Can you help me setting environment variables? about tch-rs HOT 2 OPEN

I only set two variables like this

export LIBTORCH=/home/test/libtorch
export LD_LIBRARY_PATH=/home/test/libtorch/lib/:$LD_LIBRARY_PATH

and it works.

from tch-rs.

for me it was an extra "include" and "torch" if you have a trailing one
export LIBTORCH_INCLUDE=/home/bion/hax/externals/pytorch/torch/csrc/api
no trailing /include because the build.rs might add that path part again non-idempotently

for autograd stuff, the issue could be they are in separate areas of the torch directory tree

(py310) [2024-05-24T08:29:36-0400]
~/hax/externals/pytorch/torch (main) $

fd engine.h
csrc/autograd/engine.h
csrc/autograd/python_engine.h
csrc/distributed/autograd/engine/dist_engine.h
(py310) [2024-05-24T08:29:46-0400]
~/hax/externals/pytorch/torch (main) $
fd torch.h
csrc/api/include/torch/torch.h

if we only "include" /api/include/ then we're missing the /autograd/

sadly the build script isn't working right now with latest pytorch i guess, this line linked above might need to also include the

/pytorch/torch/csrc/autograd/

ugh i could try it locally

from tch-rs.
