我正在尝试通过以下代码保存Keras / Tensorflow模型:
qpdf --empty --pages file1.pdf file2.pdf -- merged.pdf
我从Jupyter Notebook中收到以下错误消息:
def export_model(saver, model, input_node_names, output_node_name):
MODEL_NAME = 'lyme_model'
tf.train.write_graph(K.get_session().graph_def, 'out', \
MODEL_NAME + '_graph.pbtxt')
saver.save(K.get_session(), 'out/' + MODEL_NAME + '.chkp')
input_graph_path = 'out/'+MODEL_NAME+'.pbtxt'
checkpoint_path = 'out/'+MODEL_NAME+'.chkp'
input_saver_def_path = ""
input_binary = False
restore_op_name = "save/restore_all"
filename_tensor_name = "save/Const:0"
output_frozen_graph_name = 'out/frozen_'+MODEL_NAME+'.pb'
clear_devices = True
freeze_graph.freeze_graph(input_graph_path, input_saver_def_path,
input_binary, checkpoint_path, output_node_name,
restore_op_name, filename_tensor_name,
output_frozen_graph_name, clear_devices, "")
input_graph_def = tf.GraphDef()
with tf.gfile.Open('out/frozen_' + MODEL_NAME + '.pb', "rb") as f:
input_graph_def.ParseFromString(f.read())
output_graph_def = optimize_for_inference_lib.optimize_for_inference(
input_graph_def, input_node_names, [output_node_name],
tf.float32.as_datatype_enum)
with tf.gfile.FastGFile('out/opt_' + MODEL_NAME + '.pb', "wb") as f:
f.write(output_graph_def.SerializeToString())
print("graph saved!")
export_model(tf.train.Saver(), model, ["input_1"], "prediction")
是什么引起了这个问题?我什至没有在任何地方看到列表操作,所以我想它们发生在Keras / Tensorflow后端的某个地方。想知道如何解决这个问题。谢谢!
P.S。 export_model()方法取自here。
