**When parsing a .uff file from tensorflow model , one issue confused me , about tf.reshape():**

When I reshaped 2 tensors form (1,2,4,6) to (1,2,24), and add them, trt built the engine successfully

output_node_names = [“input”, “add”]

input = tf.placeholder(shape=[1,2,4,6],dtype=tf.float32, name=‘input’)

bias=tf.constant(value=1.0,shape=[1,2,4,6],dtype=tf.float32,name=‘bias’)

input=tf.reshape(input,shape=[1,2,24])

bias=tf.reshape(bias,shape=[1,2,24])

# node name:add

output=input+bias

But reshaped from (1,2,4,6) to (1,2,4,3,2), it failed: Parameter check failed at: Network.cpp::addScale::175, condition: shift.count == 0 || shift.count == weightCount

output_node_names = [“input”, “add”]

input = tf.placeholder(shape=[1,2,4,6],dtype=tf.float32, name=‘input’)

bias=tf.constant(value=1.0,shape=[1,2,4,6],dtype=tf.float32,name=‘bias’)

input=tf.reshape(input,shape=[1,2,4,3,2])

bias=tf.reshape(bias,shape=[1,2,4,3,2])

# node name:add

output=input+bias

It seemed not supported to add two tensors reshaped from less dimensions?
