I don't know what it means that there is a map with a different number of channels. Perhaps it is a type of data pytorch3d cannot use and should ignore....

There are two texture map images, one is RGBA and the other is 2 channel. I haven't seen such 2 channel images, but it makes sense they could be greyscale...

`pytorch3d-0.7.2-cp38-cp38-linux_x86_64.whl` is for Python 3.8.x, not for Python 3.10.x (When you say x86, do you mean 32 bit? PyTorch3D does not distribute any 32 bit binaries.)

I have no experience with condacolab, and our instructions for installing pytorch3d on colab are assuming you aren't using it. I think it gives you something like a normal conda...

@Xin200203 The method of installing shown in the tutorials should work fine. Are you trying with non-vanilla colab e.g. with condacolab like the OP here?

Something a bit similar exists in [pytorch3d.vis.plotly_vis](https://github.com/facebookresearch/pytorch3d/blob/main/pytorch3d/vis/plotly_vis.py) . I don't know where that cube comes from though, and our code doesn't have an equivalent. It might be nice to allow...

Can you try playing with the znear and zfar inputs to the init of the FoVPerspectiveCameras ? Things too near or too far from the camera are deliberately ignored, but...

You can find the center yourself and then pass it as the `at` in look_at_view_transform.

These errors look like the errors in #1688, which we never got to the bottom of. (I am not sure WSL is easy to use for compiling CUDA in general.)...

Sorry, this is a known problem. A user provided a fix in https://github.com/facebookresearch/pytorch3d/pull/1689/files a few days ago. The PR should get merged soon, but can you make the changes locally...
