ValueError: operands could not be broadcast together with shape (2400,) (2,)

This error occurs when trying to perform an operation on two arrays with incompatible shapes. In this case, the first array has a shape of (2400,) and the second array has a shape of (2,).
To fix this error, you need to make sure that the shapes of the two arrays are compatible for the operation you are trying to perform. You can reshape one or both of the arrays to match the desired shape, or you can use broadcasting to perform the operation.
For example, if you want to add the two arrays element-wise, you can reshape the second array to have the same shape as the first array:
```
import numpy as np
a = np.random.rand(2400)
b = np.array([1, 2])
b = np.tile(b, 1200) # repeat b 1200 times to match the shape of a
c = a + b
```
Alternatively, you can use broadcasting to add the second array to each element of the first array:
```
import numpy as np
a = np.random.rand(2400)
b = np.array([1, 2])
c = a + b[:, np.newaxis] # add b to each element of a
```
In this case, broadcasting automatically expands the second array to have the same shape as the first array, allowing the addition to be performed element-wise.
