Triton is a fairly self-contained package and uses its own parser (forked from wgtcc) and LLVM-8.0+ for code generation.
sudo apt-get install llvm-8-dev git clone https://github.com/ptillet/triton.git; cd triton/python/; python setup.py develop;
This should take about 15-20 seconds to compile on a modern machine.
You can then test your installation by running the einsum.py example in an environment that contains pytorch:
cd examples; python einsum.py
