quick_start/17872_normalized.obj: Permission denied

[A6248384]

Thank for this project! I got an error when I run python quick_start.py

Is there any solution?

[zhan-xu]

are you able to run binvox byitself?

[A6248384]

I run ./binvox and this is the result.

Yeah you need to pass a model to it and test. Check binvox webpage for the usage.

I try this command. !./binvox -d 88 -pb quick_start/17872_remesh.obj

Did you get quick_start/17872_normalized.obj?

[A6248384]

Yes, I got quick_start/17872_normalized.obj and quick_start/17872_normalized.mtl

I try python quick_start.py again and I got this. loading all networks... joint prediction network loaded. root prediction network loaded. connection prediction network loaded. skinning prediction network loaded. creating data for model ID 17872 gathering topological edges. calculating surface geodesic matrix. surface geodesic calculation: 9.594509601593018 seconds gathering geodesic edges.

when you try ./binvox -d 88 -pb quick_start/17872_remesh.obj, did you get quick_start/17872_remesh.binvox?

[A6248384]

when I try ./binvox -d 88 -pb quick_start/17872_remesh.obj. I didn't get quick_start/17872_remesh.binvox I just got following error.

[zhan-xu]

It is same issue as in #5 please check that thread. One quick try it to remove -pb

[zhan-xu]

Seems it is not easy to solve. I will update the code to get rid of binvox when I have time asap.

[A6248384]

Thank's for your reply. I think it's my setting problem. I use this project on virtual machine and can't display anything.
