pytorch albumentations augmentation p value?
augmented_images(raw.image_id.unique()[1230], albumentations.HorizontalFlip(p=1))

for augmented_image what is the p=1 mean? is value difference make angle different?
if its not it how should I make various angle different horizontal augmentation?

As you can see in the docs of albumentations.HorizontalFlip:

Parameters:   p (float) – probability of applying the transform. Default: 0.5.

If you want to rotate, you should consider using albumentations.augmentations.transforms.Rotate:

Rotate(limit=90, interpolation=1, border_mode=4, value=None, mask_value=None, always_apply=False, p=0.5)
Rotate the input by an angle selected randomly from the uniform distribution.
Parameters:

limit ((int, int) or int) – range from which a random angle is picked. If limit is a single int an angle is picked from (-limit, limit). Default: (-90, 90)
[...]
p (float) – probability of applying the transform. Default: 0.5.
