PALM E

? PALM-E: A Multi-Modal AI Model

This is the open source implementation of the SOTA multi-modality foundation model "PALM-E: An Embodied Multimodal Language Model" from Google, PALM-E is a single large embodied multimodal model, that can address a variety of embodied reasoning tasks, from a variety of observation modalities, on multiple embodiments, and further, exhibits positive transfer: the model benefits from diverse joint training across internet-scale language, vision, and visual-language domains.

Note

• This is just the model architecture, no pretrained weights, no tokenizer
• To actually conduct inference you would need to --> setup tokenizer for text and images -> train -> inference
• If you are doing research into multi modal models and would like to train this model and release it open source join the agora lab by clicking on the banner!

Appreciation

• All the creators in Agora, Join Agora the community of AI engineers changing the world with their creations.
• LucidRains for inspiring me to devote myself to open source AI

Quick Start

Installation ?

pip install palme

Usage ?

import torch
from palme.model import PalmE

#usage
img = torch.randn(1, 3, 256, 256)
caption = torch.randint(0, 20000, (1, 1024))

model = PalmE()
output = model(img, caption)
print(output.shape) # (1, 1024, 20000)

Dataset Strategy

Here is a summary table of the key datasets mentioned in the paper:

Dataset	Tasks	Size	Link
TAMP	Robotic manipulation planning, VQA	96,000 scenes	Custom dataset
Language Table	Robotic manipulation planning	Custom dataset	Link
Mobile Manipulation	Robotic navigation and manipulation planning, VQA	2912 sequences	Based on SayCan dataset
WebLI	Image-text retrieval	66M image-caption pairs	Link
VQAv2	Visual question answering	1.1M questions on COCO images	Link
OK-VQA	Visual question answering requiring external knowledge	14,031 questions on COCO images	Link
COCO	Image captioning	330K images with captions	Link
Wikipedia	Text corpus	N/A	Link

The key robotics datasets were collected specifically for this work, while the larger vision-language datasets (WebLI, VQAv2, OK-VQA, COCO) are standard benchmarks in that field. The datasets range from tens of thousands of examples for the robotics domains to tens of millions for the internet-scale vision-language data.

Roadmap

• URGENT: Debug Tokenizer, make sure multi-modal inputs work.
• Create Dataset Strategy
• Upload Training Documentation
• Get Training running with multi-modal
