Root Cause

The pipeline API was called with a task identifier that does not match any registered pipeline task, often due to typos or using a non-standard task name.

generic

中文

pipeline API 被调用时使用了未注册的任务标识符，通常是由于拼写错误或使用了非标准任务名称。

Workarounds

  1. 95% success Correct the task name to a valid one: `from transformers import pipeline; pipe = pipeline('summarization', model='facebook/bart-large-cnn')` 
    Correct the task name to a valid one: `from transformers import pipeline; pipe = pipeline('summarization', model='facebook/bart-large-cnn')`
  2. 90% success Use the model's default task by omitting the task argument: `pipe = pipeline(model='facebook/bart-large-cnn')` which auto-detects the task. 
    Use the model's default task by omitting the task argument: `pipe = pipeline(model='facebook/bart-large-cnn')` which auto-detects the task.
  3. 70% success If the task is truly custom, register it with `from transformers.pipelines import SUPPORTED_TASKS; SUPPORTED_TASKS['custom_task'] = {...}` 
    If the task is truly custom, register it with `from transformers.pipelines import SUPPORTED_TASKS; SUPPORTED_TASKS['custom_task'] = {...}`

  2. Use the model's default task by omitting the task argument: `pipe = pipeline(model='facebook/bart-large-cnn')` which auto-detects the task.
  3. If the task is truly custom, register it with `from transformers.pipelines import SUPPORTED_TASKS; SUPPORTED_TASKS['custom_task'] = {...}`

Dead Ends

Common approaches that don't work:

  1. Installing an older version of transformers (e.g., 4.20.0) to bypass the error 80% fail

    Older versions have even fewer supported tasks; the invalid task will still fail.

  2. Creating a custom pipeline with the same name without registering it 90% fail

    The pipeline registry is static; custom tasks must be registered via `PipelineRegistry` or by using a valid alias.

  3. Changing the model name in the pipeline call 95% fail

    The error is about the task argument, not the model; changing the model does not affect task validation.
