【创建tensorflow severing容器出错】failed: Out of range: Read less bytes than requested【已解决】
〇、前言
最近在做tensorflow severing模型部署，拿了个yolov5训练出来的pt模型做实验。前几天一切正常，就在今天创建tensorflow severing容器的时候遇到了错误，环境、命令、模型、配置文件这些都没有变动，突然就出现了这个错误，发现网上遇到类似情况的极其稀少，找了很久在https://github.com/tensorflow/tensorflow/issues/21544中才找到了问题所在，并完美解决问题。如果遇到同样问题的同学看到了这篇文章，希望能帮到你！
一、问题描述
创建tensorflow severing容器的时候遇到了错误，环境、命令、模型、配置文件这些都没有变动，突然就出现了这个错误。
1. 错误摘要(f方便被搜索到)：
E tensorflow_serving/util/retrier.cc:37] Loading servable: {name: yolov5_saved_model version: 1} failed: Out of range: Read less bytes than requestedFailed to start server. Error: Unknown: 1 servable(s) did not become available: {{{name: yolov5_saved_model version: 1} due to error: Out of range: Read less bytes than requested}, }2022-07-30 11:15:09.097717: I tensorflow_serving/core/basic_manager.cc:279] Unload all remaining servables in the manager.
2. 错误截图：
3. 完整错误代码如下：
（见附录）
二、问题分析：
错误是由文件损坏导致，具体怎么损坏，我想到两种可能：上传文件中断或出错、完好的文件由于磁盘问题导致损坏。
我的是第二种
参考了https://github.com/tensorflow/tensorflow/issues/21544才发现的。
三、解决方法：
删除模型及配置文件，重新上传。
如果没有提前没有备份，或者不知道文件是否损坏，则可以重新进行模型转换生成saved model模型，并新建配置文件。
下图是我重新上传的文件结构和文件截图。
