 - To set a custom seed for the random number generator used by `ti.random()`: `ti.init(random_seed=seed)`. `seed` should be an integer. An example: `ti.init(random_seed=int(time.time()))`.
 - To set the default precision of floating-point numbers of Taichi runtime to `ti.f64`: `ti.init(default_fp=ti.i64)`.
 - To set the default precision of floating-point numbers of Taichi runtime to `ti.i32`: `ti.init(default_ip=ti.i32)`.
-- To enable the packed mode for memory layout: `ti.init(packed=True)`. See the [Packed mode](../basic/layout.md#packed-mode) for more information.
 - To disable the offline cache of compiled kernels: `ti.init(offline_cache=False)`. See the [Offline cache](../performance_tuning/performance.md#offline-cache) for more information.
 - To enable the use of variables as indices to access vector/matrix elements in the Taichi scope: `ti.init(dynamic_index=True)`.
 - To turn on kernel profiling: `ti.init(kernel_profiler=True)`. See the [Profiler](../performance_tuning/profiler.md#kernelprofiler) for more information.

 ## Logging
 
-- To set the logging level: `ti.init(log_level=ti.TRACE)` or  `ti.set_logging_level(ti.TRACE)` enables the TRACE level. The environment variable `TI_LOG_LEVEL` serves the same purpose.
+- To set the logging level: `ti.init(log_level=ti.TRACE)` or `ti.set_logging_level(ti.TRACE)` enables the TRACE level. The environment variable `TI_LOG_LEVEL` serves the same purpose.
