dynasor.logging_tools.set_logging_level(level)

Alters the logging verbosity logging is handled.

Possible values from least to most verbose: CRITICAL, ERROR, WARNING, INFO, DEBUG.

level (str) – Verbosity level; see Python logging library for details.

Return type:

None

dynasor.logging_tools.warn_if_numba_threading_layer_is_slow()

Emit a one-time warning if Numba has fallen back to the workqueue threading layer, which is available everywhere but not tuned for performance; installing TBB (pip install tbb) lets Numba pick a faster, fork-safe layer instead.

Numba only selects its threading layer lazily, the first time a parallel (@numba.njit(parallel=True)) kernel actually runs, so this is a no-op until that has happened at least once; call it right after such a kernel has run.

Return type:

None
