我用这样的pip 安装了Dask:

pip install dask

当我尝试做时,import dask.dataframe as dd我收到以下错误消息:

>>> import dask.dataframe as dd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/path/to/venv/lib/python2.7/site-packages/dask/__init__.py", line 5, in <module>
    from .async import get_sync as get
  File "/path/to/venv/lib/python2.7/site-packages/dask/async.py", line 120, in <module>
    from toolz import identity
ImportError: No module named toolz
No module named toolz

我注意到文档说明了

pip install dask:仅安装dask,它仅依赖于标准库.如果您只需要任务计划程序,这是合适的.

所以我很困惑为什么这不起作用.
