# MolmoE 1B |
|
|
|
|
|
Molmo is a family of open vision-language models developed by the Allen Institute for AI. |
|
Molmo models are trained on PixMo, a dataset of 1 million, highly-curated image-text pairs. |
|
It has state-of-the-art performance among multimodal models with a similar size while being fully open-source. |
|
You can find all models in the Molmo family [here](https://huggingface.co/collections/allenai/molmo-66f379e6fe3b8ef090a8ca19). |
|
**Learn more** about the Molmo family [in our announcement blog post](https://molmo.allenai.org/blog). |
|
|
|
MolmoE-1B is a multimodal Mixture-of-Experts LLM with 1.5B active and 7.2B total parameters based on [OLMoE-1B-7B-0924](https://huggingface.co/allenai/OLMoE-1B-7B-0924). |
|
It nearly matches the performance of GPT-4V on both academic benchmarks and human evaluation, and achieves state-of-the-art performance among similarly-sized open multimodal models. |
|
|
|
This checkpoint is a **preview** of the Molmo release. All artifacts used in creating Molmo (PixMo dataset, training code, evaluations, intermediate checkpoints) will be made available at a later date, furthering our commitment to open-source AI development and reproducibility. |

|
## Quick Start |
|
|
|
To run MolmoE, first install dependencies: |
|
|
|
```bash |
|
# uninstall all tensorflow packages |
|
pip list --format=freeze | grep '^tensorflow' | cut -d= -f1 | xargs -n1 pip uninstall -y |
|
|
|
# install CPU-only version of tensorflow; used for image preprocessing |
|
pip install einops tensorflow-cpu torchvision |
|
``` |
|
|
|
Then, follow these steps: |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoProcessor, GenerationConfig |
|
from PIL import Image |
|
import requests |
|
|
|
# load the processor |
|
processor = AutoProcessor.from_pretrained( |
|
'allenai/MolmoE-1B-0924', |
|
trust_remote_code=True, |
|
torch_dtype='auto', |
|
device_map='auto' |
|
) |
|
|
|
# load the model |
|
model = AutoModelForCausalLM.from_pretrained( |
|
'allenai/MolmoE-1B-0924', |
|
trust_remote_code=True, |
|
torch_dtype='auto', |
|
device_map='auto' |
|
) |
|
|
|
# process the image and text |
|
inputs = processor.process( |
|
images=[Image.open(requests.get("https://picsum.photos/id/237/536/354", stream=True).raw)], |
|
text="Describe this image." |
|
) |
|
|
|
# move inputs to the correct device and make a batch of size 1 |
|
inputs = {k: v.to(model.device).unsqueeze(0) for k, v in inputs.items()} |
|
|
|
# generate output; maximum 200 new tokens; stop generation when <|endoftext|> is generated |
|
output = model.generate_from_batch( |
|
inputs, |
|
GenerationConfig(max_new_tokens=200, stop_strings="<|endoftext|>"), |
|
tokenizer=processor.tokenizer |
|
) |
|
|
|
# only get generated tokens; decode them to text |
|
generated_tokens = output[0,inputs['input_ids'].size(1):] |
|
generated_text = processor.tokenizer.decode(generated_tokens, skip_special_tokens=True) |
|
|
|
# print the generated text |
|
print(generated_text) |
|
|

## FAQs |
|
|
|
### I'm getting an error a broadcast error when processing images! |
|
|
|
Your image might not be in RGB format. You can convert it using the following code snippet: |
|
|
|
```python |
|
from PIL import Image |
|
|
|
image = Image.open(...) |
|
|
|
if image.mode != "RGB": |
|
image = image.convert("RGB") |
|
``` |
|
|
|
### Molmo doesn't work great with transparent images! |
|
|
|
We received reports that Molmo models might struggle with transparent images. |
|
For the time being, we recommend adding a white or dark background to your images before passing them to the model. The code snippet below shows how to do this using the Python Imaging Library (PIL): |
|
|
|
```python |
|
|
|
# Load the image |
|
url = "..." |
|
image = Image.open(requests.get(url, stream=True).raw) |
|
|
|
# Convert the image to grayscale to calculate brightness |
|
gray_image = image.convert('L') # Convert to grayscale |
|
|
|
# Calculate the average brightness |
|
stat = ImageStat.Stat(gray_image) |
|
average_brightness = stat.mean[0] # Get the average value |
|
|
|
# Define background color based on brightness (threshold can be adjusted) |
|
bg_color = (0, 0, 0) if average_brightness > 127 else (255, 255, 255) |
|
|
|
# Create a new image with the same size as the original, filled with the background color |
|
new_image = Image.new('RGB', image.size, bg_color) |
|
|
|
# Paste the original image on top of the background (use image as a mask if needed) |
|
new_image.paste(image, (0, 0), image if image.mode == 'RGBA' else None) |
|
|
|
# Now you can pass the new_image to Molmo |
|
processor = AutoProcessor.from_pretrained( |
|
'allenai/Molmo-7B-D-0924', |
|
trust_remote_code=True, |
|
torch_dtype='auto', |
|
device_map='auto' |
|
) |
|
``` |
