I have a Python script called preprocess.py. Write a bash command that runs it on all the files that end with ".checkpoint" in all the subdirectories, subsubdirectories, etc. of the checkpoints/ directory.

You can use the following bash command to run the Python script ` pre process . py ` on all the files that end with ". check point " in all the sub direct ories , sub sub direct ories , etc . of the ` check points /` directory : \n ``` bash \n find check points - type f - name " *. check point " - exec python pre process . py {} \; \n ``` \n This command uses the ` find ` command to search for all files with the name " *. check point " in the ` check points /` directory and its sub direct ories . The `- exec ` option is used to execute the ` pre process . py ` script on each file found . The ` {} ` is a placeholder that represents the file found by the ` find ` command . </s>
