[Python知识库]【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 requested
• Failed 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。

models
|----model1
|---- ----1
|---- ---- ----assets
|---- ---- ---- ----variables
|---- ---- ---- ----variables.data-00000-of-00001
|---- ---- ----variables.index
|---- ---- ----saved_model.pb
|----model.config
