OverflowError: Range exceeds valid bounds

[jagiella]

I just transfered my scripts to a different machine (both Ubuntu 16.04) and the error (see Issue title) popped up. On my old machine it is working flawlessly.

My code causing the problem:

model = Sequential()

model.add(Convolution2D(nb_conv_filters, conv_kernel_size, conv_kernel_size, border_mode='valid', input_shape=(1, img_rows, img_cols)))
model.add(Activation('relu'))
model.add(MaxPooling2D(pool_size=(pool_kernel_size, pool_kernel_size)))

model.add(Flatten())

model.add(Dense(nb_dense_neurons)) #128
model.add(Activation('relu'))
model.add(Dropout(0.5))

model.add(Dense(nb_classes))
model.add(Activation('softmax'))

model.compile(loss='categorical_crossentropy',
                  optimizer='adadelta',
                  metrics=['accuracy'])

The error is the following:

OverflowError: Range exceeds valid bounds

Any idea what causes this problem and how to get rid of it? It seems to occure while adding a dense layer.

Same problem with me and others

[Viveksbawa]

I am facing the same problem. the networked which were working perfect on ubuntu 14 are generating error "OverflowError: Range exceeds valid bounds" in ubuntu 16. issue is with dense layer. can't figure out the problem. please share if anyone has resolved this issue.

I had the same problem using the same code but updating the system. I solved the problem adding these two lines at the beginning of the code:

from keras import backend as K
K.set_image_dim_ordering('th')

Hope can help

@Simmetria0 it works for me! thanks!

@Simmetria0 it also works for me. Thank you.
