I want to run parallel processing, using the class but the code gives this error :
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\Users\MonPc\AppData\Local\Programs\Python\Python37\lib\multiprocessing\spawn.py", line 105, in spawn_main

File "C:\Users\MonPc\AppData\Local\Programs\Python\Python37\lib\multiprocessing\spawn.py", line 115, in _main
self = reduction.pickle.load(from_parent)
EOFError: Ran out of input
This is just similar to the original code that I want to work on.
MyCode :
from multiprocessing import Process
class class1:
def __init__(self):
super().__init__()
txt = "Rachid"
p1 = class2(txt)
p1.start()
p1.join()
class class2(Process):
def __init__(self, txt):
Process.__init__(self)
self.txt = txt
def run (self):
print("*"*10)
print(self.txt)
print("*"*10)
class1()
How can I avoid getting this error ?
this is my code:
self.msg_entry = Entry(bottom_label, bg="#2C3E50", fg=TEXT_COLOR, font=FONT)
self.msg_entry.place(relwidth=0.74, relheight=0.06, rely=0.008, relx=0.011)
self.msg_entry.focus()
self.msg_entry.bind("<Return>", self._on_enter_pressed)
def _on_enter_pressed(self, event):
msg = self.msg_entry.get()
self._insert_message(msg, "You")
on hovering on on_enter_pressed function, it's showing function is not accessed and I'm getting the following error:
Traceback (most recent call last):
File "GUI.py", line 91, in <module>
app = ChatApplication()
File "GUI.py", line 15, in __init__

self.msg_entry.bind("<Return>", self._on_enter_pressed)
AttributeError: 'ChatApplication' object has no attribute '_on_enter_pressed'
(I'm using tkinter in python to implement GUI.)
How can I solve this?
You have wrong indentations - _on_enter_pressed has to be outside __init__
def __init__(self):
# ... code ..
self.msg_entry = Entry(bottom_label, bg="#2C3E50", fg=TEXT_COLOR, font=FONT)
self.msg_entry.place(relwidth=0.74, relheight=0.06, rely=0.008, relx=0.011)
self.msg_entry.focus()
self.msg_entry.bind("<Return>", self._on_enter_pressed)
# outside `__init__`
def _on_enter_pressed(self, event):
msg = self.msg_entry.get()
self._insert_message(msg, "You")
I am trying to create a tkinter label that changes color when clicked to show that it has been visited. I keep getting an attribute error saying that Show_Label has no attribute 'fg'. Please help! Here is the code being used.
class Sheet_Label(Label):
def __init__(self,master,text):
Label.__init__(self,master,text=text,cursor="hand2",font="Times 16 underline",fg="blue")
def button_click(event):
if self.fg =="blue":
self.fg = "purple"
else:
self.fg = "purple"
location = os.getcwd()
file = webbrowser.open_new(location + '\\' + "hello.txt")
self.bind("<Button-1>",func=button_click)
def sheets_view():
sheets_window = Toplevel(window)
hello = modules.Sheet_Label(master=sheets_window,text="Hello")
hello.pack(padx=10,pady=10)
sheets_window.title("Production Sheets")
sheets_window.focus()
x = (screen_width/2) - (500/2)
y = (screen_height/2) - (500/2)
sheets_window.geometry("%dx%d+%d+%d" % (500,500,x,y))
sheets_window.resizable(0,0)
Here is the error message:

You aren't initializing self.fg until button_click has been called, but at that point it's too late because you're trying to reference self.fg before setting it.
Also, self.fg is not the same as the fg attribute when you create the widget (eg: Label(..., fg="blue"). If you want to get the value of the widget attribute you should use self.cget('fg') or use the shortcut self['fg']. If you want to set it from within the class itself you should use self.configure(fg="purple").
I defined a function in my class, but when i called this function into my main program:
class real :
def __init__(self):
self.nmodes = 4
self.L_ch = 1
self.w = 2
def func1(self,x):
self.k_ch=self.nmodes*self.L_ch*self.w
f=x**3+4*x*self.k_ch+15*self.k_ch
return f
And my main program is:
from dev import *
A=real()
C=A.func1(x)
Unfortunately i got this error:
Traceback (most recent call last):
File "PBC.py", line 4, in <module>
C=A.func1(0.2)
AttributeError: real instance has no attribute 'func1'
When i don't include the function in my class, my parameters are not recognized and i got this error:
Traceback (most recent call last):
File "PBC.py", line 75, in <module>
R_0=scipy.optimize.fsolve(func1,float(eps_real),args=(eps))

