NameError: global name 'btc01' is not defined

[Danfoa]

Using the voxnet.layers.Conv3dLayer I am getting this error:

line 120, in get_output_for out_btc01 = conv3d2d.conv3d(signals=btc01, filters=self.W, NameError: global name 'btc01' is not defined

I use normal implementation
in_layer = layers.InputLayer(shape=(None, 100, None, None, None), input_var=foo) num_filters = 100 conv3d_voxnet = voxnet.layers.Conv3dLayer(in_layer, num_filters=num_filters, filter_size=(1, 1, 1))

Indeed the variable btc01 is not defined, a few lines up you find input_btc01, i try renaming the first one to the second but I am getting now new errors.

PS: I haven't been able to use a single layer form this git, all of them through me errors and force me to change Theano and Lasagne versions all the time, i am a little disappointed.
