Convert model to ONNX format

Hello, I'm trying to convert .pb model to Onnx format. But there was an error.

Command:

python -m tf2onnx.convert --input 20180402-114759.pb--inputs input:0,phase_train:0 --outputs embeddings:0 --output model_2311.onnx --verbose

Error:

ValueError: NodeDef expected inputs '' do not match 1 inputs specified; Op<name=Const; signature= -> output:dtype; attr=value:tensor; attr=dtype:type>; NodeDef: {{node InceptionResnetV1/Conv2d_1a_3x3/BatchNorm/cond/Const}} = Const[dtype=DT_FLOAT, value=Tensor<type: float shape: [0] values: >](InceptionResnetV1/Conv2d_1a_3x3/BatchNorm/cond/Switch:1)

Thank!
