我们有多个模型，需要做通用inference，需要载入多个模型 如果只load任意一个模型都是ok的 但如果load一个模型后，load另一个模型，如果其中一个模型用到lod_tensor，就会报错。 函数代码如下： place = fluid.CPUPlace() exe = fluid.Executor(place) [inference_program, _, fetch_targets] = ( fluid.io.load_inference_model(dirname=model_path[0], executor=exe, model_filename=model_path[1], params_filename=params_path[1]))

错误如下： Error Occurs, info:enforce version == 0U failed, 1015534361 != 0 Only version 0 is supported at [/paddle/paddle/fluid/framework/lod_tensor.cc:276] PaddlePaddle Call Stacks: 0 0x7f3e15df5376p
