  "global_step": 7000,
  "epoch": 2.911837350180693,
  "total_flos": 4.786937654858951e+18,

Image Preprocessing Note

This model was trained with images preprocessed to 448x448 resolution. While Qwen2.5-VL supports dynamic resolution:

• Best performance may be achieved with 448x448 images
• The model will still work well with other resolutions
• Native support for images from 56x56 to 3584x3584

Quick Start

from transformers import Qwen2_5_VLForConditionalGeneration, AutoProcessor
from PIL import Image
import torch

# Load model and processor
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "qwen25-vl-weather-7b",
    torch_dtype=torch.float16,
    device_map="auto"
)
processor = AutoProcessor.from_pretrained("qwen25-vl-weather-7b")

# Prepare your weather image
image = Image.open("weather_image.jpg")

# Create a prompt
prompt = "Analyze this weather image and describe the meteorological conditions."

# Format the message
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image"},
            {"type": "text", "text": prompt}
        ]
    }
]

# Process the input
text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = processor(
    text=[text],
    images=[image],
    padding=True,
    return_tensors="pt"
).to(model.device)

# Generate response
generated_ids = model.generate(**inputs, max_new_tokens=512)
generated_ids_trimmed = [
    out_ids[len(in_ids):] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)[0]

print(output_text)

Intended Use

This model is designed for:

• Weather Analysis: Interpreting meteorological imagery and data
• Educational Applications: Teaching weather concepts
• Research Support: Assisting in weather data analysis
• Operational Meteorology: Supporting weather forecasting workflows

Capabilities

The model excels at analyzing:

• Radar Imagery: Reflectivity, velocity, dual-polarization products
• Satellite Data: Visible, infrared, water vapor imagery
• Surface Charts: Weather maps, station plots, frontal analysis
• Upper Air Data: Soundings, constant pressure charts
• Model Output: Forecast charts, ensemble data
• Observational Data: Surface observations, meteograms

Example Prompts

Professional Analysis:

• "Analyze the radar reflectivity patterns and identify any supercell characteristics."
• "What does this water vapor imagery reveal about the jet stream position?"
• "Describe the atmospheric stability based on this sounding."

Educational:

• "Explain this weather pattern in simple terms."
• "What safety precautions should people take given these conditions?"

Limitations

• Specialized for meteorological imagery; may not perform well on general images
• Best with standard meteorological data formats and visualizations
• Responses reflect training data biases toward certain weather phenomena

Hardware Requirements

• Minimum VRAM: 16GB (with 8-bit quantization)
• Recommended VRAM: 24GB+ (for full precision)
• Optimal Performance: NVIDIA A100/H100 or RTX 4090/3090
