Lighting in the get_transform()

Here is my ImageDataBunch generator code:

data = ImageDataBunch.from_csv(path, ds_tfms=get_transforms(max_lighting=None, p_lighting=0.0), valid_pct=0.2, size=(256, 192), bs=16).normalize(imagenet_stats)

When I am plotting the top_losses plot I am getting the following (a snap):

If I am not wrong the lightning is disabled in the first place while creating the ImageDataBunch. But why there is this lighting? Of course, the original data does not have any.

@Sayak Are you talking about heat maps???

@shivu not at all.

Edit: @shivu my bad, I was not aware of the heatmap parameter in the plot_top_losses() method.

Had same problem here, it is heatmap parameter.

Thank you @sheepish
