Hi all, thought I'd share this in case anyone is using newer AMD hardware. Apparently Intel's MKL library runs a hardware check, and by default will prevent the AVX2 unit on AMD processors from functioning. For a detailed example of the speedup in some workflows, see here.
On linux, the workaround is quite simple, set the environment variable below. Note that intel may disable this debug command in the future, but for now it works really well.
