Re: passing multiple string to a command line option
Seems like self.ptype is a type that has __init__ with no arguments (other than self). You can add print type(self.ptype) as first line of convert to see what type it is (or place a breakpoint there). -- http://mail.python.org/mailman/listinfo/python-list
Re: passing multiple string to a command line option
That print command generated a lot of errors. Since that error in my first post is related to the python code in simulator, I emailed them and consulted for help. Seems that it is going to be fixed Thanks for your kindness :) // Naderan *Mahmood; - Original Message - From: Miki Tebeka miki.teb...@gmail.com To: comp.lang.pyt...@googlegroups.com Cc: python mailing list python-list@python.org; Miki Tebeka miki.teb...@gmail.com; Mahmood Naderan nt_mahm...@yahoo.com Sent: Friday, October 7, 2011 5:41 PM Subject: Re: passing multiple string to a command line option Seems like self.ptype is a type that has __init__ with no arguments (other than self).

passing multiple string to a command line option
Dear developers,
Suppose I have this list in command line options:
... -b b1,b2,b3
Here is what I wrote:
parser = optparse.OptionParser()
# Benchmark options
parser.add_option(-b, --benchmark, default=, help=The benchmark to be
loaded.)
process = []
benchmarks = options.benchmark.split(',')
for bench_name in benchmarks:
process.append(bench_name)
At this stage, I want to bind each process to something:
np = 2
for i in xrange(np):
...
system.cpu[i].workload = process[i]
however I get this error:
File configs/example/cmp.py, line 81, in module
system.cpu[i].workload = process[i]
File /home/mahmood/gem5/src/python/m5/SimObject.py, line 627, in __setattr__
value = param.convert(value)
File /home/mahmood/gem5/src/python/m5/params.py, line 236, in convert
tmp_list = [ ParamDesc.convert(self, value) ]
File /home/mahmood/gem5/src/python/m5/params.py, line 159, in convert
return self.ptype(value)
TypeError: __init__() takes exactly 1 argument (2 given)
Error setting param TmpClass.workload to bzip2_chicken
params.py is part of the simulator and I didn't wrote that.
My question is what is the simplest way to fix that?
Or is there any better idea than what I did in order to parse such command line
option?
thanks

If you are starting a new project, consider using argparse, which has
superceded optparse.

Re: passing multiple string to a command line option
As far as I see, the problem is not in the command line but in system.cpu[i].workload = process[i] call tree. Without seeing the code of SimObject and params I can't tell much more. -- http://mail.python.org/mailman/listinfo/python-list

File /home/mahmood/gem5/src/python/m5/params.py, line 159, in convert
return self.ptype(value)
following is part of params.py and I marked line 159.
I didn't wrote this code so changing this may cause problem with other files.
If there is an alternative for doing such thing passing multiple strings to
command line option, it is much better.
# Regular parameter description.

file_ext = 'ptype'

if ptype != None:
self.ptype = ptype
if args:
if len(args) == 1:
self.desc = args[0]
elif len(args) == 2:
self.default = args[0]
self.desc = args[1]
else:
raise TypeError, 'too many arguments'
if kwargs.has_key('desc'):
assert(not hasattr(self, 'desc'))
self.desc = kwargs['desc']
del kwargs['desc']
if kwargs.has_key('default'):
assert(not hasattr(self, 'default'))
self.default = kwargs['default']
del kwargs['default']
if kwargs:
raise TypeError, 'extra unknown kwargs %s' % kwargs
if not hasattr(self, 'desc'):
raise TypeError, 'desc attribute missing'
def __getattr__(self, attr):
if attr == 'ptype':
ptype = SimObject.allClasses[self.ptype_str]
assert isSimObjectClass(ptype)
self.ptype = ptype
return ptype
raise AttributeError, '%s' object has no attribute '%s' % \
(type(self).__name__, attr)
def convert(self, value):
if isinstance(value, proxy.BaseProxy):
value.set_param_desc(self)
return value
if not hasattr(self, 'ptype') and isNullPointer(value):
# deferred evaluation of SimObject; continue to defer if
# we're just assigning a null pointer
return value
if isinstance(value, self.ptype):
return value
if isNullPointer(value) and isSimObjectClass(self.ptype):
return value
return self.ptype(value) # LINE 159
