我已经分发了dask，这是对工作流程（完美）的更大努力的一部分，并且在我的dask工作者中看到了一个错误。工人收到了工作，但很快提出了例外情况：
TypeError: can not serialize 'Variable' object
完整跟踪为：

我已经将其归结为一个非常小的测试用例，我认为这是相当有代表性的。它引起了同样的问题：
from distributed.protocol.core import dumps_msgpack
from distributed.variable import Variable
from distributed.client import Client
client = Client(address='10.72.112.29:38786')
var = Variable(name='test', client=client)
msg = {'op': 'variable_get', 'timeout': 0, 'name': var, 'client': client.id, 'reply': True}
d = dumps_msgpack(msg)
此示例会产生错误消息，但也会显示一些版本不匹配（我不认为是问题所在）：

我缺少包裹吗？我可以提供安装脚本等，但是涉及到一些脚本-客户端是本地python env，调度程序和工作程序是docker。
