Subject: PyEPICS timeout in jupyter

Hi,

I am using PyEPICS 3.3.1 together with my conda3 + Python 3.6.

In my terminal, I have no problem to do for example epics.caget().

However, I always get a time out problem in my jupyter notebook when using PyEPICS.

The error message is like:

anaconda3/lib/python3.6/site-packages/epics/ca.py:1306: UserWarning: ca.get('test') timed out after 5.00 seconds.

  warnings.warn(msg % (name(chid), timeout))

 

Is there any environment variable I should set?

 

With cothread, I do not have the same issue, therefore, it does not sound like a general EPICS CA variable problem.

 

Thanks,

Guobao
