Hi,
I met this problem when I training the model:
Traceback (most recent call last):
File "./src/retinaNN_training.py", line 107, in
model = get_unet(n_ch, patch_height, patch_width) #the U-net model
File "./src/retinaNN_training.py", line 48, in get_unet
up1 = merge([UpSampling2D(size=(2, 2))(conv3), conv2], mode='concat', concat_axis=1)
File "/usr/local/lib/python2.7/dist-packages/Keras-1.1.2-py2.7.egg/keras/engine/topology.py", line 1539, in merge
name=name)
File "/usr/local/lib/python2.7/dist-packages/Keras-1.1.2-py2.7.egg/keras/engine/topology.py", line 1170, in init
node_indices, tensor_indices)
File "/usr/local/lib/python2.7/dist-packages/Keras-1.1.2-py2.7.egg/keras/engine/topology.py", line 1237, in _arguments_validation
'Layer shapes: %s' % (input_shapes))
Exception: "concat" mode can only merge layers with matching output shapes except for the concat axis. Layer shapes: [(None, 0, 24, 128), (None, 0, 24, 64)]
I don't know how to fix it. I'm new to keras, could you please to help me?
Thank you for reading my question.
I found the right way to solve the problem just as Filter size error #6 said: change "tf" in "image_dim_ordering" to "th", and the training works fine.
