Install using Conda failed

Bugs / Unexpected behaviors

I am following the instructions in INSTALL.md (https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md#installation) to install pytorch3d using Conda but I get the issue nothing provides fvcore needed by pytorch3d-0.2.5-py36_cu101_pyt14

Instructions To Reproduce the Issue:

I ran the following commands to install the dependencies as explained in https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md#installation:

bash

conda create -n pytorch3d python=3.9
conda activate pytorch3d
conda install pytorch=1.13.0 torchvision pytorch-cuda=11.6 -c pytorch -c nvidia
conda install -c iopath iopath

Then, when running

bash

conda install pytorch3d -c pytorch3d

I get the following errors

bash
