Hi,
I am just facing the same question with that email "a simple question about pyepics".
OS is redhat6, python is 2.7.6
Here is what I tried:
1, [root@localhost linux64]# echo $PYEPICS_LIBCA
/test/base/lib/linux-x86_64/libca.so
2, [root@localhost linux64]# echo $EPICS_BASE
/test/base
3, [root@localhost linux64]# echo $EPICS_HOST_ARCH
linux-x86_64
4, in python I am typing
Python 2.7.6 (default, Aug 28 2018, 07:42:21)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from epics import caget
>>> m1 = caget('root:ai2')
cannot connect to root:ai2
5, PV named 'root:ai2' does exist
iocRun: All initialization complete
## Start any sequence programs
#seq sncExample, "user=root"
epics> dbl
root:xxxExample
root:calcExample
root:calcExample1
root:calc1
root:calcExample2
root:calc2
root:calcExample3
root:calc3
root:subExample
root:aSubExample
root:compressExample
root:aiExample
root:aiExample1
root:ai1
root:aiExample2
root:ai2
root:aiExample3
root:ai3
What can I do then?
