Python: TypeError: Only 2-D and 3-D images supported with scikit-image regionprops
<p>Given a <code>numpy.ndarray</code> of the kind</p>

<pre><code>myarray= 
array([1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 1, 1])
</code></pre>

<p>I want to use <code>scikit-image</code> on the array (which is already labelled) to derive some properties.</p>

<p>This is what I do:</p>

<pre><code>myarray.reshape((11,11))                  
labelled=label(myarray)
props=sk.measure.regionprops(labelled)
</code></pre>

<p>But then I get this error:
<code>TypeError: Only 2-D and 3-D images supported.</code>, pointing at <code>props</code>. <strong>What is the problem? The image I am passing to <code>props</code> is already a 2D object.</strong></p>

<p>Shape of <code>myarray</code>:</p>

<pre><code>In [17]: myarray
