This repo (finn-base) is scheduled to be deprecated soon, and should be replaced in any dependent projects with the new QONNX (https://github.com/fastmachinelearning/qonnx) repo. QONNX is nearly a drop-in replacement for finn-base, only a namespace change is needed (e.g. import finn.core.modelwrapper becomes import qonnx.core.modelwrapper).
finn-base is part of the FINN project and provides the core infrastructure for the FINN compiler, including:
- wrapper around ONNX models for easier manipulation
- infrastructure for applying transformation and analysis passes on ONNX graphs
- infrastructure for defining and executing custom ONNX ops (for verification and code generation)
- extensions to ONNX models using annotations, including few-bit data types, sparsity and data layout specifiers
- several transformation passes, including topological sorting, constant folding and convolution lowering
- several custom ops including im2col and multi-thresholding for quantized activations
- several utility functions, including packing for few-bit integers
finn-base can be installed via pip by following these instructions.
