When using only 1 worker (instead of 2), the test run, but eventually gives:
[INFO 02-16 07:48:13] optimas.generators.base: Generated trial 79 with parameters {'x0': 0.1001368227796458, 'x1': 2.940237902665191}

AssertionError: alloc_f did not return any work, although all workers are idle.
I looked more closely at the error with 2 workers, here is the log:
[INFO 02-16 07:54:38] optimas.generators.base: Generated trial 0 with parameters {'x0': -1.0, 'x1': 3.5}

and then

AssertionError
so it looks like the error is not when calling generate
several times (this simply returned the same point), but rather when calling add_data
several times (without calling generate
in-between`).
This is superseded by https://github.com/optimas-org/optimas/pull/228