What can i do to avoid all this? Thank you for your answers.
Your above code runs if you just fix the indentation:
class real :
def __init__(self):
self.nmodes = 4
self.L_ch = 1
self.w = 2
def func1(self,x):
self.k_ch=self.nmodes*self.L_ch*self.w
f=x**3+4*x*self.k_ch+15*self.k_ch
return f
A=real()
C=A.func1(5)
You have an indentation error. The lines starting def func1 should be lined up with def __init__.
I have a problem with my python code specialy when I'm trying to define a function in a Class. Indeed, I want to call this function (which is in a file i called BC.py) in my main program which i called PBC.py
Class BC():
self.nmodes
self.L_ch
self.w
def func1(self,x):
self.k_ch=self.nmodes*self.L_ch*self.w
f=x**3+4*x*self.k_ch+15*self.k_ch
return f
In my main programm i did:
from BC import *
A=BC()
C=func1(self,x)
Then I got this error:
The parameters file have been imported succesfully
Traceback (most recent call last):
File "PBC.py", line 35, in <module>
C =func1(A,eps)
NameError: name 'func1' is not defined
Please do you know where i am wrong?
The thing is, when i don't include the function in my class everything works well,
Class BC():
self.nmodes
self.L_ch
self.w
def func1(self,x):
self.k_ch=self.nmodes*self.L_ch*self.w
f=x**3+4*x+15
return f
Exept that when i use only the function, all the parameters I defined before are not recognized???
For example:
r_0=scipy.optimize.fsolve(func1,0.003,args=(0.032))
I got this error:
The parameters file have been imported succesfully
Traceback (most recent call last):
File "PBC.py", line 75, in <module>
R_0=scipy.optimize.fsolve(func1,float(eps_real),args=(eps))
File "/usr/local/lib64/python2.7/site-packages/scipy/optimize/minpack.py", line 127, in fsolve
res = _root_hybr(func, x0, args, jac=fprime, **options)
File "/usr/local/lib64/python2.7/site-packages/scipy/optimize/minpack.py", line 183, in _root_hybr
_check_func('fsolve', 'func', func, x0, args, n, (n,))
File "/usr/local/lib64/python2.7/site-packages/scipy/optimize/minpack.py", line 14, in _check_func
res = atleast_1d(thefunc(*((x0[:numinputs],) + args)))
File "/home/cfd1/ndiaye/ATACAMAC/BCT_dev.py", line 75, in func1
self.k_ch=self.nmodes*self.pi/self.L_ch+eps/self.L_ch
AttributeError: 'numpy.ndarray' object has no attribute 'nmodes'
Someone can help?
Thank you very much.
Thank you for your answer but it isn't working, i still got this error:
Traceback (most recent call last):
File "PBC.py", line 36, in <module>
C =A.func1(x)
Now i'm trying with a very simplified script:
class real :
def __init__(self):
self.nmodes = 4
self.L_ch = 1
self.w = 2
def func1(self,x):
self.k_ch=self.nmodes*self.L_ch*self.w
f=x**3+4*x*self.k_ch+15*self.k_ch
return f
And my main program is:
from dev import *
A=real()
C=A.func1(x)
Unfortunately it seems not working to caus' i have the same traceback error.
Thank you.
You should call it this way:
from BC import *
A=BC()
C=A.func1(x)
Edit for comment:
Please take care of the code format:
class real :
def __init__(self):
self.nmodes = 4
self.L_ch = 1
self.w = 2
def func1(self,x):
self.k_ch=self.nmodes*self.L_ch*self.w
f=x**3+4*x*self.k_ch+15*self.k_ch
return f
Call the function this way (recommended):
A = BC()
C = A.func1(x)
or this other (less used and not recommended, just mentioned as information):
C = BC.func1(A, x)
Note: I would recommend you to rename your file with a name different than the class BC, because it confuses Python. Also, don't forget to declare x.
