To run two tasks in parallel in Flyte, you can define them within a workflow without specifying dependencies between them. This will allow Flyte to execute them concurrently. Here's an example:
Copy code
from flytekit import task, workflow

@task
def task_a() -> str:
    return "Task A completed"

@task
def task_b() -> str:
    return "Task B completed"

@workflow
def my_workflow() -> (str, str):
    result_a = task_a()
    result_b = task_b()
    return result_a, result_b

if __name__ == "__main__":
    print(my_workflow())
In this example,
task_a
and
task_b
will run in parallel because there are no dependencies specified between them. Would you like more detail? Sources: - Discuss Flyte 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@RunLLM can we call a task from within a task
r
No, calling a task from within another task directly is not supported in Flyte. Instead, you should use dynamic workflows to achieve similar functionality. Would you like more detail?

@RunLLM i want 2 parallel flows where first 3 tasks are related and next 3 tasks are related but these 2 flows are separate and should run in parallel
@RunLLM i want 2 parallel flows where first 3 tasks are related and next 3 tasks are related but these 2 flows are separate and should run in parallel
r
To achieve two parallel flows where each flow consists of three related tasks, you can define two separate workflows for each flow and then call these workflows in a main workflow to run them in parallel. Here's an example:
Copy code
from flytekit import task, workflow

@task
def task1() -> str:
    return "Task 1 completed"

@task
def task2() -> str:
    return "Task 2 completed"

@task
def task3() -> str:
    return "Task 3 completed"

@task
def task4() -> str:
    return "Task 4 completed"

@task
def task5() -> str:
    return "Task 5 completed"

@task
def task6() -> str:
    return "Task 6 completed"

@workflow
def flow1() -> (str, str, str):
    result1 = task1()
    result2 = task2()
    result3 = task3()
    return result1, result2, result3

@workflow
def flow2() -> (str, str, str):
    result4 = task4()
    result5 = task5()
    result6 = task6()
    return result4, result5, result6

@workflow
def main_workflow() -> ((str, str, str), (str, str, str)):
    flow1_results = flow1()
    flow2_results = flow2()
    return flow1_results, flow2_results

if __name__ == "__main__":
    print(main_workflow())
In this example: 1.
flow1
consists of
task1
,
task2
, and
task3
. 2.
flow2
consists of
task4
,
task5
, and
task6
. 3. The
main_workflow
calls
flow1
and
flow2
to run them in parallel. Would you like more detail? Sources: - Flyte Workflows 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@RunLLM how to fetch all executions of a workflow
r
To fetch all executions of a workflow in Flyte, you can use the
list_executions_paginated
method from the FlyteRemote client. Here's an example:
Copy code
from flytekit.remote import FlyteRemote
from flytekit.configuration import Config
from flytekit.models.common import NamedEntityIdentifier

# Initialize FlyteRemote
remote = FlyteRemote(config=Config.auto(), default_project="your_project", default_domain="your_domain")

# Define the workflow identifier
workflow_identifier = NamedEntityIdentifier(project="your_project", domain="your_domain", name="your_workflow_name")

# Fetch all executions of the workflow
executions, _ = remote.client.list_executions_paginated(limit=100, identifier=workflow_identifier)

# Print execution IDs
for execution in executions:
    print(execution.id)
In this example: 1. Replace
"your_project"
,
"your_domain"
, and
"your_workflow_name"
with your actual project, domain, and workflow name. 2. The
list_executions_paginated
method fetches executions with a specified limit. You can adjust the limit as needed. Would you like more detail? Sources: - Discuss Flyte 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

how to check the value of Taskresult.failed and put a if clause i am getting an error to use bitwise
@RunLLM ow to check the value of Taskresult.failed and put a if clause i am getting an error to use bitwise
r
In Flyte, you can use the
conditional
construct to check the value of a task result and apply conditional logic. Flyte requires the use of bitwise operators (
&
,
|
) instead of logical operators (
and
,
or
) due to Python's PEP-335. Here's an example of how to check if a task result indicates failure and apply conditional logic:
Copy code
from flytekit import task, workflow, conditional

@task
def task_that_may_fail() -> bool:
    # Simulate a task that may fail
    import random
    return random.choice([True, False])  # True indicates success, False indicates failure

@task
def handle_failure() -> str:
    return "Task failed"

@task
def handle_success() -> str:
    return "Task succeeded"

@workflow
def main_workflow() -> str:
    result = task_that_may_fail()
    return (
        conditional("check_task_result")
        .if_(result.is_false())
        .then(handle_failure())
        .else_()
        .then(handle_success())
    )

if __name__ == "__main__":
    print(main_workflow())
In this example: 1.
task_that_may_fail
simulates a task that may fail by returning a boolean value. 2.
handle_failure
and
handle_success
are tasks that handle the failure and success cases, respectively. 3. The
main_workflow
uses the
conditional
construct to check if the result of
task_that_may_fail
is
False
(indicating failure) and then calls the appropriate task. Would you like more detail? Sources: - Flyte Conditionals 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@RunLLM specifically want to know about the TaskResult class failed parameter
r
I'm not able to find any data sources to answer your question. Could you provide more details or context about where and how you are encountering the
TaskResult
class and its
failed
parameter? If this doesn't help, please reach out to the Flyte support team for further assistance. 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.
