详细解释一下np.average的用法

Sure, np.average is a function in the NumPy library that computes the average (also known as mean) of an array or sequence. It takes two arguments: the first argument is the array or sequence that we want to compute the average of, and the second argument is optional and specifies the weights that should be assigned to each value in the array or sequence. If no weights are specified, all values are assumed to have equal weight.
For example:
```
import numpy as np
x = np.array([1, 2, 3, 4, 5])
avg = np.average(x)
print(avg) # Output: 3.0
```
In this example, we create an array with five values and compute the average using np.average. Since we did not specify any weights, np.average assumes that each value has equal weight and simply computes the arithmetic mean.
I hope that helps!
