title: Error while trying to save .npy (numpy) file
body: <p>c:\python38\lib\site-packages\numpy\core_asarray.py:136: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray
  return array(a, dtype, copy=False, order=order, subok=True)</p>
  <p>I have gone through some questions in the stackoverflow so tried to upgrade scipy for this but it shows another error:</p>
  <p>ERROR: tensorflow 2.2.0 has requirement scipy==1.4.1; python_version &gt;= &quot;3&quot;, but you'll have scipy 1.5.0 which is incompatible.</p>
  <p>can someone tell why is this happening?</p>
