Clipping input data to the valid range for imshow with RGB data ([0..1] for floats or [0..255] for integers).

This warning message is usually displayed when we try to display an image using the `imshow` function in Matplotlib, but the pixel values of the image are outside the valid range of [0, 1] for floating-point values or [0, 255] for integer values.
To fix this, we can normalize the pixel values of the image to fall within the valid range using either of the following methods:
1. If the pixel values are integer values ranging from 0 to 255, we can divide them by 255 to normalize them to the range [0, 1]. For example:
```
img_normalized = img.astype('float32') / 255.0
plt.imshow(img_normalized)
```
2. If the pixel values are floating-point values outside the range [0, 1], we can clip them to the range [0, 1] using the `np.clip()` function. For example:
```
img_clipped = np.clip(img, 0, 1)
plt.imshow(img_clipped)
```
By normalizing the pixel values of the image, we can avoid the warning message and correctly display the image using `imshow`.
