title: Failed to find data adapter that can handle input:...(list to numpy array with given dimensions)
body: <p>I have a list X in python which contains 20000 images of dimension (100,100,3) each. Each of the images is of type numpy.ndarray. I wish to input this list of images as the training vector for a CNN model using model.fit(X) in Tensorflow. However doing so gives me the following error:</p>
  <p><code>ValueError: Failed to find data adapter that can handle input: (&lt;class 'list'&gt; containing values of types {&quot;&lt;class 'numpy.ndarray'&gt;&quot;}), (&lt;class 'list'&gt; containing values of types {&quot;&lt;class 'numpy.int64'&gt;&quot;})</code></p>
  <p>Would converting list X into a numpy.ndarray of dimensions (20000,100,100,3) help?</p>
  <p>If yes, how can I do that?</p>
  <p>If not, could you please suggest what can be done?</p>
