Tensorflow: concatenating 2 tensors of shapes containing None
Before asking a question I should probably try to run the code :) Using tf.concat(values=[A, B], concat_dim=3) seems to be working.
My problem is the following: I have a tensor A of shape [None, None, None, 3] ([batch_size, height, width, num_channels]) and a tensor B. At runtime it is guaranteed that A and B will have the same shape. I would like to concatenate these two tensors along num_channels axis.
PS. Note that I simplified my original problem - so having a tensor of shape [None, None, None, 6] in the first place is not an option.
