### Model Description
We provide example code in [models](https://github.com/megengine/models/official/nlp/bert).
This example code fine-tunes the pre-trained `uncased_L-12_H-768_A-12` model on the Microsoft Research Paraphrase (MRPC) dataset.
This example code fine-tunes the pre-trained `uncased_L-12_H-768_A-12` model on the Microsoft Research Paraphrase (MRPC) dataset.
Our test ran on the original implementation hyper-parameters gave evaluation results between 84% and 88%.

All pre-trained models expect input images normalized in the same way. Input images must be 3-channel BGR images of shape (H x W x 3), reszied to (512 x 512), then normalized using mean = [103.530, 116.280, 123.675] and std = [57.375, 57.120, 58.395]).
Here's a sample execution.
