I’m trying to get LibTorch running on an aarch64 computer. Namely a Jetson AGX Xavier.
I built it by downloading the PyTorch repo and running ‘python3 tools/build_libtorch.py’
It took hours to ‘build libtorch’ and then I ran the example script from the official LibTorch site.
The first time I created a build folder, and ran cmake -DCMAKE_PREFIX_PATH=/home/jet/pytorch/ … then cmake --build . --config Release
it seemed like it built with no errors, but since that one time it worked I’ve been getting the following error…
This is the error I get now when I run cmake -DCMAKE_PREFIX_PATH=/home/jet/pytorch/ …
$ cmake -DCMAKE_PREFIX_PATH=/home/jet/pytorch/ …
