New User - NUTS Running forever on regression tutorial

Two things to try in a notebook:

  1. Specify the multiprocessing context to use. This came up in this thread . Check the docs for pm.sample for all the mp_ctx options.
idata = pm.sample(chains=4, draws=2000, random_seed=RANDOM_SEED, mp_ctx='spawn')
  1. Compile to numba instead of C, to rule out annoying BLAS things. It shouldn’t be an issue in this model (no matrix multiplications), but I’m constantly surprised at how wrong my assumptions can be:
idata = pm.sample(chains=4, draws=2000, random_seed=RANDOM_SEED, compile_kwargs={'mode':'NUMBA'})
