Installation Issue After Following Installation Instructions

🐛 Bugs / Unexpected behaviors

Hi all,

I've followed the installation instructions on the installation page, but the stable version of the library doesn't seem to be compatible with Python3.8 (which is the recommended version in the installation document).

Additionally, there seems to be a cuda error in building (although I'm not sure if that's my system or from the installation instructions).

NOTE: Please look at the existing list of Issues tagged with the label 'bug`. Only open a new issue if this bug has not already been reported. If an issue already exists, please comment there instead..

Instructions To Reproduce the Issue:

Please include the following (depending on what the issue is):

1. Any changes you made (git diff) or code you wrote: None
2. The exact command(s) you ran: I followed the installation instructions here: https://github.com/facebookresearch/pytorch3d/blob/master/INSTALL.md

> conda create -n pytorch3d python=3.8
> conda activate pytorch3d
> conda install -c pytorch pytorch torchvision cudatoolkit=10.2
> conda install -c conda-forge -c fvcore fvcore
> conda install jupyter
> pip install scikit-image matplotlib imageio
> pip install black isort flake8 flake8-bugbear flake8-comprehensions
> conda install pytorch3d -c pytorch3d

FWIW, I found this to be an issue with both the nightly and the stable build.

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

I got these errors:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - pytorch3d -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

The following specifications were found to be incompatible with your CUDA driver:

  - feature:/linux-64::__cuda==10.2=0

Your installed CUDA driver is: 10.2

[fishbotics]

Also, I see other people have had this issue with the Cuda driver when upgrading packages from 3.7 to 3.8 in Conda. It seems like it's not an issue with my system but with the metadata. Here is an example of how someone fixed it: KevinMusgrave/pytorch-metric-learning#55 (comment)

[bottler]

I don't think that's the problem: you aren't trying to build the conda packages, just use them. Can you paste the output of conda list and conda info please? Thanks

[fishbotics]

Thanks @bottler.

I just ran almost the same sequence of commands as you on basically the same platform (linux64, conda 4.8.3) and it worked. It seems like in your case the fvcore installation failed. You don't have fvcore or its dependency yacs in your environment. Do you get an error from conda install -c conda-forge -c fvcore fvcore?

I tried rerunning the command and it worked. I guess the installation of that package must have failed and caused the pytorch3d installation to fail. facepalm

Thanks for your help!
