title: Memory error In instantiating the numpy array
body: <p>I have a list <strong>A</strong> of a 50,000 elements and each element is an array of shape (102400) </p>
  
  <p>I tried instantiating an array <strong>B</strong>.</p>
  
  <pre><code>     B=numpy.array(A)
  </code></pre>
  
  <p>But this throws an exception MemoryError.I know that the memory and size is very huge?But is there a way to avoid this MemoryError with ndarrays in numpy ??</p>
