Applications for gradient Halide

Dependencies

• pytorch
• py.test
• halide

Building

Set the HALIDE_DIR env var to your Halide root directory. Then run:

cd gapps
make

Adding a new operator

See 'dummy' for an example. This is done in 5 steps:

1. Write a Halide generator e.g. src/dummy.hl.cxx.

2. Declare a CFFI entry point in src/operators.h.

3. Write the PyTorch C interface in src/operator.cxx.

4. Register your new operator with Autograd in functions/operators.py.

5. Add an entry in the Makefile (under OPS)

Running tests

Run with stdout prints:

cd gapps py.test --capture=no test

Visdom

python3 -m visdom.server
