Does MorphNet support conv3d?

Hi,

I'm applying MorphNet on tf.contrib.layers.conv3d(), but it seems that no ops are found.
`INFO:tensorflow:OpRegularizerManager starting analysis from: [].`
`INFO:tensorflow:OpRegularizerManager found 46 ops and 0 sources.`
`INFO:tensorflow:OpRegularizerManager regularizing 0 groups.`
`WARNING:tensorflow:No supported ops found.`

Here is my code:
`imgs = tf.placeholder(tf.float32, (4, 8, 24, 24, 3))`
`net = tf.contrib.layers.conv3d(imgs, num_outputs=64, kernel_size=7, name='conv1')`
`net = tf.nn.max_pool3d(net, [1, 2, 2, 2, 1], [1, 2, 2, 2, 1], padding='VALID', name='maxpool1')`
`net = tf.contrib.layers.batch_norm(net, center=True, scale=True, is_training=True, scope='bn1')`
`logits = tf.contrib.layers.fully_connected(net, 10, scope='fc')`
`network_regularizer = model_size_regularizer.GammaModelSizeRegularizer([logits.op], gamma_threshold=1e-3)`
`regularization_strength = ....`

Does MorphNet support 3d convolution? Thanks!
