Whats problem? run python3.6 an error occurred
I just try to pdb on Cygwin.
(Note that other lib is okay)
In my case the problem was fixed by installing pyreadline:
pip install pyreadline
Please try it.

I have the newest torch installed, and my CUDA version is 11.7, so I chose the closest one torch1.12.1+cu116. However, it does not have PY3 or PY37... Can anyone help me with that? The code that I need to use has PY37 and I don't know how to make the code run...

while studying the open source repo of Odoo I found a line of code that I don't understand like the following
[data] = self.read()
found there https://github.com/odoo/odoo/blob/8f297c9d5f6d31370797d64fee5ca9d779f14b81/addons/hr_holidays/wizard/hr_holidays_summary_department.py#L25
I really would like to know why would you put the variable in a list
It seems to ensure that [data] is an iterable of one item and therefore unpacks the first value from self.read()
It cannot be assigned to a non-iterable
>>> [data] = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot unpack non-iterable int object
Works for iterable types, though must have a length equal to one

>>> data
'some'

Been trying to get this to work for a few hours now. Nothing I try is splitting this text up. I only want the Current CPU from this

It looks mostly like you're ignoring your error messages:
>>> cpu = psutil.cpu_freq()
>>> cpu = cpu.split('current=')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'scpufreq' object has no attribute 'split'
The return value from psutil.cpu_freq() isn't a string, so it doesn't have a split method. If you just print the value...
>>> cpu
scpufreq(current=700.0, min=700.0, max=800.0)
...you get some idea of what attributes it has, and indeed, we can access those values like this:
>>> cpu.current
700.0
>>> cpu.max
800.0
When you set percpu=True, you're getting back a list:
>>> psutil.cpu_freq(percpu=True)
[scpufreq(current=600.0, min=600.0, max=1500.0)]
And once again, a list isn't a string, so there's no split method. Since there's only a single CPU, you get back a 1-item list, so you can access values like this:
>>> cpu = psutil.cpu_freq(percpu=True)
>>> cpu[0].current
700.0
With Python 2, creating a Decimal with an invalid string produces a useful error message:
>>> import decimal
>>> decimal.Decimal('spam')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/decimal.py", line 547, in __new__

decimal.InvalidOperation: Invalid literal for Decimal: 'spam'
While Python 3 produces a not-so-helpful message:
>>> import decimal
>>> decimal.Decimal('spam')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
decimal.InvalidOperation: [<class 'decimal.ConversionSyntax'>]
Is there any way to get a useful message like "Invalid literal for Decimal: 'spam'" from the exception in Python 3?
I'm using Python 2.7.15 and Python 3.7.2, both on darwin.
Addenda:
It looks like Python 2 once had a not-very-helpful message for decimal.InvalidOperation: https://bugs.python.org/issue1770009
This situation looks analogous but most of it goes over my head: https://bugs.python.org/issue21227
You could monkey-patch the decimal module.
import decimal
def safe_decimal(something):
try:
funct_holder(something)
except Exception as e:
new_errror = Exception("Hey silly that's not a decimal, what should I do with this? {}".format(something))
raise new_errror from None
funct_holder = decimal.Decimal
decimal.Decimal = safe_decimal
Then you could use the monkey patched version as so
>>> decimal.Decimal('hello')
Traceback (most recent call last):
File "<input>", line 12, in <module>
File "<input>", line 6, in safe_decimal
Exception: Hey silly that's not a decimal, what should I do with this? hello

In fact I can see some socket lib in:

EDIT:
Can't import socket (same for thread)

Adding /home/emc/py36/lib/python3.6/site-packages to PYTHONPATH solved problem.
I had a similar problem after building 3.7.4 with prefix=/usr/local
Fix was to add to .bashrc the two lines:
export PYTHONHOME=/usr/local
export PYTHONPATH=/usr/local/lib64/python3.7/lib-dynload
