AttributeError: 'module' object has no attribute 'io' in caffe
<p>I am trying to do a gender recognition program, below is the code..</p>

<pre><code>import caffe

gender_net = caffe.Classifier(gender_net_model_file,     gender_net_pretrained)

#Reshaping mean input image
mean_image = np.transpose(mean_image,(2,1,0))

#Gender labels

       rects = face_cascade.detectMultiScale(frame_gray, 1.3, 5)

       #Finding the largest face
       if len(rects) &gt;= 1:

<p>When I am running the I am getting an error: </p>

<pre><code>a = caffe.io.caffe_pb2.BlobProto.FromString(proto_data)
AttributeError: 'module' object has no attribute 'io'
</code></pre>

<p>How Can I solve it. I am using cnn_gender_age_prediction model. I want to make a real time gender recognition program using python and cnn_gender_age model.</p>
