错误描述

paddle3.0无法导出2.x一样的静态模型，导致无法推理，如何解决

稳定复现步骤 & 代码

导出代码：
# Convert to static graph with specific input description
model = paddle.jit.to_static(model, input_spec=input_spec)
# Save in static graph model.
save_path = os.path.join(path, file_prefix)
logger.info("Exporting inference model to %s" % save_path)
paddle.jit.save(model, save_path)
logger.info("Inference model exported.")
