+*Note that we provide the master weights of BitVLA and perform online quantization. For actual memory savings, you may quantize the weights offline to 1.58-bit precision. We recommend using the [bitnet.cpp](https://github.com/microsoft/bitnet) inference framework to accurately measure the reduction in inference cost.*

+*Due to limited resources, we have not yet pre-trained BitVLA on a large-scale robotics dataset. We are actively working to secure additional compute resources to conduct this pre-training.*

+### Evaluation on VQA
 
 We use the [LMM-Eval](https://github.com/ustcwhy/BitVLA/tree/main/lmms-eval) toolkit to conduct evaluations on VQA tasks. We provide the [transformers repo](https://github.com/ustcwhy/BitVLA/tree/main/transformers) in which we modify the [modeling_llava.py](https://github.com/ustcwhy/BitVLA/blob/main/transformers/src/transformers/models/llava/modeling_llava.py) and [modeling_siglip.py](https://github.com/ustcwhy/BitVLA/blob/main/transformers/src/transformers/models/siglip/modeling_siglip.py) to support the W1.58-A8 quantization.

+#### 1. Preparing OFT
+We fine-tune BitVLA using OFT training shown in [OpenVLA-OFT](https://github.com/moojink/openvla-oft/tree/main). First setup the environment as required by that project. You can refer to [SETUP.md](https://github.com/moojink/openvla-oft/blob/main/SETUP.md) and [LIBERO.md](https://github.com/moojink/openvla-oft/blob/main/LIBERO.md) for detailed instructions.
+
+```
+conda create -n bitvla python=3.10 -y
+conda activate bitvla
+pip install torch==2.5.0 torchvision==0.20.0 torchaudio==2.5.0 --index-url https://download.pytorch.org/whl/cu124
+
+# or use the provided docker
+# docker run --name nvidia_24_07  --privileged --net=host --ipc=host --gpus=all -v /mnt:/mnt -v /tmp:/tmp -d nvcr.io/nvidia/pytorch:24.07-py3 sleep infinity
+
+cd BitVLA
+pip install -e openvla-oft/
+pip install -e transformers
+
+cd openvla-oft/
+
+# install LIBERO
+git clone https://github.com/Lifelong-Robot-Learning/LIBERO.git
+pip install -e LIBERO/
+# in BitVLA
+pip install -r experiments/robot/libero/libero_requirements.txt
+
+# install bitvla
+pip install -e bitvla/
+```
+
+We adopt the same dataset as OpenVLA-OFT for the fine-tuning on LIBERO. You can download the dataset from [HuggingFace](https://huggingface.co/datasets/openvla/modified_libero_rlds).
+
+```
+git clone git@hf.co:datasets/openvla/modified_libero_rlds
+```
+
+#### 2. OFT fine-tuning
+
+First convert the [BitVLA](https://huggingface.co/hongyuw/bitvla-bitsiglipL-224px-bf16) to a format compatible with the VLA codebase.
+
+```
+python convert_ckpt.py /path/to/bitvla-bitsiglipL-224px-bf16
+```
+
+After that, you can finetune the BitVLA using the following command. Here we take LIBERO spatial as an example:
+
+```
+torchrun --standalone --nnodes 1 --nproc-per-node 4 vla-scripts/finetune_bitnet.py \
+  --vla_path /path/to/bitvla-bitsiglipL-224px-bf16 \
+  --data_root_dir /path/to/modified_libero_rlds/ \
+  --dataset_name libero_spatial_no_noops \
+  --run_root_dir /path/to/save/your/ckpt \
+  --use_l1_regression True \
+  --warmup_steps 375 \
+  --use_lora False \
+  --num_images_in_input 2 \
+  --use_proprio True \
+  --batch_size 2 \
+  --grad_accumulation_steps 8 \
+  --learning_rate 1e-4 \
+  --max_steps 10001 \
+  --save_freq 10000 \
+  --save_latest_checkpoint_only False \
+  --image_aug True \
+  --run_id_note your_id
+```
+
+### Evaluation on LIBERO
+
+You can download our fine-tuned BitVLA models from [HuggingFace](https://huggingface.co/collections/hongyuw/bitvla-68468fb1e3aae15dd8a4e36e). As an example for spatial set in LIBERO, run the following script for evaluation:
+
+```
+python experiments/robot/libero/run_libero_eval_bitnet.py \
+    --pretrained_checkpoint  /path/to/ft-bitvla-bitsiglipL-224px-libero_spatial-bf16 \
+    --task_suite_name libero_spatial \
+    --info_in_path "information you want to show in path" \
+    --model_family "bitnet" 
+```
