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

I am trying to load my json file. I am new to MacOS,but that should be the problem. My code
from terminal
import json
>>> with open('ticr_calculated_3_2020-05-27T11-01-30.json','r+', encoding='utf-8') as f:
data=json.load(f)
I got error
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
AttributeError: '_io.TextIOWrapper' object has no attribute 'load'
The same error happens with json example from Python docs
json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: '_io.TextIOWrapper' object has no attribute 'dumps'
Why?
Have you written everything into one Python interpreter session? It seems to me that you defined the name json before.
Try opening a new Python interpreter or writing your script into a file.
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.
This is my code:
from nltk import load_parser
cp = load_parser('grammars/book_grammars/sql0.fcfg')
query = 'What cities are located in China'
trees = cp.parse(query.split())
answer = trees[0].node['sem']
Here is the error message:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'generator' object has no attribute '__getitem__'
Why it is giving such error, what is the solution of it?
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
Using python-spidermonkey in the following way (following the guide) gives me the error AttributeError: 'spidermonkey.Context' object has not attribute 'eval_script'.

>>> cx.eval_script("1 + 2") + 3
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'spidermonkey.Context' object has no attribute 'eval_script'

Installing this package on Ubuntu (12.10) worked for me:
