when I run the LUNA_train_unet.py, I get an error.

[eshinesimida]

run the codes:
up6 = merge([UpSampling2D(size=(2, 2))(conv5), conv4], mode='concat', concat_axis=1)
conv6 = Convolution2D(256, 3, 3, activation='relu', border_mode='same')(up6)
conv6 = Convolution2D(256, 3, 3, activation='relu', border_mode='same')(conv6)

I get an error:
up6 = merge([UpSampling2D(size=(2, 2))(conv5), conv4], mode='concat', concat_axis=1)
conv6 = Convolution2D(256, 3, 3, activation='relu', border_mode='same')(up6)
conv6 = Convolution2D(256, 3, 3, activation='relu', border_mode='same')(conv6)

could you help me. thank you

Possible solution here

[wushuo1997]

you could try' pip install keras==2.1.2'
since there is not a merge function in keras 2.2.4
and it works for me.
good luck

@wushuo1997 Hi!Did you run classify_nodes.py successfully ?
I run this successfully ,but It's all 0 in dataY.npy. Why is there no 1?
