ImportError: cannot import name 'Textures'

from the google colab could be due to pytorch3d version?

The same issue was raised in PIFu repository and the pull request is merged there. Unfortunately I don't have bandwidth to change the code in PIFuHD for now. But you can make the same modification in pifuhd repo as well. Thanks.

I'm seeing same error, very annoying.

after making the suggested change, still getting another error:

Facing same issue :/

I don't see any documentation under https://pytorch3d.readthedocs.io/en/latest/modules/renderer/texturing.html. I guess the moved texturing from structures to render class.

Same issue
PyTorch3D is updated to v 0.2.5 (https://github.com/facebookresearch/pytorch3d/releases)
Now, from pytorch3d.structures import Textures -->
from pytorch3d.renderer import TexturesUV, TexturesVertex, TexturesAtlas

Line 42
from pytorch3d.renderer import ( look_at_view_transform, OpenGLOrthographicCameras, PointLights, DirectionalLights, Materials, RasterizationSettings, MeshRenderer, MeshRasterizer, TexturedSoftPhongShader, HardPhongShader )
to
from pytorch3d.renderer import ( look_at_view_transform, OpenGLOrthographicCameras, PointLights, DirectionalLights, Materials, RasterizationSettings, MeshRenderer, MeshRasterizer, SoftPhongShader, HardPhongShader, TexturesUV, TexturesVertex, TexturesAtlas )

Line 111
textures = Textures(verts_rgb=verts_rgb_colors) wo_textures = Textures(verts_rgb=torch.ones_like(verts_rgb_colors)*0.75)
to
textures = TexturesVertex(verts_rgb=verts_rgb_colors) wo_textures = TexturesVertex(verts_rgb=torch.ones_like(verts_rgb_colors)*0.75)

After that,it work :)

@GambleV after applying chagnges you recommended above, I am getting the following error.

    114     verts_rgb_colors = get_verts_rgb_colors(obj_path)
    115     verts_rgb_colors = torch.from_numpy(verts_rgb_colors).to(device)
--> 116     textures = TexturesVertex(verts_rgb=verts_rgb_colors)
    117     wo_textures = TexturesVertex(verts_rgb=torch.ones_like(verts_rgb_colors)*0.75)
    118 

TypeError: __init__() got an unexpected keyword argument 'verts_rgb'

Any help? Thanks

[WozLai]

@farazBhatti , apologize for post wrong ans. The two lines should be changed to
textures = TexturesVertex(verts_features=verts_rgb_colors)
wo_textures = TexturesVertex(verts_features=torch.ones_like(verts_rgb_colors)*0.75)

Try this :)

[wanfuse123]

where in the google colab do I put this?

Thanks!!!

[wanfuse123]

Also, Do you have detailed instructions for running this locally? Or in a docker VM (with and without nvidai-cuda support?)

[WozLai]

@wanfuse123
git+url ?
I just test it in google colab for PIFuHD example.

[wanfuse123]

What FILE is this change supposed to be made in ? I downloaded the project , installed all its dependencies, and I get the error. Can you tell me what file these lines are changed in.

grep -R "from pytorch3d.renderer import" . turns up nothing in the pifudh directory.

Thanks for being patient!

Try from pytorch3d.structures import Meshes

[WozLai]

This issue occur in lib/colab_util.py when use from pytorch3d.structures import Textures. But new version Textures is deprecated.

[EnricoBeltramo]

@EnricoBeltramo
Line 106
Try from pytorch3d.structures import Meshes

I suppose meshes doesn't exist anymore in pytorch3d:

---> 41 from pytorch3d.renderer import TexturesUV, TexturesVertex, TexturesAtlas, Meshes
42 from pytorch3d.renderer import ( look_at_view_transform, OpenGLOrthographicCameras, PointLights, DirectionalLights, Materials, RasterizationSettings, MeshRenderer, MeshRasterizer, SoftPhongShader, HardPhongShader, TexturesUV, TexturesVertex, TexturesAtlas )
43

ImportError: cannot import name 'Meshes'

Some one know the correct version of pytorch3d in order to change colab here:
!pip install 'git+https://github.com/facebookresearch/pytorch3d.git@stable'
and align to version of pytorch3d the SW was tested with?

[shunsukesaito]

Sorry for having you guys wait for long time. I just made fix and it should be working now!
