Description
Currently complex data type is not supported in ExecuTorch runtime. Although the model may be rewritten to real number operations, but it would affect the user's development efficiency.
What is complex data type here?
It's the math number system with real and imaginary parts like c = x * i * y.
It's used in some operations in PyTorch, like RoPE embedding in LLM, or Fourier Transforms (FFT).
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.

Research direction
The issue names no files, entry points, or tests. Start by locating ExecuTorch runtime handling for tensor data types and the relevant PyTorch operations, then determine the scope needed for complex tensors; done should include runtime support for the stated complex-number use cases and coverage showing they work.
