TypeError: Inkompatible übertragbare Dimensionen. Erwartet (Falsch), erhalten (True)

Question

Ich arbeite mit Theano und Lasagne.

Ich versuche, BatchNorm zu verwenden, und ich bekomme diesen Fehler. Kann mir bitte jemand sagen, was könnte falsch sein? Oder wenn ich den Namen der Variablen bekommen kann, die diese Abweichung hat?

Danke!

EDIT1:

Ich versuche, so etwas zu tun:

inputTarget = lasagne.layers.InputLayer(shape=(1,2,32, 32, 32), input_var=T.concatenate([tX, tY], axis=1)) 
network = lasagne.layers.SliceLayer(inputTarget, indices=slice(0, 1),axis=1) 
tX_new = lasagne.layers.get_output(network) 
network = lasagne.layers.batch_norm(network) 
tY_predicted = lasagne.layers.get_output(network) 
target= lasagne.layers.SliceLayer(inputTarget, indices=slice(1, None), axis=1) 

tY_new = lasagne.layers.get_output(target) 
loss = lasagne.objectives.squared_error(tY_predicted, tY_new).mean() 
updates = lasagne.updates.adam(loss, params, learning_rate=lr) 
train_fn = theano.function([tX, tY], [tY_predicted, loss, tY_new, tX_new], updates=updates) 

LOGS:

TypeError: Incompatible broadcastable dimensions. Expected (False,), got (True,). 

Nachdem die Variablen überprüft, weiß ich, dass die Code-Pausen für Mittelwert. Ich kann nicht herausfinden warum.

Theano macht keine Sendung, wie numpy (automatisch). Sie müssen die zu übertragende Dimension manuell festlegen. Es gibt ein erstaunliches Tutorial über das Senden von here. Wenn Ihr Problem nach dem Durchlaufen dieses Tutorials weiterhin besteht, teilen Sie mir bitte Ihren Code und das vollständige Traceback mit, damit ich Ihnen weiterhelfen kann.
