# Logging

🤗 Diffusers has a centralized logging system to easily manage the verbosity of the library. The default verbosity is set to `WARNING`.

To change the verbosity level, use one of the direct setters. For instance, to change the verbosity to the `INFO` level.

```python
import diffusers

diffusers.logging.set_verbosity_info()
```

You can also use the environment variable `DIFFUSERS_VERBOSITY` to override the default verbosity. You can set it
to one of the following: `debug`, `info`, `warning`, `error`, `critical`. For example:

```bash
DIFFUSERS_VERBOSITY=error ./myprogram.py
```

Additionally, some `warnings` can be disabled by setting the environment variable
`DIFFUSERS_NO_ADVISORY_WARNINGS` to a true value, like `1`. This disables any warning logged by
[`logger.warning_advice`]. For example:

```bash
DIFFUSERS_NO_ADVISORY_WARNINGS=1 ./myprogram.py
```

Here is an example of how to use the same logger as the library in your own module or script:

```python
from diffusers.utils import logging

logging.set_verbosity_info()
logger = logging.get_logger("diffusers")
logger.info("INFO")
logger.warning("WARN")
```


All methods of the logging module are documented below. The main methods are
[`logging.get_verbosity`] to get the current level of verbosity in the logger and
[`logging.set_verbosity`] to set the verbosity to the level of your choice. 

In order from the least verbose to the most verbose:

|                                                    Method | Integer value |                                         Description |
|----------------------------------------------------------:|--------------:|----------------------------------------------------:|
| `diffusers.logging.CRITICAL` or `diffusers.logging.FATAL` |            50 |                only report the most critical errors |
|                                 `diffusers.logging.ERROR` |            40 |                                  only report errors |
|   `diffusers.logging.WARNING` or `diffusers.logging.WARN` |            30 |           only report errors and warnings (default) |
|                                  `diffusers.logging.INFO` |            20 | only report errors, warnings, and basic information |
|                                 `diffusers.logging.DEBUG` |            10 |                              report all information |

By default, `tqdm` progress bars are displayed during model download. [`logging.disable_progress_bar`] and [`logging.enable_progress_bar`] are used to enable or disable this behavior.
