Colab error: ModuleNotFoundError: No module named '_gridencoder'

[erikestany]

Hello. I have this error with colab:

ModuleNotFoundError: No module named '_gridencoder'
During handling of the above exception, another exception occurred:

CalledProcessError Traceback (most recent call last)

11 frames

CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.
The above exception was the direct cause of the following exception:

I solved this by following the environment guide "Ubuntu 22 with torch 1.12 & CUDA 11.6 on a V100.":
pip install torch==1.12.0+cu116 torchvision==0.13.0+cu116 torchaudio==0.12.0 --extra-index-url https://download.pytorch.org/whl/cu116

[DongChengdongHangZhou]

Yes, thank you, bro. Following your suggestion I have successfully resolved this problem.

Hi. I was able to fix it, and it generates the videos, but when it has to generate the mesh, this error appears. Some idea? Thanks.
