I encountered the same issue. It also occurs when using an ImagePlayerIterator
with the spatial dimensions of window_shape
set to the kernel size of the first convolutional layer. In that case, conv_count
will yield zero for the patch currently masked out, because the shape of the masked elements exactly matches that of the kernel size.
I'm not sure whether the fix proposed by @GlowingHorse would work. When taking the maximum, wouldn't conv_count
always be the kernel size, disregarding the actual mask?

Seems like some zero padding makes the output conv_count
of the conv operation at zero.
-> dasp/layers/convolution.py
conv_count = self._conv2d(ghost, tf.ones_like(self.kernel))
I just add this
conv_count = tf.maximum(conv_count, tf.reduce_sum(tf.ones_like(self.kernel)))
after it. Is it same with your original thought?

Hi! It is still not clear to me how the result conv_count
can be zero because both the input (ghost
) and the kernel are made of ones.
EDIT: I did not see your mention to zero-padding. Your solution seems to make sense indeed.
