Float input values for RandomGamma

[zahragolpa]

🐛 Bug

I get an error when I run RandomGamma transform with a float gamma_limit value.

To Reproduce

Steps to reproduce the behavior:

1. Run RandomGamma with a float gamma_limit value.

import albumentations as A
import cv2

input_image_numpy = cv2.imread(PATH_TO_INPUT_IMAGE)
transform = A.Compose([A.RandomGamma(gamma_limit=(80.8, 120.2), p=1)])
transformed = transform(image=input_image_numpy)
transformed_image = transformed["image"]
cv2.imwrite('output.png', transformed_image)

The error I get:

ValueError: non-integer arg 1 for randrange()

Expected behavior

Should produce the output image even when input is float, as stated in the documentation.

Environment

• Albumentations version: albumentations==1.1.0
• Python version: Python 3.8.8
• OS: macOS
