Recently, I was doing tensorflow severing model deployment, and I took a yolov5 trained pt model for experiment. Everything was fine for the first few days, but today I encountered an error when creating the tensorflow severing container, the environment, commands, models, configuration files have not changed, and suddenly this error appeared.

1. Problem description

There was an error when creating the tensorflow searching container. The environment, commands, models, and configuration files did not change. Suddenly, this error occurred.

1. Error summary (F is easy to search):

• 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.

3. The complete error code is as follows:

(see Appendix)

2. Problem analysis:

The error is caused by the damage of the file. Specifically, I think of two possibilities: the interruption or error of the uploaded file, and the damage of the intact file due to disk problems.

Mine is the second kind

Reference https://github.com/tensorflow/tensorflow/issues/21544 Just found out. 👇

3. Solution:

Delete the model and configuration file and upload it again.

If there is no backup in advance, or you don’t know whether the file is damaged, you can re convert the model to generate a saved model model and create a new configuration file.

The following figure is the file structure and screenshot of the file I uploaded again.
