ERROR Uncaught exception: path::operator/(): expected a relative path!

I think I am specifying the network path incorrectly. Your help would be greatly appreciated. Thanks.

You'll want to pass a .json config to the --network argument. (The default would be in instant-ngp\configs\nerf\base.json)

Thanks for the response. I think the true issue is the path variable set-up to recognize my root location, which is C:\Tutorial\ngp\instant-ngp. I am now getting the error below after your suggestion.

How can I set-up the path variable to globally recognize my root location, which is C:\Tutorial\ngp\instant-ngp?

I am still getting the following error:
12:14:42 ERROR Network config path instant-ngp\configs\nerf\fox does not exist.

I am also facing similar issue:

C:\instant-ngp\instant-ngp\build>testbed.exe --scene "C:\instant-ngp\instant-ngp\data\nerf\fox"
19:30:43 INFO Loading NeRF dataset from
19:30:43 INFO C:\instant-ngp\instant-ngp\data\nerf\fox\transforms.json

19:30:44 ERROR Network config path configs\nerf\base.json does not exist.

Then I added the network path to the command but still it is throwing a new exception:
C:\instant-ngp\instant-ngp\build>testbed.exe --scene "C:\instant-ngp\instant-ngp\data\nerf\fox" --network "C:\instant-ngp\instant-ngp\configs\nerf\base.json"

I am not sure what's going wrong here. Any ideas?

--netowrk ./instant-ngp/configs/nerf/base.json passing it as a relative path like that fixed the problem for me

[gvbgeomatics]

Yes. Relative parth is required. We fixed it and enabled NVIDIA Instant NeRF on Cloud with the choice of GPU configurations and storage options for general public use. More details here: https://nebulacloud.ai/connect/blogs/how-to-use-nvidia-instant-nerf-on-nebula-cloud
