mo.utils.error.Error: 'TensorProto' object has no attribute 'uint8_val'


I am trying to convert the tensorflow ICNet model using the following command,

python --input_meta_graph model.ckpt-0.meta --data_type FP16 --log=DEBUG

It generates the following error

[ ERROR ]  'TensorProto' object has no attribute 'uint8_val'
Unexpected exception happened during extracting attributes for node Reshape_1.
Original exception message: 'TensorProto' object has no attribute 'uint8_val'

Please advise .Thanks.
