How to import Python package into Jython running under Arm Development Studio?

XiaomingZ

Hello,

I was trying to use some APIs in bitstruct package (from: https://pypi.org/project/bitstruct/) in the Jython script file running under Arm Development Studio (ADS) v2021.2 (using "source dump_reg.py" command),  the dump_reg.py is like as below:


import sys, getopt

from arm_ds.debugger_v1 import Debugger
from arm_ds.debugger_v1 import DebugException
from collections import namedtuple
from bitstruct import *
   debugger = Debugger()
   ec = debugger.getExecutionContext(0)
   ec.getExecutionService().stop()
   ec.getExecutionService().waitForStop(0)
   val = ec.getMemoryService().readMemory32(ADDRESS)
   data_reg_name = namedtuple('Data1', ['a', 'b', 'c', 'd'])
    unpacked = unpack('u1u3u4u24', val)
    data1name = RegName(*unpacked)
    print ( data_reg_name )
But got error message:
ERROR(?): ImportError: No module named bitstruct
How can I fix this?
Thanks

    Hi again Xiaoming,

    Apologies for not getting back to you sooner.  I had mistakenly thought that "pip install" would work, but I can now see that it doesn't.

    Jython in Arm DS is v2.7.2.  Is there 2.x-compatible version of bitstruct available?  It appears to be for CPython 3 only.
    If not, then I'm afraid there isn't an easy way to import the package into Arm DS.

    The only workaround I can think of is to copy the relevant bitstruct code into your Jython project.  That seemed to work for me.

    Hope this helps
