请求频繁或者并发请求出现问题 问题1：程序推理时报错 问题2：内存会一直增大 python版本3.6 paddlepaddle版本1.8.4 推理主要部分 infer_scope = fluid.core.Scope() with fluid.scope_guard(infer_scope): exe = fluid.Executor(place) program, feed_names, fetch_targets = fluid.io.load_inference_model() exe.run(program,feed=inputs,fetch_list=fecth_targets,return_numpy=False)
