CNTK 2.1 + keras example deep_dream.py

[pmfcdb]

Hi,

When I try to run this example "deep_dream.py" from :

https://github.com/fchollet/keras/tree/master/examples

I get this error:

Variable 'Constant('_keras_learning_phase', [], [])' SetValue(): 'source' shape '[1]' differs 'destination' shape '[]'. [CALL STACK]

@pmfcdb just change "v = np.float32([value])" -> "v = np.array(np.float32(value))" in your keras\backend\cntk_backend.py.

def set_learning_phase(value):
    global _LEARNING_PHASE
    if value not in {0, 1}:
        raise ValueError('CNTK Backend: Set learning phase '
                         'with value %s is not supported, '
                         'expected 0 or 1.' % value)
    #v = np.float32([value])
    v = np.array(np.float32(value))
    _LEARNING_PHASE.value = v

Hi, thks, it worked, but now I get this error:
