Gotcha 2: Context Switches

The Cost of Data Transitions:

• Orchestrating compiled code necessitates translating data between high-level Python objects and low-level data structures (C/C++).

• Element-wise transitions are computationally expensive and consume considerable memory.

• Poor transition management is a primary cause of performance degradation when utilizing libraries like numpy or pytorch.

Example Bottleneck:

Iterating over a compiled array (e.g., a NumPy array) with a native Python loop forces continuous, costly data conversion.
