title: Storing Task Data Offline
---

If your computer is offline, or you do not want a Task's data and logs stored in the ClearML Server, use
the **Offline Mode** option. In this mode, all the data and logs that the Task captures from the code are stored in a 
local folder, which can be later uploaded to the [ClearML Server](../deploying_clearml/clearml_server.md).

## Setting Task to offline mode

Before initializing a Task, use the [Task.set_offline](../references/sdk/task.md#taskset_offline) class method and set the 
`offline_mode` argument to `True`.

```python
from clearml import Task
# Use the set_offline class method before initializing a Task
Task.set_offline(offline_mode=True)
# Initialize a Task 
task = Task.init(project_name="examples", task_name="my_task")

# Rest of code is executed. All data is logged locally and not onto the server
```

The method returns the Task ID and a path to the local session folder:

```console
ClearML Task: created new task id=offline-372657bb04444c25a31bc6af86552cc9
...
...
ClearML Task: Offline session stored in /home/user/.clearml/cache/offline/b786845decb14eecadf2be24affc7418.zip
```

All the information captured by the Task is saved locally. Once the task script finishes execution, it's zipped. The 
session's zip folder's location is `~/.clearml/cache/offline/<task_id>.zip`.

## Uploading local session

In order to upload to the ClearML Server the local execution data that the Task captured offline, use the 
[Task.import_offline_session](../references/sdk/task.md#taskimport_offline_session) method. This method will upload the 
Task's full execution details and outputs. 

```python
from clearml import Task

Task.import_offline_session(session_folder_zip="path/to/session/.clearml/cache/offline/b786845decb14eecadf2be24affc7418.zip")
```

In the `session_folder_zip` argument, insert the path to the zip folder containing the session.

This method returns a link to the Task's results page on the ClearML Server:

```console
ClearML: Importing offline session from /home/user/.clearml/cache/offline/b786845decb14eecadf2be24affc7418.zip
ClearML results page: https://app.community.clear.ml/projects/4043a1657f374e9298649c6ba72ad233/experiments/bb8b0f6fa0f94536a0d27fb55f02d3a5/output/log
```

The session details can be viewed in the ClearML WebApp, in the "my_task" experiment of the "examples" 
project, as specified when initializing the Task.
