some problems when I run ./script/template.sh

[lingtengqiu]

And,also, when I delete the

rendered_seq, aux_seq = self.eval()  

in train.py, the question do not happen. I am very confused about the problem.

[gengshan-y]

The issue happened to me when environment/packages are not installed properly. There are two things to check:
Did you follow the readme to install with a new environment. Were you able to run it on the demo video?

[lingtengqiu]

Of course, I create conda environment based on your misc/banmo-cu113.yml.
The other problem is when i run # mode: fine tunning without pose correction
I see this problem, due to vars_np['mesh_rest'] is trimesh(0, 3). therefore vars_np['mesh_rest'].bounds return is None.

    pts = trimesh.bounds.corners(vars_np['mesh_rest'].bounds)
  File "/home/lingteng/anaconda3/envs/banmo-cu113/lib/python3.9/site-packages/trimesh/bounds.py", line 435, in corners
    raise ValueError('bounds must be (2,2) or (2,3)!')

I I am very interested in your series of work, and Could I get your contact information and ask your more details about ViSER and banmo ^ ^

[gengshan-y]

Thanks for the info. Can you provide a full backtrace log? I’ll look into this bug.

You may reach me by email.

Thank you for your kind reply

The issue about vars_np['mesh_rest'], I find the reason is that I annotated following code to smooth training since above problem.

# rendered_seq, aux_seq = self.eval()  

I find this code is very useful as it is able to update mesh['mesh_rest'].
I do not know if it is 3090 problem. no matter waht runing your code on demo video or my video, 'std::bad_alloc' happend. :（.

[gengshan-y]

It was tested on 3090 so I suppose it's not a hardware issue. The error log was not very useful unfortunately. It's likely a pytorch3d issue. While I'm trying to reproduce it on a new machine, there are a few things to try.

1. Install with [B. torch1.7+cu110] option.
2. or try moving verts and faces tensors to GPU by .to(self.device) before passing to pytorch3d.structures.meshes.Meshes at here

[lingtengqiu]

thanks for your suggestions.
[B. torch1.7+cu110] works well.

[cynthia-you]

Hi, could u tell me the sm of your 3090? If your compute capbility is sm_86, does sm_86 compatible torhc1.7 & cuda11.0? I have a 3070S GPU, and the NVIDIA CUDA DOC said the cuda11.0 support =<sm_80. I'm so confused.

[gengshan-y]

To use more recent architectures, you may need to replace these two lines with a compatible cuda version.

For reference I was using

cudatoolkit               11.6.0              hecad31d_10    conda-forge
cudatoolkit-dev           11.3.1           py39h3811e60_0    conda-forge

for 3090s.

Let me know if it does not work.

[gengshan-y]

Indeed, you may directly use the cuda 11.3 option for installation here.
