openvla policy intergration #10

DelinQu · 2024-07-05T10:27:04Z

This pull request integrates openvla policy. The evaluation scripts remain consistent with the original repo under ./scripts/

xuanlinli17 · 2024-07-05T16:10:49Z

Thanks for the contribution! Could you post the success rates for each task?

Could you post a source for the implementation of horizon, pred_action_horizon, exec_horizon, action ensemble, sticky gripper match, and do they match the real eval?

Code comments:

Remove " + OpenVLA policy" in readme
OpenVALInference -> OpenVLAInference
self.sticky_action_is_on is False in L147 of openvla_model.py: change to (not self.sticky_action_is_on)

DelinQu · 2024-07-06T14:00:54Z

Hi xuanlinli17, I have corrected all the typos. The implementation of horizon, pred_action_horizon, exec_horizon, action ensemble, etc., are migrating from octo. The evaluation results can be downloaded at
report_openvla.log

xuanlinli17 · 2024-07-06T15:15:39Z

I see. Might want to get help from the official authors to validate / revise the implementation as the Bridge results are near zero for some reason, and pick coke can has large variance across different backgrounds. Additionally, it's possible that OpenVLA might not follow Octo implementation in real deployment.

xuanlinli17 · 2024-07-06T15:19:24Z

Also you can modify https://github.com/simpler-env/SimplerEnv/blob/main/tools/calc_metrics_evaluation_videos.py to quickly summarize the results for OpenVLA (just put dummy numbers for the real numbers and don't push the script). You can ignore the nans.

HuFY-dev · 2024-07-07T01:55:59Z

I'm also working on implementing OpenVLA into SimplerEnv, and I had the same issue: OpenVLA fails drastically on Bridge. I wonder if that has anything to do with the controller mentioned in #11

sombitd · 2024-07-08T09:20:26Z

Same here, Severe lack of performance of OpenVLA on WindowX robot.

Hello @xuanlinli17, I tried the code above but openvla still fails on widowx tasks. Is it possibly an implementation problem? Should I set any params for widowx?

xuanlinli17 · 2024-07-22T19:50:57Z

Yeah that's my finding too, but I don't think the authors did some special treatments to evaluate OpenVLA on Bridge.

There might be some coordinate transforms on Bridge which is different.

erjiaxiao · 2024-07-23T00:41:31Z

@xuanlinli17 Thank you! I will continue to look into this. If I find any additional information or solutions, I'll make sure to share it with you.

When I run the scripts bash scripts/openvla_bridge.sh in ./SimplerEnv-OpenVLA, an error appears:

from simpler_env.policies.openvla.openvla_model import OpenVLAInference

ModuleNotFoundError: No module named 'simpler_env.policies.openvla'

How to fix it?

xuanlinli17 · 2024-07-28T16:51:04Z

^ Run pip install -e . in the SimplerEnv-OpenVLA repo. Also I don't think the authors have updated the scripts yet. I'll just add try to push some updates.

@hilookas Thanks for providing the results!
It seems like the open_drawer_variant_agg version is missing, as "horizontal sim variant avg success {'openvla': nan}".
Is it possible for you to also do that evaluation and edit your results list?

QuanyiLi · 2024-08-03T13:06:44Z

@hilookas Thank you for your great work! I want to try out the openVLA in the simulator as well. But I wonder why the performance in the sim is not as good as what is claimed by the paper in the real-world benchmark. It should not be due to the sim-to-real gap, right? Cause SIMPLER is designed to mitigate this gap.

xuanlinli17 · 2024-08-03T15:31:39Z

@QuanyiLi OpenVLA did 5 trials in real for each task (and there's no grid-based evals with >= 50 trials per task for Google Robot like in Simpler). Task settings like the cabinets and backgrounds used in the real world can also be different. We are requesting paired sim-real evaluation from Google following Simpler's protocol (and the same backgrounds, cabinets, etc).

How much memory is needed to run OpenVLA? I tried 3090 and 40GB A100 but both go out of memory.

QuanyiLi · 2024-08-05T14:29:53Z

@yxchng It takes me 15G vram for 4090, following the official instructions to use bf16.

1x3090 is enough. Just remember don't open env and inference process more than 1.

I do not have enough GPU resources attached to a Screen the Sapien simulator requires. :-(, running OpenVLA locally is quite a burden for most consumer-level PC.

Would you mind having a try on WidowX?

Simpler-OpenVLA on WidowX is known to have some strange behaviors that I don't yet know why... Would you investigate too?

@xuanlinli17 Maybe I didn't make myself clear, what I meant was that I ran the bash file inside the scripts file, but the robot simulation screen didn't appear. What am I supposed to do? Make the picture appear.

action = vla.predict_action(**inputs, unnorm_key="bridge_orig", do_sample=False)
print(action)

hello,

I'm curious why you didn't add 'In: What action should the robot take to {INSTRUCTION}?\nOut:' when inputting prompts to the processor? Would adding or not adding this sentence affect the results?

I would like to ask you, is it inadvisable to evaluate OpenVLA on the SIMPLER simulation platform, given that Widox performed very poorly on the Bridge dataset? Is there a better method to reproduce the results presented in the OpenVLA paper?

Hi guys, I would like to ask about is it inadvisable to evaluate OpenVLA on the SIMPLER simulation platform, given that Widox performed very poorly on the Bridge dataset? Is there a better method to reproduce the results presented in the OpenVLA paper?
Because the success rate of Widox evaluated on the SIMPLER platform for OpenVLA is only 0.

OpenVLA didn't apply any augmentation during training, compared to other models like RT-*. This could explain why they performed poorly on Simpler on WidowX (even though their result on Google Robot is fine).
