In SciPy 1.7.0 one of the most massive PRs in SciPy history was merged, scipy/scipy#10844. This PR added the scipy.stats.qmc submodule, which provides Quasi-Monte Carlo generators and associated helper functions. The qmc submodule is still developed and optimized.

It might be worth investigating if porting some of the EMAworkbench samplers (either the built-in samplers from samplers.py or the imported ones in salib_samplers.py). Sobol, Halton and LatinHypercube are likely candidates.
