The DECIMER 2.2 project tackles the OCSR (Optical Chemical Structure Recognition) challenge using cutting-edge computational intelligence methods. Our goal? To provide an automated, open-source software solution for chemical image recognition.

We've supercharged DECIMER with Google's TPU (Tensor Processing Unit) to handle datasets of over 1 million images with lightning speed!

1. 📦 TFRecord Files - Lightning-fast data reading
2. ☁️ Google Cloud Buckets - Efficient cloud storage solution
3. 🔄 TensorFlow Data Pipeline - Optimized data loading
4. ⚡ TPU Strategy - Harnessing the power of Google's TPUs

# Create a conda wonderland
conda create --name DECIMER python=3.10.0 -y
conda activate DECIMER

# Equip yourself with DECIMER
pip install decimer

from DECIMER import predict_SMILES

# Unleash the power of DECIMER
image_path = "path/to/your/chemical/masterpiece.jpg"
SMILES = predict_SMILES(image_path)
print(f"🎉 Decoded SMILES: {SMILES}")

🌟 New Feature Alert! 🌟

Our latest model brings the magic of AI to hand-drawn chemical structures!
