# Known Issues

## CatBoostError: Can't create train working dir: catboost\_info error

CatBoost create a directory for persisting his state. But the Run does not allow you to create file anywhere.

### Change the train directory to: `/tmp`

*If the state doesn't need to be persisted*, the `/tmp` directory is the way to go.

```python
model.set_params(train_dir='/tmp/catboost_info')
```

### Change the train directory to: `model_directory`

If the state does need to be persisted, store everything inside the `model_directory` as this folder will be reused for the Out-of-Sample phase.

```python
info_path = os.path.join(model_directory, 'catboost_info')
model.set_params(train_dir=info_path)
```
