 ### Creating Config File
 
-Write all tensor names corresponding to the Matmul operators that need to be updated into a text file, with each tensor name occupying one line. Build a model to load the configuration file, set the configuration file, and the content of the configuration file `config.ini` is as follows:

 ```text
