Different behavior for same python version on different linux VMs

Python Help

This is from Linux VM #1

=->python3Python 3.12.12 (main, Jan  6 2026, 09:23:36) [GCC 8.5.0 20210514 (Red Hat 8.5.0-28.0.1)] on linuxType “help”, “copyright”, “credits” or “license” for more information.

from pybrm import Client
c = Client()
f = c.flist()
f.PIN_FLD_POID = (“/account”, 100, 0)
f
{}

Note how f doesn’t print anything though PIN_FLD_POID is assigned to it.

Now this is VM #2 with the same python version

=->python3Python 3.12.12 (main, Jan  6 2026, 09:23:36) [GCC 8.5.0 20210514 (Red Hat 8.5.0-28.0.1)] on linuxType “help”, “copyright”, “credits” or “license” for more information.

from pybrm import Client
c = Client()
f = c.flist()
f.PIN_FLD_POID = (“/account”, 100, 0)
f
{‘PIN_FLD_POID’: Poid(type=‘/account’, id=100, revision=0, database=1)}

Notice how f prints whatever was assigned to it.

Why this difference in behavior in different VMs though python versions are exactly the same.

Thanks in advance.

Are the pybrm versions the same? Run this code and tell us the output:

import pybrm
import sys
print("python:", sys.version)
print("pybrm file:", pybrm.__file__)
print("pybrm version:", getattr(pybrm, "__version__", "NO __version__"))

Also give us the output of this code:

import pkgutil, pybrm
mods = [m.name for m in pkgutil.iter_modules(pybrm.__path__)]
print("pybrm submodules:", mods)

It’s a C extension. On the second VM did you forget to set PIN_HOME ?

Which CPU architectures do the VMs have (e.g. ARM or x86)?

pybrm was recently upgraded on VM #2 (earlier, behavior was the same on both VMs) which I wasn’t aware of. Thank you.
