@carette I created a docker image with maple builtin for reproducing the issue me and @ccshan were having. To use it download https://drive.google.com/file/d/10ieuJjtKazLlmBKG38n72lvLZlVNRypy/view?usp=sharing it is a 3GB file with everything inside it. Commands to make it run: docker import hakaru-docker.tar.gz hakaru docker run --entrypoint "/init.sh" --mac-address 1c:1b:0d:e3:fc:22 -it hakaru hakaru-benchmarks is in /hakaru-benchmarks and maple is installed in /hakaru-benchmarks/maple2017 to reproduce the maple issue cd /hakaru-benchmarks/testcode/hssrc/ make make will only run GmmGibbs simplification as I only deleted that file.
