Hello,As you can see from the attached screenshot, the warning messages from ca module of pyepics happened when I was doing tasks described as below:
1. I created many epics.PV objects (few hundreds to a thousand); 2. Capture all the readings from these created PV objects in a for loop.It looks like I can use caget_many(<PV list>) to achieve the goals, but the whole logic needs to be well refactored, so what if I want do this in the for-loop way, how can I avoid this UserWarnings, anyone can help me understand this issue?
Thank you, Tong
