title: TypeError: cannot unpack non-iterable int objec
body: <p>how can I solve this error After running my code as follows . I am using the function below and implementin running window for loop on it but end up getting the error below. The for loop works and hungs at a point.</p>
  <pre><code>def get_grps(s, thresh=-1, Nmin=3):
