[BUG] Invalid Keys Error when loading Encoder checkpoint #80

🔥 Describe the issue and expectation

When running tokenization, I got the following error

RuntimeError: Error(s) in loading state_dict for OneDAutoEncoder:
Invalid key(s) in state_dict: "decoder.positional_encodings", "encoder.query", mismatched dtypes or shape.

Root cause: using this command, we downloaded v0.5 weights, however, script cube3d/vq_vae_encode_decode.py defaults to v0.1 weights. That mismatches shapes for encoder.query and decoder.positional_encodings.

✅ Fix

Add --config-path cube3d/configs/open_model_v0.5.yaml to this tokenization command
