I'm working on a project, using openmodelica. I'm trying to simulate the system multiple times and i wrote a python script to automatize it. I also override parameters on each iteration of the simulation, but if i try to override an array i'll get this on console:
Traceback (most recent call last):
File "pythonScripts/testing.py", line 164, in <module>
startSimulation(5,2,1,4, noFault,flyZone[1])
File "pythonScripts/testing.py", line 118, in startSimulation
vars = omc.sendExpression("readSimulationResult(\"System_res.mat\",{time})")
File "/home/francesco/.local/lib/python3.8/site-packages/OMPython/__init__.py", line 779, in sendExpression
answer = OMTypedParser.parseString(result)
File "/home/francesco/.local/lib/python3.8/site-packages/OMPython/OMTypedParser.py", line 120, in parseString
res = omcGrammar.parseString(string)
File "/home/francesco/.local/lib/python3.8/site-packages/pyparsing/core.py", line 1143, in parse_string
raise exc.with_traceback(None)
pyparsing.exceptions.ParseException: Expected end of text, found '(' (at char 4), (line:1, col:5)
This is an example of how i did it:
def startSimulation(n, intr, miss, statObs, fault, flyZone):
with open("newValues.txt", 'wt') as f:
f.write("const.N="+str(n)+"\n")
f.write("const.nIntr="+str(intr)+"\n")
f.write("const.nRocket="+str(miss)+"\n")
f.write("const.nStatObs="+str(statObs)+"\n")
f.write("fault.transMatrix[4,4]="+str(fault)+"\n")
f.write("const.flyZone[3]="+flyZone+"\n")
f.flush()
os.fsync(f)
os.system("./System -overrideFile=newValues.txt >> LogOverride")
noFault = "[1, 0, 0, 0; 1, 0, 0, 0; 1, 0, 0, 0; 1, 0, 0, 0]"
flyZone = ["{100,100,100}","{150,150,150}","{200,200,200}"]
startSimulation(5,2,1,4, noFault,flyZone[1])
Any suggestion?
OpenModelica will expand arrays into scalars when the C code is generated so you need to override each of the array elements separately in newValues.txt:
fault.transMatrix[1,1]=1
fault.transMatrix[1,2]=0
fault.transMatrix[1,3]=0
fault.transMatrix[1,4]=0
fault.transMatrix[2,1]=1
fault.transMatrix[2,2]=0
fault.transMatrix[2,3]=0
fault.transMatrix[2,4]=0
...

I have defined a new derived dimension with
[molar_energy] = [energy] / [substance]
However, if I do the following it complains:

KeyError: <UnitsContainer({'[length]': 2, '[mass]': 1, '[substance]': -1, '[time]': -2})
I saw that there is a conversion included in a context but I don't use it. What I am doing wrong?
Thanks for your help
PS: logged issue https://github.com/hgrecco/pint/issues/1418
Just leaving the solution here for anyone who faces this issue as well.
I just added a made-up unit and it worked
# Molar Energy
[molar_energy] = [energy] / [substance]
mol_en = J / mol
I've started working on a curses program in python and I have come across this issue. The code "logo.addstr(count, 1, line)" gives this error:
Traceback (most recent call last):
File "intro.py", line 90, in <module>
curses.wrapper(main)
File "/usr/lib/python3.7/curses/__init__.py", line 102, in wrapper
return func(stdscr, *args, **kwds)
File "intro.py", line 22, in main
show_rank_logo()
File "intro.py", line 87, in show_rank_logo
logo.addstr(count, 1, line)
_curses.error: addwstr() returned ERR
If you replace "count" with 1, the lines will show up but on one line (as it should). This file is ASCII art so I want it to display in the window (named logo) all at once. This is why I added a count to the loop. But the variable which equals 1 somehow gives an error.
def show_rank_logo():
logo = curses.newwin(35, 105, 1, 51)
logo.box()
count = 1
with open('platinum_logo.txt') as file:
for line in file.readlines():
logo.addstr(count, 1, line)
count += 1
logo.refresh()
Looking for any help!
I have written a small python script to read data from a digital thermometer, and everything works just fine in my computer. however, i need to run this same script in other systems, but i keep getting a "[Errno 10060] Operation timed out" error.
in the second computer i can see the device, it's endpoints and everything, but it's when i try to read from it that i'm getting the error.
this is the code (i intentionally did not set the configuration for the device, as i'm trying to speed up the reading, and in my system it proved not to be necessary):
import usb.core
def get_temp(T):
# find our device
dev = usb.core.find(idVendor=0x04d9, idProduct=0xe000)
# was it found?
if dev is None:
raise ValueError('Device not found')
# poll the thermometer for current temperature
t = dev.read(0x83, 32) # gets 32 bytes from ENDPOINT address 0x83
so, in the computer where i wrote this, it works as expected, and it returns a nice 32-byte array. but in other systems, i got the error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\usb\core.py", line 402, in read

