"""
The ``Task`` class is a code template for a Task object which, together with its connected experiment components,
represents the current running experiment. These connected components include hyperparameters, loggers,
configuration, label enumeration, models, and other artifacts.
The term "main execution Task" refers to the Task context for current running experiment. Python experiment scripts
can create one, and only one, main execution Task. It is traceable, and after a script runs and ClearML stores
the Task in the **ClearML Server** (backend), it is modifiable, reproducible, executable by a worker, and you
can duplicate it for further experimentation.
The ``Task`` class and its methods allow you to create and manage experiments, as well as perform
advanced experimentation functions, such as autoML.
.. warning::
Do not construct Task objects directly. Use one of the methods listed below to create experiments or
reference existing experiments.
Do not define `CLEARML_TASK_*` and `CLEARML_PROC_*` OS environments, they are used internally
for bookkeeping between processes and agents.
For detailed information about creating Task objects, see the following methods:
- Create a new reproducible Task - :meth:`Task.init`
.. important::
In some cases, ``Task.init`` may return a Task object which is already stored in **ClearML Server** (already
initialized), instead of creating a new Task. For a detailed explanation of those cases, see the ``Task.init``
method.
- Manually create a new Task (no auto-logging will apply) - :meth:`Task.create`
- Get the current running Task - :meth:`Task.current_task`
- Get another (different) Task - :meth:`Task.get_task`
.. note::
The **ClearML** documentation often refers to a Task as, "Task (experiment)".
"Task" refers to the class in the ClearML Python Client Package, the object in your Python experiment script,
and the entity with which **ClearML Server** and **ClearML Agent** work.
"Experiment" refers to your deep learning solution, including its connected components, inputs, and outputs,
and is the experiment you can view, analyze, compare, modify, duplicate, and manage using the ClearML
**Web-App** (UI).
Therefore, a "Task" is effectively an "experiment", and "Task (experiment)" encompasses its usage throughout
the ClearML.
The exception to this Task behavior is sub-tasks (non-reproducible Tasks), which do not use the main execution
Task. Creating a sub-task always creates a new Task with a new Task ID.

Creates a new Task (experiment) if:
- The Task never ran before. No Task with the same ``task_name`` and ``project_name`` is stored in
**ClearML Server**.
- The Task has run before (the same ``task_name`` and ``project_name``), and (a) it stored models and / or
artifacts, or (b) its status is Published , or (c) it is Archived.
- A new Task is forced by calling ``Task.init`` with ``reuse_last_task_id=False``.
Otherwise, the already initialized Task object for the same ``task_name`` and ``project_name`` is returned,
or, when being executed remotely on a clearml-agent, the task returned is the existing task from the backend.
.. note::
To reference another Task, instead of initializing the same Task more than once, call
:meth:`Task.get_task`. For example, to "share" the same experiment in more than one script,
call ``Task.get_task``. See the ``Task.get_task`` method for an example.
For example:
The first time the following code runs, it will create a new Task. The status will be Completed.
.. code-block:: py
from clearml import Task
task = Task.init('myProject', 'myTask')
If this code runs again, it will not create a new Task. It does not store a model or artifact,
it is not Published (its status Completed) , it was not Archived, and a new Task is not forced.
If the Task is Published or Archived, and run again, it will create a new Task with a new Task ID.
The following code will create a new Task every time it runs, because it stores an artifact.
.. code-block:: py
task = Task.init('myProject', 'myOtherTask')
d = {'a': '1'}
task.upload_artifact('myArtifact', d)
:param str project_name: The name of the project in which the experiment will be created. If the project does
not exist, it is created. If ``project_name`` is ``None``, the repository name is used. (Optional)
:param str task_name: The name of Task (experiment). If ``task_name`` is ``None``, the Python experiment
script's file name is used. (Optional)
:param TaskTypes task_type: The task type.
Valid task types:
- ``TaskTypes.training`` (default)
- ``TaskTypes.testing``
- ``TaskTypes.inference``
- ``TaskTypes.data_processing``
- ``TaskTypes.application``
- ``TaskTypes.monitor``
- ``TaskTypes.controller``
- ``TaskTypes.optimizer``
- ``TaskTypes.service``
- ``TaskTypes.qc``
- ``TaskTypes.custom``
:param tags: Add a list of tags (str) to the created Task. For example: tags=['512x512', 'yolov3']
:param bool reuse_last_task_id: Force a new Task (experiment) with a previously used Task ID,
and the same project and Task name.
