could not broadcast input array from shape (2) into shape (1,35)

This error message indicates that there is a mismatch between the dimensions of two arrays that you are trying to merge or broadcast together. Specifically, you are trying to broadcast an array with shape (2) onto an array with shape (1, 35), which is not possible.
To resolve this error, you will need to reshape or resize one or both of the arrays so that they have compatible shapes. One approach might be to reshape the (2) array to have shape (1, 2) using the np.reshape() function, and then broadcast it onto the (1, 35) array.
For example:
```
import numpy as np
a = np.array([1, 2])
b = np.zeros((1, 35))
a_reshaped = np.reshape(a, (1, 2))
b[:a_reshaped.shape[0], :a_reshaped.shape[1]] += a_reshaped
print(b)
```
This code reshapes the (2) array to have shape (1, 2), and then adds it to the (1, 35) array using array indexing. The resulting output should be a (1, 35) array with the first two elements set to the values of the (2) array.