_check
raise USBError(_strerror(ret), ret, _libusb_errno[ret])
usb.core.USBError: [Errno 10060] Operation timed out
i tried also setting device configuration this time, but still same error.
any ideas on what i might be missing?
edit: this is my output log with PYUSB_DEBUG environment variable set to debug:

I thought I had found the solution to my probelm (and the code) fro Idan:
MoviePy + Vapory code
from moviepy.editor import concatenate, ImageClip, VideoClip
from vapory import *
img_path = "E:/Programming/Python/coffee.png"
img_clip = ImageClip(img_path)
W, H = img_clip.w, img_clip.h
AR = 1.0*W/H
t_rev = 2.0
t_half = t_rev/2.0 # The time required for a half revolution
t_still = 0.8 # How long (in seconds) to hold the half rotated image still
cam = Camera('location', [ 0, 0, -1],
'look_at', [ 0, 0, 0])
light = LightSource([0, 0, -1]) # Light at camera location
bg = Background('color', [0, 0, 0]) # Black background
def scene(t):
""" Returns the scene at time 't' (in seconds) """
s = Scene(camera = cam, objects = [light, bg])
s = s.add_objects([
Box([0, 0, 0],
[W, H, 0],
Texture(Pigment(ImageMap('"{}"'.format(img_path), 'once')),
Finish('ambient', 1.0)),
'translate', [-0.5, -0.5, 0],
'scale', [AR, 1, 0],
'rotate', [0, (360/t_rev)*t, 0])])
return s
def make_frame(t):
return scene(t).render(width=W, height=H, antialiasing=0.1)
still_1 = VideoClip(make_frame).to_ImageClip(t=0).set_duration(t_still)
half_1 = VideoClip(make_frame).subclip(0, t_half)
still_2 = VideoClip(make_frame).to_ImageClip(t=t_half).set_duration(t_still)
half_2 = VideoClip(make_frame).subclip(t_half, t_rev)
final_clip = concatenate([still_1, half_1, still_2, half_2])
final_clip.write_gif("E:/Programming/Python/coffee_rot.gif", fps=15)
BUT when I try to run it with Python 3.6 I get (full traceback):
Hope this makes things clearer

Could comment re windows file paths be expanded a little?
Ok, I am pretty clueless here. I use the python WMI module to do the following command:
sj = wmi.Win32_ScheduledJob
sj.Create("cmd", 0x40000000, 32, 1, 0, "******153000.000000-420")
And that gives me the following error:
Traceback (most recent call last):
File "<pyshell#56>", line 1, in <module>

Ok, so could you tell me what arguments I am providing wrong? Please give me sample code. Thanks!
Does it make any difference if you format the StartTime argument with 8 initial * characters instead of 6?
I just notice that the Win32_ScheduledJob documentation seems to indicate 8 *s, in place of the omitted YYYYMMDD characters...
