When i try to use the **freezeTrainedBert.py** to **freeze the graph** , i choose the node name : **loss/SparseSoftmaxCrossEntropyWithLogits/SparseSoftmaxCrossEntropyWithLogits** , but i got follow exception:

thanks so much.

@Maple that looks like a disconnected node found during import. Make sure the node has inputs and that every node has a constant or placeholder associated with it in the graph.

the nodes has inputs, and the model can be fine tuned correctly. i tried another way.for example:

i choose this node,“loss/Softmax”, in BertInferenceExample, it choose this too.and i can froze the graph to pb, like this:

but i run it in BertInferenceExample, it goes Exception.
