win10 部署serving后，运行examples下的ocr案例没有问题，想运行图像分类案例imagenet报错如下

[meishitouzhele]

File ".\resnet50_web_service.py", line 78 image_service.run_web_service() ^ SyntaxError: invalid syntax 能提供一个运行examples下图像分类的过程吗？，想运行通过后 发布下自己的图像分类model（在centos的docker下能正常的model，想在win10下测试）感谢

1、请问你运行的是原始的resnet50_web_service.py文件么？ 2、检查代码在image_service.run_web_service()前必须有image_service.run_rpc_service() 3、也有可能是缺少flask?

[meishitouzhele]

我是把前必须有image_service.run_rpc_service() 这个注释了，现在放开了，cpu或者gpu报如下we问题

[meishitouzhele]

[meishitouzhele]

运行同目录下的test_image_reader.py有点异常

[meishitouzhele]

额 标记的都不是这个问题吧

[HexToString]

1、test_image_reader.py问题 这个看起来是一个编解码的问题，可能win平台默认的编解码是gbk,指定utf-8即可。 2、倒数第二张图的no attribute 'set gpus'问题 这个看起来像是你使用了gpu,但是ImageService继承自了cpu版本的web_service，如果是使用v0.5.0版本，请使用 if device == "cpu": from paddle_serving_server.web_service import WebService else: from paddle_serving_server_gpu.web_service import WebService 如果还不能解决您的问题，请查一下你引入的继承的WebService，有没有set_gpus方法即可。

另外，请您把您的环境信息最好一并发过来，这样会比较容易定位问题。

至于上面的问题，有点看不太明白，麻烦您详细描述一下是什么情况下报的这个错。

[meishitouzhele]

好的 感谢 我重新整理下。

[HexToString]

您太客气了，用户就是上帝，是我们一贯的服务宗旨。

[HexToString]

仔细看了一下，您的第一个问题貌似是protobuf导致的问题。 您是否修改了相关的内容呢？例如是否修改了proto文件或其相关文件？

[meishitouzhele]

额 没有修改 目前就是win10原生环境 pip安装了 paddlehub，然后能正常使用官网demo和自己训练的model。然后pip安装了paddleserving 运行官方的ocr model能正常发布、调用，然后运行官方的imagenet 发布报错。cpu和gpu都报错

[HexToString]

您使用的是哪个版本的呢？ 麻烦能把pip list打出来看一下么？

[HexToString]

问题的原因是序列化的问题，但是为什么你这会出这个问题，还不能确定。 有一个办法您可以试一下， web_service.py文件中

server_pros = []（将这一句删除） for i, service in enumerate(self.rpc_service_list): p = Process(target=self._launch_rpc_service, args=(i, )) server_pros.append(p)（将这一句删除） for p in server_pros:（将这一句删除） p.start()

[meishitouzhele]

额 我没找到这个文件 web_service.py 请问再哪里？

[HexToString]

这个文章也许可以帮到您，说是win和Linux多进程差异导致的。 https://blog.csdn.net/lijinzemmm/article/details/75735805?utm_medium=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromBaidu%7Edefault-5.control&dist_request_id=1330144.34750.16182099985152017&depth_1-utm_source=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromBaidu%7Edefault-5.control
