Hey,
as I wrote in my firsts mail: I'm running Debian stretch (64 bit). The
version of python3 from the apt-repositories is 3.5
~ > uname -a
Linux lenovoT450s 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u2
(2019-05-13) x86_64 GNU/Linux
~ > python3 -c "import sys; print(sys.version_info)"
sys.version_info(major=3, minor=5, micro=3, releaselevel='final',
serial=0)
If the requirement is python3.6, it is clear why it is not working on my
system.
But p4p works for me!
Cheers,
Florian

Okay, you either have 32-bit machine or python version lower than 3.6.
If you send me the output of the following two commands, I will build
the packages for your platform:
uname -a
python -c "import sys; print(sys.version_info)"
Thanks,
Sinisa

Hello,
The "pvaccess" python module is part of pvapy, which you should be able
to get via conda or pip.
What was the problem with your pvapy pip install?
Thanks,
Sinisa

Hey Kay and David,
during the EPICS7 training at the collaboration meeting, we were using
a PVA client written in python.
This client imports the module "pvaccess".
For a small project I wanted to write my own PVA client in python, but
I cannot find this library.
Using `pip search pvaccess` I found a module called p4p (maintained by
David?) instead.
Googeling I found also pvapy which I could not install via pip.
Are there any recommendations which module to use?
In case it matters: My environment is Debian Stretch with Base 7.0.2.2.
Best regards,
Florian
