Hello all,
I am getting the following error when I use the SquaredL2Distance operator as the output layer of my CNN network (1st attempt):
dist = model.net.SquaredL2Distance([label, fc9_], 'dist')
predictions = dist.AveragedLoss([], ['predictions'])

Then I tried to fix the error converting label to float (even though it is already float32, see below) using the Cast operator (2nd attempt)
label_float = model.Cast(label, None, to=core.DataType.FLOAT)
dist = model.net.SquaredL2Distance([label_float, fc9_], 'dist')
predictions = dist.AveragedLoss([], ['predictions'])
However, I got the following error:

Furthermore, I created the LMDB training dataset which stores the image data as uint8 and the label as a multivalue of float64:
key: 00000001
image_data: shape: (210, 280, 3) type: uint8
indicators: shape: (14,) type: float64
How can I fix the error???
