extract_features with mnist_autoencoder.prototxt

[Yingjun Li]

I want to extract the activation of encode4 layer. However, I get a 'Aborted' error. Can you please give me an idea about where the problem is?

Please see the below:

For this you need to use a 'deploy' version of the network prototxt. For further info look at my following answer in this thread: https://groups.google.com/d/msg/caffe-users/zBDa8kSlRR0/gzVUZjcBDAAJ
