tensorboadX display image error

I use tensorboardX.SummaryWriter.add_image to display some feature maps, but it will regard some negative number as positive and display confusion.
For example:
individualImage

that image is a feature map, it have some irregular bright shots and some regular bright circles. Actually, the irregular shot are negtive and less than regular shot, but it looks so bright. Are there some bugs in tensorboardX?

Did you normalize images?

You are right. I didn’t normalize the feature maps. I think tensorboardX will normalize it, but it not.
