Just giving a ping! I would love an answer to this thank you!

Hello, I have the same problem, and how do you deal with it?

[SpicyMelonYT]

No clue sorry, I never received help and stopped trying. Try asking Bing Chat Or Chatgpt!

[luis-guerraf]

Any news on this?

[SpicyMelonYT]

unfortunately no, i think this issue is burried under so much. Maybe try making another issue about it and it will cause all the "post duplicate" nazi's to show up and maybe help LOL

[luis-guerraf]

haha I fixed it on my end at least. I had replaced import _gridencoder with gridencoder (no underscore) following this advice https://github.com/eladrich/latent-nerf/issues/7#issuecomment-1416687218. I guess the name should match the name assigned to the CUDAExtension, rather than the package, in setup.py.

[SpicyMelonYT]

yeah taking out the underscores are usually how to do it. But i tried that a long time ago, didn't fix it for me unfortunately!

I fixed it by downgrading my CUDA version from 12.1 to 11.7, and then re-building the extensions. I am running on Windows without WSL.
