Overview

Converting models from TensorFlow to PyTorch is a common task for developers transitioning between frameworks. This guide provides a step-by-step approach to help you migrate your TensorFlow models to PyTorch seamlessly.

Key Steps:

  1. Export TensorFlow Model
    Use tf.saved_model.save() to save your model in .pb format or tf.keras to export in .h5 format.
    📌 Example:

    tf.saved_model.save(model, 'tf_model')  
    
  2. Convert to ONNX Format
    Convert the TensorFlow model to ONNX using tf2onnx tool.
    🛠️ Command:

    python -m tf2onnx.convert --saved-model tf_model --output model.onnx  
    
  3. Load ONNX in PyTorch
    Use torch.onnx module to load the model and restructure it in PyTorch.
    🧩 Code snippet:

    import torch  
    model = torch.jit.load("model.onnx")  
    
  4. Fine-tune in PyTorch
    Adjust hyperparameters and train the model using PyTorch’s training loop.
