2.torch to onnx

import torch

torch.onnx.export(model=,
				  args=,
				  f=,
				  input_names=,
				  output_names=)

3.onnx to tensorflow

import onnx
import onnx_tf

model = onnx.load(file_path)
tf_export = onnx_tf.prepare(model)
tf_export.export_graph('XXX.pb')

4.use onnx to infer

import onnxruntime

sess = onnxruntime.InferenceSession('XXX.onnx')
inputs_name = sess.get_inputs[0].name
outputs_name = sess.get_outputs[0].name

results = sess.run([], {'input1': [array format]})
