Red cube displayed upon running demo_gan.py

[rgga-16]

I ran demo_gan.py using the pre-trained gan_generator_voxels_sofas.to file. I made the following changes:

0. Copied gan_generator_voxels_sofas.to from examples folder to models folder.

1. Did pip install scipy==1.5.2

2. In rendering/__init__.py vertices, faces, normals, _ = skimage.measure.marching_cubes_lewiner(voxels, level=level, spacing=(2.0 / voxel_resolution, 2.0 / voxel_resolution, 2.0 / voxel_resolution)) to vertices, faces, normals, _ = skimage.measure.marching_cubes(voxels, level=level, spacing=(2.0 / voxel_resolution, 2.0 / voxel_resolution, 2.0 / voxel_resolution),method='lewiner')

3. In model/gan.py super(Generator, self).__init__(filename="generator.to") to super(Generator, self).__init__(filename="gan_generator_voxels_sofas.to")

I got this visualization as a result:

How do I resolve this?
