Question

我刚尝试分发pip install。 dask-scheduler正在运行但结果返回为错误。这是安装问题吗？会不会丢失任何包裹？或者这是版本冲突问题吗？

>>> from distributed import Client
>>> c=Client()
>>> def sq(x):
...     return x+1
...
>>> c.submit(sq,2)
>>> x=c.submit(sq,2)
>>> x
<Future: status: finished, type: int, key: sq-dcc8bc750c0ce57c2d052675a6cd33b9>

>>> x.result()

dask分布式结果为TypeError
