# Instructions on converting to NCNN models

1. Convert to onnx model with `scripts/pytorch2onnx.py`. Remember to modify codes accordingly
1. Convert onnx model to ncnn model
    1. `cd ncnn-master\ncnn\build\tools\onnx`
    1. `onnx2ncnn.exe realesrgan-x4.onnx realesrgan-x4-raw.param realesrgan-x4-raw.bin`
1. Optimize ncnn model
    1. fp16 mode
        1. `cd ncnn-master\ncnn\build\tools`
        1. `ncnnoptimize.exe realesrgan-x4-raw.param realesrgan-x4-raw.bin realesrgan-x4.param realesrgan-x4.bin 1`
1. Modify the blob name in `realesrgan-x4.param`: `data` and `output`
