关于dask和x27的进度报告；s集u指数

我试图在整个脚本周围包装一个进度指示器。但是，

set_index（…，compute=False）

仍然在调度程序上运行任务，可以在web界面中看到

如何报告

set\u index

步骤的进度

import dask.dataframe as dd
from dask.distributed import Client, progress

if __name__ == '__main__':

  with Client() as client:

    df = dd.read_csv('big.csv')

    # I can see on the web interface that something is happening.
    # This blocks 20-30s on this particular CSV.
    df = df.set_index('id', compute=False)

    # Progress reporting works from here
    out = client.compute(
      df
    )
    progress(out)

    # out.result()
    # ...
