title: ValueError: Cannot feed value of shape (261, 25088) for Tensor 'Placeholder_26:0', which has shape '(?, 30)'
body: <p>i am trying to classify my images features by loading bottleneck_features_train.npy, i do not now what is the Nº of inputs in D variable that's suits my data with shape (261, 25088.
  here is my code</p>
  <pre><code>dataset1 = np.load('bottleneck_features_train.npy', encoding='bytes')
  nsamples, nx, ny, nz = dataset1.shape
  X = dataset1.reshape((nsamples,nx*ny*nz))
  Y = generator.classes
  Y = to_categorical(Y)
  Y = np.argmax(Y, axis=1)
  seed = 9
  X_train, X_val,Y_train, Y_val = train_test_split(X,Y,test_size=0.2, random_state=seed)
  
  D          = ??
  m          = 16    # Rules
  alpha      =  0.01 # Training rate
  num_epochs = 600   # Nº of epochs
  fis = ANFIS(n_inputs=D, n_rules=m, learning_rate=alpha)
  </code></pre>
  <p>i got the following error</p>
  <p>ValueError: Cannot feed value of shape (261, 25088) for Tensor 'Placeholder_26:0', which has shape '(?, 30)'</p>
