fixed after pip --upgrade scikit-neuralnetwork

alexjc commented 9 years ago

This needs to be fixed in the master branch, you just downgraded. Here's the workaround:

from sknn.backend import pylearn2

Also needs some documentation, I will leave this open as a reference until it's fixed in 0.3.

I am getting this error when I try to build a single AutoEncoder. Lasagne built correctly with sknn during the pip install, but I am still getting this error. Any thoughts on how to fix it? I am using Ubuntu 14.04.

alexjc commented 8 years ago

There is no auto-encoder implemented in the latest release for Lasagne. #129

You need to go back to 0.4 for the PyLearn2 version, but that backend is not very well maintained and had many bugs.

tgsmith61591 commented 7 years ago

So, is there any plan to tie the current AutoEncoder into any backend, or is it going to just be unusable for the forseeable future?
