Confusion about the to_rgb flag in mmlabNormalize function

[zhanghm1995]

Hello, thanks for sharing this wonderful work.

When I dive into this code, I am curious about the image processing pipeline. In this line, you load the images with the PIL.Image.open function, in this case, the channels order of the images are already RGB.

However, you still use the to_rgb = True in this line in the mmlabNormalize function to transform the order of the channels. But in this case, the channels would be changed to BGR.

I'm not sure if this operation is your special design or just a bug. I hope you could help me to understand this.
