# How to Get the Complete Config
We also provide the `print_config.py` tools to print the complete configuration of the given experiment.
You can check each item of the config before the training by using the following command.
## Description
`tools/misc/print_config.py` prints the whole config verbatim, expanding all its imports.
```shell
python tools/misc/print_config.py ${CONFIG} [--cfg-options ${CFG_OPTIONS}]
```
Description of all arguments:
- `config` : The path of the model config file.
- `--cfg-options`: If specified, the key-value pair config will be merged into the config file, for more details please refer to [Learn about Configs](../user_guides/config.md)
## Examples
```shell
# Print a complete config
python tools/misc/print_config.py configs/t2t_vit/t2t-vit-t-14_8xb64_in1k.py
# Save the complete config to a independent config file.
python tools/misc/print_config.py configs/t2t_vit/t2t-vit-t-14_8xb64_in1k.py > final_config.py
```
