All 6 prior steps executed correctly without issue.

SORRY - IT'S STEP 8 THAT FAILS.

I retried the next day, same failure to build for voxelize-cuda:

[YuliangXiu]

I just updated the code to remove the dependency on voxelize-cuda and set pytorch3d==0.7.1, you can have another try

[jnevin]

Fails with different error now in Step 8:

Thanks investigating YuliangXiu

我刚刚试了，也是同样的错误

@jnevin @1766685212

It does take some effort to install PyTorch3D successfully, but I finally make it and create the wheel file. Now you can have another try on Colab, and it will reduce the installation time from 20min to 2min.

hi @YuliangXiu tried again and final mesh generation fails. it complains about PyTorch3D being unavailable:

Will attempt again...

[jnevin]

^^ ModuleNotFoundError: No module named 'pytorch3d'

[jnevin]

@YuliangXiu the PyTorch3D wheel DOES seem to succeed now - thank you! The final creation of the result FAILS however when executing the next-to-last Running ECON step.

Here is the PyTorch3d wheel success:

But the same error as above is thrown with ModuleNotFoundError:

[YuliangXiu]

But this works for me, have you already set the "GPU" as follows?

[jnevin]

doing another run and will let you know results. looks like GPU matches yours:

[jnevin]

@YuliangXiu Notebook still fails in final step, although now it is complaining about Cuda device.

See the full flow of my notebook execution -- note that Nvida GPU matches yours.

[jnevin]

@YuliangXiu ^^ note that i am on "free" CoLab" account and not paying for Premium Colab service. So "standard GPU" only for me.

[YuliangXiu]

The PyTorch3D package is really annoying. I will check it later after flight landing.

[YuliangXiu]

@jnevin

Finally!

[jnevin]

@YuliangXiu will test and verify. Thank you for working so hard to resolve this.

[jnevin]

@YuliangXiu success in running the example!
