FileNotFoundError: [Errno 2] No such file or directory: 'data/grabnet_data/meshes.pt' in Google Colab demo

Hi Omid,

Thanks a lot for the amazing research work.

So I tried this for my own wine_bottle.obj file that has ~800 faces. Then all the cells before this one ran correctly.

How should I fix this one?

# run to see all grasps in one view

meshes = torch.load('data/grabnet_data/meshes.pt')
N = len(meshes)
col = int(5*np.sqrt(N/15))

all_meshes = []
bounds = meshes[0][0].bounds[:,:2]

dx = np.linalg.norm(bounds,axis=1).sum()
dx = .15

for i in range(N):

    obj = meshes[i][0]
    hand = meshes[i][1]

    a = i%col
    b = i//col

    offset = np.array([a*dx, b*dx, 0])*2.

    obj.vertices[:] += offset
    hand.vertices[:] += offset

    hand.set_vertex_colors(vc=[245, 191, 177])

    def_color = np.array([[102, 102, 102, 255]])
    if hasattr(obj.visual, 'vertex_colors') and (obj.visual.vertex_colors == np.repeat(def_color, obj.vertices.shape[0], axis=0)).all():
        obj.set_vertex_colors(vc=name_to_rgb['yellow'])

    all_meshes.append(obj)
    all_meshes.append(hand)

all_meshes = Mesh.concatenate_meshes(all_meshes)
all_meshes.show()

Error is:

Hi Mona, thanks for your interest. I just tried it on one of my meshes again and it works. Does it work with my meshes for you? If you send me your mesh I can try to figure it out.

thanks for your response. Really my bad. I uploaded obj. I converted it to ply in meshlab and now it worked. :)

Great, I will make sure to add support for obj files as well later.
