if it's a zero initializer, then we can remove the subgraph, for onnx treats it as zero if the input is not supported.

Hi, I tried to convert an LSTM model from TF to ONNX, part of the code related to LSTM is as below: ``` keep_prob = tf.constant(1.0) #tf.placeholder(tf.float32,name="keepProb") h_fc1_drop = tf.nn.dropout(h_fc1,...