.. note::
If the previously executed Task has artifacts or models, it will not be reused (overwritten)
and a new Task will be created.
When a Task is reused, the previous execution outputs are deleted, including console outputs and logs.
The values are:
- ``True`` - Reuse the last Task ID. (default)
- ``False`` - Force a new Task (experiment).
- A string - You can also specify a Task ID (string) to be reused,
instead of the cached ID based on the project/name combination.
:param bool continue_last_task: Continue the execution of a previously executed Task (experiment)
.. note::
When continuing the executing of a previously executed Task,
all previous artifacts / models/ logs are intact.
New logs will continue iteration/step based on the previous-execution maximum iteration value.
For example:
The last train/loss scalar reported was iteration 100, the next report will be iteration 101.
The values are:
- ``True`` - Continue the last Task ID.
specified explicitly by reuse_last_task_id or implicitly with the same logic as reuse_last_task_id
- ``False`` - Overwrite the execution of previous Task (default).
- A string - You can also specify a Task ID (string) to be continued.
This is equivalent to `continue_last_task=True` and `reuse_last_task_id=a_task_id_string`.
- An integer - Specify initial iteration offset (override the auto automatic last_iteration_offset)
Pass 0, to disable the automatic last_iteration_offset or specify a different initial offset
You can specify a Task ID to be used with `reuse_last_task_id='task_id_here'`
:param str output_uri: The default location for output models and other artifacts.
If True is passed, the default files_server will be used for model storage.
In the default location, ClearML creates a subfolder for the output.
The subfolder structure is the following:
<output destination name> / <project name> / <task name>.<Task ID>
The following are examples of ``output_uri`` values for the supported locations:
- A shared folder: ``/mnt/share/folder``
- S3: ``s3://bucket/folder``
- Google Cloud Storage: ``gs://bucket-name/folder``
- Azure Storage: ``azure://company.blob.core.windows.net/folder/``
- Default file server: True
.. important::
For cloud storage, you must install the **ClearML** package for your cloud storage type,
and then configure your storage credentials. For detailed information, see
`ClearML Python Client Extras <./references/clearml_extras_storage/>`_ in the "ClearML Python Client
Reference" section.
:param auto_connect_arg_parser: Automatically connect an argparse object to the Task. Supported argument
parsers packages are: argparse, click, python-fire, jsonargparse.
The values are:
- ``True`` - Automatically connect. (default)
- ``False`` - Do not automatically connect.
- A dictionary - In addition to a boolean, you can use a dictionary for fined grained control of connected
arguments. The dictionary keys are argparse variable names and the values are booleans.
The ``False`` value excludes the specified argument from the Task's parameter section.
Keys missing from the dictionary default to ``True``, you can change it to be ``False`` by adding
``*`` key as ``False`` to the dictionary.
An empty dictionary defaults to ``False``.
For example:
.. code-block:: py
auto_connect_arg_parser={'do_not_include_me': False, }
.. code-block:: py
auto_connect_arg_parser={"only_include_me": True, "*": False}
.. note::
To manually connect an argparse, use :meth:`Task.connect`.
:param auto_connect_frameworks: Automatically connect frameworks This includes patching MatplotLib, XGBoost,
scikit-learn, Keras callbacks, and TensorBoard/X to serialize plots, graphs, and the model location to
the **ClearML Server** (backend), in addition to original output destination.
The values are:
- ``True`` - Automatically connect (default)
- ``False`` - Do not automatically connect
- A dictionary - In addition to a boolean, you can use a dictionary for fined grained control of connected
frameworks. The dictionary keys are frameworks and the values are booleans, other dictionaries used for
finer control or wildcard strings.
In case of wildcard strings, the local path of a model file has to match at least one wildcard to be
saved/loaded by ClearML. Example:
{'pytorch' : '*.pt', 'tensorflow': ['*.h5', '*']}
Keys missing from the dictionary default to ``True``, and an empty dictionary defaults to ``False``.
