Use ESRGAN (old Architecture) weights

[Klanly]

I made a google colab script to convert ESRGAN (old Architecture) pth files to .param and .bin:

import shutil
import os
!7z x '/content/drive/My Drive/TFMLz/ESRGAN_oldarch/ncnnconv.7z' -o/content
!apt-get install -y libomp-dev
!pip install onnx-simplifier
!chmod u+x onnx2ncnn
!chmod u+x ncnnoptimize
adst='/content/esr.pth'

'''
asrc='/content/drive/My Drive/TFMLz/ESRGAN_oldarch/models/FatalimiX.pth'
shutil.copyfile(asrc,adst)
'''
'''
!7z e '/content/drive/My Drive/TFMLz/ESRGAN_oldarch/models/falcoon300.7z' -o/content
ren xxx.pth esr.pth
...


!python to_onnx.py
!python -m onnxsim '/content/esr.onnx' '/content/esr_simp.onnx'
!/content/onnx2ncnn /content/esr_simp.onnx /content/x4_o1.param /content/x4_o1.bin
!/content/ncnnoptimize /content/x4_o1.param /content/x4_o1.bin /content/x4_fp32.param /content/x4_fp32.bin 0
!/content/ncnnoptimize /content/x4_o1.param /content/x4_o1.bin /content/x4_fp16.param /content/x4_fp16.bin 1

ncnnconv.zip, rename it to .7z
(to_onnx.py .etc from github.com/achie27/super-resolution )

Replace 'models-DF2K/x4.bin' with the generated x4_fp32.bin or x4_fp16.bin then that's it.

There are about +-3 value bias per channel, comparing to it's original pytorch results.

Could you just share the bin files instead of pointing to the Colab script?
Also those file paths for the drive should be not working for other users I think

This the converted weights& prog I currently use..
https://github.com/Klanly/lunusbuild/releases/download/gcgghq/SR.zip

1x ( cmd: realsr.exe -m c -s 1 ) is "Fatality DeBlur";
4x ( cmd: realsr.exe -m c ) is "FatalimiX".

Weights form:

default input = tibr_o.jpg
default output = output.png

@Klanly
How can you specify a different model?
Something like realrsr.exe -m "DF2K_JPEG" (if the folder is named that way) doesn't seem to work
And what does -m c do?

https://github.com/Klanly/realsr-ncnn-vulkan/blob/master/src/Readme/Readme.md
'a'=models-DF2K_JPEG, 'b'=models-DF2K, 'c'=models-ESRGAN

So,
-m a = -m "DF2K_JPEG"
-m b = -m "DF2K"
