TJ-chen/RDT-1B-LIBERO-Base

RDT-1B LIBERO Checkpoint

RDT-1B full fine-tuned on LIBERO-90 dataset (checkpoint-65000). Base model for all LIBERO tasks.

Model Information

• Base Model: RDT-1B (Residual Diffusion Transformer)
• Training Framework: DeepSpeed ZeRO Stage 2
• Precision: BF16

Checkpoint Contents

This checkpoint includes:

For Inference

• ema/model.safetensors - EMA model weights (recommended for inference)
• config.json - Model configuration

For Training

• pytorch_model/ - DeepSpeed distributed training checkpoint
  • bf16_zero_pp_rank_*_optim_states.pt - Optimizer states (ZeRO Stage 2)
  • mp_rank_00_model_states.pt - Model states
• scheduler.bin - Learning rate scheduler state
• random_states_*.pkl - Random number generator states
• zero_to_fp32.py - Utility to convert DeepSpeed checkpoint to FP32

Usage

For Inference

from transformers import AutoModel
import torch

# Load the EMA model for inference
model = AutoModel.from_pretrained(
    "TJ-chen/RDT-1B-LIBERO-Base",
    subfolder="ema",
    trust_remote_code=True
)
model.eval()

For Continued Training

Download the complete checkpoint and use DeepSpeed to resume training:

# The checkpoint can be loaded with DeepSpeed ZeRO Stage 2
# Make sure your training script is configured with the same DeepSpeed settings
