nerfstudio: NeRFStudio + Volinga: Wrong ckpt format with NeRFStudio latest commit.
Describe the bug I have just updated NeRFStudio to the latest commit, and since then it seems that the ckpt (trained using ns-train volinga…) do not work with the Volinga convertor. After a successful upload I get the error code 607 and message “Wrong ckpt format”
To Reproduce Steps to reproduce the behavior:
- Train a NeRF using
ns-train volinga... - Upload the generated ckpt on Volinga’s website
- After few second that processing has started, it fails
Additional context Even if there is a thread on Volinga’s Discord server about this, I thought it could be useful to open an issue here too. It seems that the ckpt structure has changed.

That’s right, that is the setup you need.
If tiny cuda is not available, NeRFStudio will use vanilla Pytorch to train the model. The problem is that the way in which the model is stored in the ckpt varies depending if you use tiny cuda or not. At this moment, we only support the tiny cuda “format” on Volinga exporter. This is probably the reason for the failure.
