Tensorflow: Valueerror wenn AdamOptimizer mit

Question

Wenn eine Sitzung in TensorFlow laufen bekomme ich folgende Fehler

optimizer = tf.train.AdamOptimizer(learning_rate=learning_rate).minimize(cost) 
File "/local0/software/python/python_bleeding_edge/lib/python2.7/site-packages/tensorflow/python/training/optimizer.py", line 190, in minimize

File "/local0/software/python/python_bleeding_edge/lib/python2.7/site-packages/tensorflow/python/ops/array_ops.py", line 982, in _DiagPartShape 
" do not match ") 
ValueError: Invalid shape, shape[:mid] (?,) and shape[mid:] (?,) do not match 

Ich bin nicht sicher, woher es kommt, da es keine Fehleranzeige im Modellbau nicht geben. Ich habe auch verschiedene Optimierer ausprobiert, z. GradientDescentOptimizer aber der Fehler bleibt bestehen.

Answer 1

Eigentlich ist Fehler irgendwie offensichtlich, wie die in dem Fehler

_DiagPartShape Invalid shape, shape[:mid] (?,) and shape[mid:] (?,) do not match 

Sie falsche Dimensionen zur Verfügung gestellt.
