A Major Limitation of NumPy Which Most Users Aren't Aware Of

..and here's how to address it.

NumPy undoubtedly offers

  • extremely fast, and

  • optimized operations.

Yet, it DOES NOT support parallelism.

This provides further scope for run-time improvement.

Numexpr is a fast evaluator for NumPy expression, which uses:

  • multi-threading

  • just-in-time compilation

The speedup offered by Numexpr is evident from the image above.

Depending upon the complexity of the expression, the speed-ups can range from 0.95x and 20x.
