I want to store numpy array into to another numpy array

I am using `np.concatenate`

This is my code

```
x=np.concatenate(x,s_x)
```

These are the type and the shape of `x and s_x`

```
Type of s_x: <class 'numpy.ndarray'>, Shape of s_x: (173,)
Type of x: <class 'numpy.ndarray'> (0,), Shape of x: (0,)
```

This is the error being displayed

```
TypeError: only integer scalar arrays can be converted to a scalar index
```
