AttributeError: 'module' object has no attribute 'disable_autoreload'

im trying to disable auto update in Circutpython 8.0 beta on the pico W and every time I run
import supervisor supervisor.disable_autoreload()
I always get this error
>>> supervisor.disable_autoreload() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no attribute 'disable_autoreload'
how can I fix this

I had the same issue and I'm not sure why because this function is still in the official documentation. Anyways, this worked for me on en_US-8.0.0-rc.2.
supervisor.runtime.autoreload = False

Cannot run python-escpos methods

I have an Epson thermal printer (TM-82), connected via USB. I am using python-escpos library (version v2.2.0) I am trying to run some of Escpos module's methods such has ln(), textln(), etc. But none of these commands work, and I get an error 'Usb' object has no attribute <method_name>. The only commands that work are text(), qrcode(), barcode(), image() and cut().
Can you guys please tell me what's wrong?
Steps to reproduce
>>> from escpos import printer
>>> p = printer.Usb(0x04b8, 0x0e11, 0)
>>> p.text('hello')
>>> p.ln()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Usb' object has no attribute 'ln'
>>> p.is_online()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Usb' object has no attribute 'is_online'

If you are using python-escpos 2.2.0, look at the source and documentation for that version.
There is no ln or is_online function in that version.

AttributeError: class Prolog has no attribute 'dynamic'

I've installed pyswip on ubuntu and I followed the official documentation to do so. However, I'm still getting some issues, I found some workarounds for a couple of them and I'm still fighting with more.
Here is the code and error I'm currently getting:
>>> from pyswip import Prolog, registerForeign, Variable, Functor
>>> registerForeign(ask_question,name='ask', arity=1)
1
>>> hypothesize = Functor("hypothesize",1)
>>> Test = Variable()
>>> assertz = Functor('assertz',1)
>>> Prolog.dynamic("yes/1, no/1")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: class Prolog has no attribute 'dynamic'
Any thoughts? Thanks!

I can't start successfully boa constructor in windows7

When I start boa-constructor(boa-constructor-0.6.1.src.win32.exe) from the command line by starting the script "Boa.py", I got the message says
My python version is "python-2.7.7.msi" and I download wxPyton "wxPython3.0-win32-3.0.0.0-py27.exe"
O searched for files that contains the string "NO_3D " but I didn't get any can you help me pleaze and thanks

Actually you will require wxPython 2.8.12.1 to not get this error.
>>> import wx
>>> wx.__version__
'2.8.12.1'
>>> wx.NO_3D
0
This is a pity, because the operation …|wx.NO_3D is actually a No-Op. So you could fix this particular issue by defining wx.NO_3D somewhere.
On 2.9.5:
>>> import wx
>>> wx.__version__
'2.9.5.0'
>>> wx.NO_3D
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'NO_3D'

AttributeError: 'module' object has no attribute 'TextCalendar'

When I copy the below code in Ideone then it runs fine but it is not running in the text editor and showing the error mentioned in the subject of this post:
import calendar
c = calendar.TextCalendar(calendar.SUNDAY)
c.prmonth(2007, 7)
The complete error is:
Traceback (most recent call last):
File "calendar.py", line 1, in <module>
import calendar
File "/home/shl/Desktop/calendar.py", line 2, in <module>
c = calendar.TextCalendar(calendar.SUNDAY)
AttributeError: 'module' object has no attribute 'TextCalendar'

change the program name from calendar.py to something like calendar_code.py
This wold work properly.
Importing from builtin library when module with same name exists
