Tensorflow 从onnx转.pb

首先需要安装onnx和onnx-tf这两个包，用pip安装就行

import onnx
from onnx_tf.backend import prepare

def onnx2pb(onnx_input_path, pb_output_path):
    onnx_model = onnx.load(onnx_input_path)  # load onnx model
    tf_exp = prepare(onnx_model)  # prepare tf representation
    tf_exp.export_graph(pb_output_path)  # export the model

if __name__ == "__main__":
    onnx_input_path = '../onnx/model.onnx'
    pb_output_path = '../tensorflow/model.pb'
 
    onnx2pb(onnx_input_path, pb_output_path)
