Python Dask distributed.core-错误-'；元组'；对象不支持项分配

我在我的项目中使用Dask和cython，在向客户机注册后调用cython代码，并将从cython代码获得的结果收集到我的Dask python代码中。当我创建一个processs=True的集群时，它可以正常工作。但是，一旦我写入processs=False，它就会给出以下错误：

 distributed.core - ERROR - 'tuple' object does not support item assignment
Traceback (most recent call last):
  File "/home/user/anaconda3/envs/Dask/lib/python3.7/site-packages/distributed/core.py", line 555, in handle_stream

    buffers[i] = buf.cast(mv.format)
TypeError: 'tuple' object does not support item assignment
distributed.worker - ERROR - 'tuple' object does not support item assignment

我正在使用以下代码段：

from dask.distributed import Client, LocalCluster,wait
cluster=LocalCluster(processes=False)
client=Client(cluster)
client.register_worker_callbacks(init_pyx)  ## init_pyx is a function by which worker register to cython code
df = dd.read_csv(path_to_csv_file)
processed_df=df.map_partitions(lambda part: handle_partition(part),meta=meta)  #handle partition is function which uses cython code to preprocess each partition of dataframe, meta is metadata related to preproceesed part
client.close() 

另外，早些时候我遇到了与内存视图相关的问题，但是当我重新安装dask时，内存视图错误消失了。现在出现了一个与“TypeError:“tuple”对象不支持项分配”相关的新错误

我也是达斯克的新手，如果有人知道如何解决这个问题，请在这方面帮助我。

提前感谢。

请分享您的代码，这是一个最小的可复制示例。例如，您是否有一个形状或步幅包含零的memoryview？亲爱的mdurant，当我重新安装dask时，问题已经解决。谢谢你的友好回复。但是，请再次查看帖子，其中说明了一个奇怪的问题。您是如何安装dask的，以及您拥有的dask和分发版的确切版本？我正在使用conda安装dask。我使用的是与（2021.3.1）相同版本的dask和分布式dask。
