MINT-meta50

MINT checkpoint from outputs/btm_meta50_quant/checkpoints/002000/pretrained_model. The matching action tokenizer is MINT-tokenizer-meta50.

The vqvae_name_or_path config field points to huangrm/MINT-tokenizer-meta50/vqvae.pth. The MINT loader in this LeRobot checkout resolves that path using hf_hub_download.
