How to add comments inside tensorflow object detection API's pipeline configuration file (typically named pipeline.conf)?
The corresponding official documentation does not mention any way to do so.
Simply use # comment here wherever you want.
Keep in mind that the pipeline.config is written into the model_dir. Therefore, if it is the same directory as your pipeline.config, it will be overridden, and the comments will be deleted. You can simply avoid this by naming the pipeline.config file you use differently.
