在TensorFlow中加载和运行ONNX模型需要使用TensorFlow的ONNX模型转换工具。具体步骤如下:
pip install tensorflow-onnx
import onnx
from onnx_tf.backend import prepare
onnx_model = onnx.load("model.onnx")
tf_rep = prepare(onnx_model)
tf_rep.export_graph("model.pb")
import tensorflow as tf
with tf.io.gfile.GFile("model.pb", "rb") as f:
graph_def = tf.compat.v1.GraphDef()
graph_def.ParseFromString(f.read())
with tf.Graph().as_default() as graph:
tf.import_graph_def(graph_def, name="")
sess = tf.compat.v1.Session(graph=graph)
input_tensor = graph.get_tensor_by_name("input:0")
output_tensor = graph.get_tensor_by_name("output:0")
# 输入数据
input_data = ... # 输入数据
output_data = sess.run(output_tensor, feed_dict={input_tensor: input_data})
通过以上步骤,就可以在TensorFlow中加载和运行ONNX模型了。
