v1.0.2 Unable to train/install ZipNerf

[Renbry]

Hi all,

With Nerfstudio v1.0.2 I have an issue of install failing when running the zipnerf model - Run : ns-train zipnerf It asks if I want to install the package, Yes.

Errors out on several Windows (10+11) machines with :

ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'C:\Users\renbr\anaconda3\envs\nerfstudio\Lib\site-packages\cv2\cv2.pyd' Consider using the --user option or check the permissions.

Error installing method.

Anyone know what to try next ? it's a fresh install (1hr old!) and happens across all my windows machines. Tried turning off ReadOnly and verified permissions on the file + folder. The "--user" command seems to need to be applied to the internal command that is run by ns-train to install the model so I don't have transparency into that cvar.

Thanks so much,

The the installation instructions here - https://docs.nerf.studio/nerfology/methods/zipnerf.html#installation

@tancik Thanks - spotted that but was hoping in-built functionality worked as it seemed to suggest.

Using this install method I get a completely different fail saying it 'couldn't find a supported Microsofot Visual C++ Installation' which is a surprise and annoyance. Using VS2022 successfully to install Nerfstudio and other repos so this is more of a dead end than the attempt to use the built-in install function.

Oh well!

I would suggest asking this question in the zipnerf repo since the error seems to exist there - https://github.com/SuLvXiangXin/zipnerf-pytorch

Thanks again, Found a discussion from July '23 with no answer. I'll dig harder!

@Renbry It seems to be related to the c++ environment? Maybe you can refer to the first and second answers here: https://stackoverflow.com/questions/71470989/python-setup-py-bdist-wheel-did-not-run-successfully
