ImportError: cannot import name 'csrc' from 'gsplat'

[sblat021]

Whenever I run ns-train with gaussian-splatting or igs2gs I get the following error (it works fine when using nerfacto):

Steps to reproduce the behavior:

1. After running COLMAP I run : ns-train gaussian-splatting --data output
2. First few steps seem to work fine and then it crashes once it gets to: Trainer.train_iteration
3. See error message above

Expected behavior I expect the COLMAP data to be trained using the gaussian-splatting or igs2gs model.

Additional context I followed the installation instructions exactly.

After nerfstudio dependencies I installed gsplat using: pip install git+https://github.com/nerfstudio-project/gsplat.git

After that I installed nerfstudio following instructions: git clone https://github.com/nerfstudio-project/nerfstudio.git cd nerfstudio pip install --upgrade pip setuptools pip install -e .

Visual Studio 2019 is installed including Desktop development with C+.

[sblat021]

This was resolved by uninstalling gsplat and reinstalling it like so: pip install git+https://github.com/nerfstudio-project/[email protected]

[Lanig77]

hi, what is the command to remove previous gsplat install. I have exactly the same issue

[javieryu]

Worked for me.

pip uninstall gsplat
pip install git+https://github.com/nerfstudio-project/[email protected]

[vincenzorin]

If the error persists, consider installing from

pip install git+https://github.com/nerfstudio-project/gsplat.git

as suggested in https://github.com/nerfstudio-project/nerfstudio/issues/2685#issuecomment-1859660671

[brentyi]

If you're seeing this issue in PyTorch 2.0, there's also a good chance it's a PyTorch bug. Upgrading to 2.1 fixes it for some systems.

(https://github.com/nerfstudio-project/nerfstudio/pull/2748 has notes on why)

[ILLCamaras]

I have PyTorch 2.1.2+cu118 installed

and I've tried: pip uninstall gsplat pip install git+https://github.com/nerfstudio-project/[email protected].

and I get

... Installing collected packages: gsplat ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. nerfstudio 1.0.0 requires gsplat==0.1.2.1, but you have gsplat 0.1.2 which is incompatible.

and also

pip uninstall gsplat pip install git+https://github.com/nerfstudio-project/[email protected].

and always

[brentyi]

Do you have an extra period here?

pip install git+https://github.com/nerfstudio-project/[email protected]. => pip install git+https://github.com/nerfstudio-project/[email protected] may work.

[ILLCamaras]

Install apparently work with only a Yellow warning: WARNING: Failed to remove contents in a temporary directory 'C:\Users\carlo\AppData\Local\Temp\pip-req-build-w_szq5df'. You can safely remove it manually.

But it doesn't and I can't run ns-train either as splatfacto or gaussian-splatting

Here the splatfacto error if could help

`Traceback (most recent call last): File "C:\Users\carlo\anaconda3\envs\nerfstudio\lib\runpy.py", line 194, in _run_module_as_main return _run_code(code, main_globals, None, File "C:\Users\carlo\anaconda3\envs\nerfstudio\lib\runpy.py", line 87, in run_code exec(code, run_globals) File "C:\Users\carlo\anaconda3\envs\nerfstudio\Scripts\ns-train.exe_main.py", line 4, in File "C:\Users\carlo\nerfstudio\nerfstudio\scripts\train.py", line 62, in from nerfstudio.configs.method_configs import AnnotatedBaseConfigUnion File "C:\Users\carlo\nerfstudio\nerfstudio\configs\method_configs.py", line 28, in from nerfstudio.configs.external_methods import get_external_methods File "C:\Users\carlo\nerfstudio\nerfstudio\configs\external_methods.py", line 24, in from nerfstudio.engine.trainer import TrainerConfig File "C:\Users\carlo\nerfstudio\nerfstudio\engine\trainer.py", line 39, in from nerfstudio.viewer_legacy.server.viewer_state import ViewerLegacyState File "C:\Users\carlo\nerfstudio\nerfstudio\viewer_legacy\server\viewer_state.py", line 41, in from nerfstudio.viewer_legacy.server.render_state_machine import RenderAction, RenderStateMachine File "C:\Users\carlo\nerfstudio\nerfstudio\viewer_legacy\server\render_state_machine.py", line 27, in from nerfstudio.models.gaussian_splatting import GaussianSplattingModel File "C:\Users\carlo\nerfstudio\nerfstudio\models\gaussian_splatting.py", line 30, in from gsplat.compute_cumulative_intersects import compute_cumulative_intersects ModuleNotFoundError: No module named 'gsplat.compute_cumulative_intersects'

[brentyi]

Are you on the latest version of nerfstudio?

[ILLCamaras]

That's my intention, I've completely rebuilt the anaconda environment installing:

git clone https://github.com/nerfstudio-project/nerfstudio.git cd nerfstudio pip install --upgrade pip setuptools pip install -e .

[brentyi]

Interesting, what's strange to me is this part of your error:

File "C:\Users\carlo\nerfstudio\nerfstudio\models\gaussian_splatting.py", line 30, in
from gsplat.compute_cumulative_intersects import compute_cumulative_intersects
ModuleNotFoundError: No module named 'gsplat.compute_cumulative_intersects'

We no longer have a gaussian_splatting.py in the repo, nor is the line that's producing this error present in the main branch when I search for it. Are you still getting this error despite a fresh clone of the repo?

[ILLCamaras]

I was rebuilding everything again but while installing it asked me to upgrade anaconda, I did it and I've lost ability to run Anaconda Navigator and installation went wrong. I'm uninstalling everything and start again from scratch. Thanks for help, I let you know.

[ILLCamaras]

I've reinstalled everything from Anaconda down to Nerfstudio following the guide but `ns-train splatfacto --data C:\Users\carlo\3DGSprojects\1750_CM --pipeline.model.cull-alpha-thresh 0.002 --max-num-iterations 100000 colmap --load_3D_points=True --downscale_factor 2' give me back the same error as before at first run, so I came back here and run

pip uninstall gsplat pip install git+https://github.com/nerfstudio-project/[email protected]

and also

pip uninstall gsplat pip install git+https://github.com/nerfstudio-project/gsplat.git

receiving the same error.

So I close the shell and run again the same command in a new one and now it's running! I'm around 15% now, it will take another 3h to complete. I'll post the results.

[ichsan2895]

Now, please run

conda env export --no-builds > environment-nerfstudio.yml

so, in the next time, if (someday) your system breaks and you must reinstall python/conda, you can replicate the previous environment by running:

conda env create -f environment-nerfstudio.yml -n nerfstudio

[ILLCamaras]

Thanks @ichsan2895

[ljbuckers]

Same issues as above and it solved for me - many thanks.

[xabila]

Yes that's crazy i also need to do it 2 times and now it's ok...

pip uninstall gsplat pip install git+https://github.com/nerfstudio-project/[email protected]

And now ok !!

[lukehollis]

This solved for me--and if it's helpful, I was able to resolve just by building from source w/o @version

pip install git+https://github.com/nerfstudio-project/gsplat.git

[Annkyotou]

I had the same problem, just for those who are using Windows system to install Gsplat, please try pip uninstall gsplat and then refer to (sometimes need set DISTUTILS_USE_SDK=1 as well) https://github.com/nerfstudio-project/gsplat/blob/main/docs/INSTALL_WIN.md
