Question about Sun direction

[lt-wang]

InvRGBL/models/modules.py

Lines 281 to 286 in bf6b62e

	def get_sun_direction(self):
	return self.anno_sun_direction.to(device=self.device)
	# canon_light_dxy = self.sun_direction_[:2]
	# canon_light_d = torch.cat([canon_light_dxy, torch.ones(1).to(self.sun_direction.device)])
	# return canon_light_d / canon_light_d.norm()

Why is the sun direction kept fixed here?
