Windows Subsystem for Linux etc.

Sure

Hey I was able to install pytorch3d after following this https://github.com/facebookresearch/pytorch3d/issues/172#issuecomment-620855810

but unfortunately when I run the following import
from pytorch3d.structures import Textures

I get the following error

ImportError: cannot import name 'Textures' from 'pytorch3d.structures' (C:Usersshettanaconda3envspytorch3dlibsite-packagespytorch3d-0.2.0-py3.8-win-amd64.eggpytorch3dstructures__init__.py)

what do you think is causing this?

I am setting up WSL and trying the conda install technique rn , but is there anyway to fix this?

[bottler]

I assume you have the built the latest code, not the release. The Textures object has been deprecated and has also moved from pytorch3d.structures to pytorch3d.renderer.

ahhh.. got it

thanks for replying
