# 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.
