i finished install caffe and python interface, but i failed to load a pretrained caffe model.

``` python
net = caffe.Classifier('tmp.prototxt', param_fn,
mean = np.float32([104.0, 116.0, 122.0]),
channel_swap = (2,1,0))

caffe\python\caffe\classifier.pyc in __init__(self, model_file, pretrained_file, image_dims, mean, input_scale, raw_scale, channel_swap)
27
28 # configure pre-processing
---> 29 in_ = self.inputs[0]
30 self.transformer = caffe.io.Transformer(
31 {in_: self.blobs[in_].data.shape})

AttributeError: 'Classifier' object has no attribute 'inputs'
