我写了一个程序，它通过matplotlib获取数据并绘制它。它在一台计算机上没有问题但在另一台计算机上我得到错误：
TypeError: Couldn't find foreign struct converter for 'cairo.Context'
Traceback (most recent call last):
File "/usr/lib/python3.5/idlelib/run.py", line 125, in main
seq, request = rpc.request_queue.get(block=True, timeout=0.05)
File "/usr/lib/python3.5/queue.py", line 172, in get raise Empty queue.Empty
我该怎么做才能获得cairo.Context转换器？