Supported keys for finer control:
{'tensorboard': {'report_hparams': bool}} # whether to report TensorBoard hyperparameters
For example:
.. code-block:: py
auto_connect_frameworks={
'matplotlib': True, 'tensorflow': ['*.hdf5, 'something_else*], 'tensorboard': True,
'pytorch': ['*.pt'], 'xgboost': True, 'scikit': True, 'fastai': True,
'lightgbm': True, 'hydra': True, 'detect_repository': True, 'tfdefines': True,
'joblib': True, 'megengine': True, 'catboost': True
}
.. code-block:: py
auto_connect_frameworks={'tensorboard': {'report_hparams': False}}
:param bool auto_resource_monitoring: Automatically create machine resource monitoring plots
These plots appear in the **ClearML Web-App (UI)**, **RESULTS** tab, **SCALARS** sub-tab,
with a title of **:resource monitor:**.
The values are:
- ``True`` - Automatically create resource monitoring plots. (default)
- ``False`` - Do not automatically create.
- Class Type - Create ResourceMonitor object of the specified class type.
:param auto_connect_streams: Control the automatic logging of stdout and stderr
The values are:
- ``True`` - Automatically connect (default)
- ``False`` - Do not automatically connect
- A dictionary - In addition to a boolean, you can use a dictionary for fined grained control of stdout and
stderr. The dictionary keys are 'stdout' , 'stderr' and 'logging', the values are booleans.
Keys missing from the dictionary default to ``False``, and an empty dictionary defaults to ``False``.
Notice, the default behaviour is logging stdout/stderr the
`logging` module is logged as a by product of the stderr logging
For example:
.. code-block:: py
auto_connect_streams={'stdout': True, 'stderr': True, 'logging': False}
:param deferred_init: (default: False) Wait for Task to be fully initialized (regular behaviour).
** BETA feature! use with care **
If set to True, `Task.init` function returns immediately and all initialization / communication
to the clearml-server is running in a background thread. The returned object is
a full proxy to the regular Task object, hence everything will be working as expected.
Default behaviour can be controlled with:
`CLEARML_DEFERRED_TASK_INIT=1`
Notes:
- Any access to the returned proxy `Task` object will essentially wait for the `Task.init`
to be completed. For example: `print(task.name)` will wait for `Task.init` to complete in the
background and then return the `name` property of the task original object
- Before `Task.init` completes in the background, auto-magic logging
(console/metric) might be missed
- If running via an agent, this argument is ignored,
and Task init is called synchronously (default)

:param task_name: Set the name of the remote task. Required if base_task_id is None.
:param task_type: Optional, The task type to be created. Supported values: 'training', 'testing', 'inference',
'data_processing', 'application', 'monitor', 'controller', 'optimizer', 'service', 'qc', 'custom'
:param repo: Remote URL for the repository to use, or path to local copy of the git repository
Example: 'https://github.com/allegroai/clearml.git' or '~/project/repo'
:param branch: Select specific repository branch/tag (implies the latest commit from the branch)
:param commit: Select specific commit id to use (default: latest commit,
or when used with local repository matching the local commit id)
:param script: Specify the entry point script for the remote execution. When used in tandem with
remote git repository the script should be a relative path inside the repository,
for example: './source/train.py' . When used with local repository path it supports a
direct path to a file inside the local repository itself, for example: '~/project/source/train.py'
:param working_directory: Working directory to launch the script from. Default: repository root folder.
Relative to repo root or local folder.
:param packages: Manually specify a list of required packages. Example: ["tqdm>=2.1", "scikit-learn"]
or `True` to automatically create requirements
based on locally installed packages (repository must be local).
:param requirements_file: Specify requirements.txt file to install when setting the session.
If not provided, the requirements.txt from the repository will be used.
:param docker: Select the docker image to be executed in by the remote session
:param docker_args: Add docker arguments, pass a single string
:param docker_bash_setup_script: Add bash script to be executed
inside the docker before setting up the Task's environment
:param argparse_args: Arguments to pass to the remote execution, list of string pairs (argument, value)
Notice, only supported if the codebase itself uses argparse.ArgumentParser
:param base_task_id: Use a pre-existing task in the system, instead of a local repo/script.
Essentially clones an existing task and overrides arguments/requirements.
:param add_task_init_call: If True, a 'Task.init()' call is added to the script entry point in remote execution.
