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

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...

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
