Error during intialization

[de-gozaru]

Hi,

I'm using torch-points3d version 1.3.0. I'm trying to initialize KPConv model using the following:

from torch_points3d.applications.kpconv import KPConv

unet = KPConv(
            architecture="unet",
            input_nc=0,
            num_layers=4,
            in_grid_size=0.03,
             )

however, I got the following error:

Traceback (most recent call last):

The same code was working with a previous version I installed 1 year ago.

What I'm doing wrong? your help is appreciated!

Thank you!

Hi, it looks like you may be using an outdated version of the code. I think you'll find the issue won't happen if you update to the latest master branch. Let me know if it helps!

Hi,

Thank you for your response. Actually, I think I'm using the latest version, I just installed the library one month ago.
