Note:
 If you're not sure why an attribute is not being inlined as a
 constant, you can run *dump_alias_db* on
 frozen_module.forward.graph to see if freezing has detected the
 attribute is being modified.

Note:
 Because freezing makes weights constants and removes module
 hierarchy, *to* and other nn.Module methods to manipulate device
 or dtype no longer work. As a workaround, You can remap devices
 by specifying *map_location* in *torch.jit.load*, however device-
 specific logic may have been baked into the model.
