Hi Matt,

I double checked that, and found that when I import pvaccess, the behavior in terminal & in jupyter is same.


Oh, OK. I must have misunderstood your earlier reports.
 

 

The pvapy is a Python wrapper of pvaccess (EPICS7 protocol) developed by Sinisa.

It has its own interface for CA client, and does not use libca actually.

But its EPICS7 build does come with a version of libca.

I just happened to find the rare case.

 


My concern is that you were the first to find this problem, but won't be the last.   If "import pvaccess" is loading a CA shared library (and from your report, it sounds like it is), then there is the potential - actually a likliehood - for conflict with pypepics.
