Image data of dtype <U10 cannot be converted to float

This error occurs when you try to convert image data of type string (`<U10`) to float type. This conversion is not possible as the string data cannot be interpreted as a numerical value.
To resolve this error, you need to convert the image data to the correct data type before performing any mathematical operations on it. You can use the `astype()` method to convert the data type of the image array. For example, if you want to convert the image data to `float32`, you can use the following code:
```python
import numpy as np
from PIL import Image
# Load image
img = Image.open('image.jpg')
# Convert image to numpy array
img_arr = np.array(img)
# Convert data type of image array to float32
img_arr = img_arr.astype('float32')
```
This will convert the data type of the image array to `float32`, allowing you to perform mathematical operations on it without encountering the `dtype <U10 cannot be converted to float` error.
