Instant NGP Gets stuck when I start training

[lightningthief873]

I extracted the video data using COLMAP and stored it in a directory. The same data works very well for the model Nerfacto, but the whole system gets stuck when It comes to Instant NGP. No output is visible afterwards.

Here are my system details:

1. AWS EC2 instant, currently accessed using SSH, using the Anaconda environment internally.
2. Ubuntu 24.04
3. Nvidia Cuda Toolkit version 12.4 (had to install this because of the GPU driver)
4. Nvidia GPU: Tesla T4.
5. CPU: 16 gigs RAM, 4 cores.

The only command I ran for training:

ns-train instant-ngp --data data/nerfstudio/video

According to some previous issues I read, I had to clear some cache from the ./cache folder, but that didn't work too.

Current stopping point (No output comes after this):

Have you been able to figure out your issue?

[lightningthief873]

No, I wasn't able to. The last time I debugged the issue, the error was that instant ngp doesn't work on toolkit version 12.4 or greater. It needs to be a lower version.
