Why should I use keras.ops instead of torch or numpy?

Using keras.ops ensures your code is backend-agnostic, allowing it to run seamlessly on PyTorch, JAX, or TensorFlow without modification, which is essential for the BayesFlow ecosystem.

Can I still use backend-specific features like CUDA cache clearing?

Yes, the skill includes guidance on using backend-specific code guards that allow you to call features like torch.cuda.empty_cache() without breaking non-PyTorch backends.

How does this skill handle gradient stopping?

It provides patterns using keras.ops.stop_gradient to cut gradients on sampling paths, which is a critical optimization for saving activation memory during log-probability evaluations.

How do I convert NumPy arrays to Keras tensors safely?

Use the keras.ops.convert_to_tensor() function at the boundary where data enters your Keras compute path to ensure proper type handling and backend compatibility.

Standardizes tensor mathematics for BayesFlow extensions using Keras 3's backend-agnostic operations to ensure compatibility across PyTorch, JAX, and TensorFlow.

This skill provides a specialized framework for writing portable tensor math within the BayesFlow ecosystem. By enforcing the use of Keras 3 ops instead of backend-specific libraries like PyTorch, JAX, or NumPy, it ensures that custom layers, loss functions, and network forward passes remain compatible regardless of the underlying computational engine. It includes optimized patterns for detached sampling, memory-efficient chunking, and straight-through estimators, helping developers avoid common pitfalls such as backend-specific API leaks or unintended gradient flow issues.
