Describe the bug

In https://github.com/princeton-vl/infinigen/blob/66a449399f2f38d63e4b9aad689c02a4479f14df/infinigen/assets/trees/generate.py#L354, when specifying season="winter", I encountered the following error:

AssertionError: 
  In call to configurable 'TreeFactory' (<class 'infinigen.assets.trees.generate.TreeFactory'>)
  In call to configurable 'compose_scene' (<function compose_scene at 0x7f183862f2e0>)
  In call to configurable 'execute_tasks' (<function execute_tasks at 0x7f1701c3ad40>)

Steps to Reproduce

What version of the code were you using?

commit e8687f4ab5e809be28778fe42e26d26b414cca6a (HEAD, origin/main, origin/HEAD, main)

What command did you run?

Create launch_0228_debug_winter.gin with the following content:


random_season.weights = {'autumn': 0, 'spring': 0, 'summer': 0, 'winter': 1}

compose_scene.tree_density = 0.05 compose_scene.trees_chance = 1


2. In `generate_nature.py`, change https://github.com/princeton-vl/infinigen/blob/66a449399f2f38d63e4b9aad689c02a4479f14df/infinigen_examples/generate_nature.py#L109 to ```fac = trees.TreeFactory(np.random.randint(1e7), coarse=True, season=season)```

3. Run 
```# Generate a scene layout
python -m infinigen_examples.generate_nature --seed 0 --task coarse \
-g desert.gin simple.gin launch_0228_debug_winter.gin \
--output_folder outputs/hello_world/coarse \
--debug
