我已使用以下格式将.h5文件创建为.pb：
def freeze_session(session, keep_var_names=None, output_names=None, clear_devices=True):
from tensorflow.python.framework.graph_util import convert_variables_to_constants
graph = session.graph
with graph.as_default():
freeze_var_names = list(set(v.op.name for v in tf.global_variables()).difference(keep_var_names or []))
output_names = output_names or []
print(output_names)
#output_names += [v.op.name for v in tf.global_variables()]
print(output_names)
# Graph -> GraphDef ProtoBuf
input_graph_def = graph.as_graph_def()
if clear_devices:
for node in input_graph_def.node:
node.device = ""
#output_graph_def= convert_variables_to_constants(session,input_graph_def,output_node_names.split(","))
frozen_graph = convert_variables_to_constants(session, input_graph_def,
output_names, freeze_var_names)
#print(frozen_graph.input)
#print(output_graph_def)
return frozen_graph
frozen_graph = freeze_session(K.get_session(),
output_names=[out.op.name for out in model.outputs])
tf.train.write_graph(frozen_graph, "/content/drive/My Drive/model", "final_model.pb", as_text=False)
使用SNPE-1.31.0转换.dlc时，出现此错误：
