QUESTION
I`m using python poetry(https://python-poetry.org/) for dependency management in my project.
Though when I`m running poetry install
, its giving me below error.
ANSWER
Answered 2022-Jan-03 at 13:24I solved it by doing the following steps:-
I updated the pyproject.toml(This file contains all the library/dependency/dev dependency)with the numpy version that I installed using

to update poetry.lock file(contains details information about the library)Run
poetry install
again, & it should work fine.

QUESTION
I need to calculate the square root of some numbers, for example √9 = 3
and √2 = 1.4142
. How can I do it in Python?
The inputs will probably be all positive integers, and relatively small (say less than a billion), but just in case they're not, is there anything that might break?

Note: This is an attempt at a canonical question after a discussion on Meta about an existing question with the same title.
...ANSWER
Answered 2022-Feb-04 at 19:44math.sqrt()
The math
module from the standard library has a sqrt
function to calculate the square root of a number. It takes any type that can be converted to float
(which includes int
) as an argument and returns a float
.
QUESTION
I just downloaded pytube (version 11.0.1) and started with this code snippet from here:
...ANSWER
Answered 2021-Nov-22 at 07:03Found this issue, pytube v11.0.1. It's a little late for me, but if no one has submitted a fix tomorrow I'll check it out.
in C:\Python38\lib\site-packages\pytube\parser.py
Change this line:
152: func_regex = re.compile(r"function\([^)]+\)")
to this:
152: func_regex = re.compile(r"function\([^)]?\)")
The issue is that the regex expects a function with an argument, but I guess youtube added some src that includes non-paramterized functions.

command for my Python 2.7 App Engine project.

component to the previous version
QUESTION
I am getting an error when trying to save a model with data augmentation layers with Tensorflow version 2.7.0.
Here is the code of data augmentation:
...ANSWER
Answered 2022-Feb-04 at 17:25This seems to be a bug in Tensorflow 2.7 when using model.save
combined with the parameter save_format="tf"
, which is set by default. The layers RandomFlip
, RandomRotation
, RandomZoom
, and RandomContrast
are causing the problems, since they are not serializable. Interestingly, the Rescaling
layer can be saved without any problems. A workaround would be to simply save your model with the older Keras H5 format model.save("test", save_format='h5')

QUESTION
I know Python //
rounds towards negative infinity and in C++ /
is truncating, rounding towards 0.
And here's what I know so far:
...ANSWER
Answered 2022-Jan-18 at 21:46Although I can't provide a formal definition of why/how the rounding modes were chosen as they were, the citation about compatibility with the %
operator, which you have included, does make sense when you consider that %
is not quite the same thing in C++ and Python.
In C++, it is the remainder operator, whereas, in Python, it is the modulus operator – and, when the two operands have different signs, these aren't necessarily the same thing. There are some fine explanations of the difference between these operators in the answers to: What's the difference between “mod” and “remainder”?
Now, considering this difference, the rounding (truncation) modes for integer division have to be as they are in the two languages, to ensure that the relationship you quoted, (m/n)*n + m%n == m
, remains valid.
Here are two short programs that demonstrate this in action (please forgive my somewhat naïve Python code – I'm a beginner in that language):

QUESTION
I have built a pixel classifier for images, and for each pixel in the image, I want to define to which pre-defined color cluster it belongs. It works, but at some 5 minutes per image, I think I am doing something unpythonic that can for sure be optimized.
How can we map the function directly over the list of lists?
...ANSWER
Answered 2021-Jul-23 at 07:41Just quick speedups:
- You can omit
math.sqrt()
- Create dictionary of colors instead of a list (that way you don't have to search for the index each iteration)
- use
min()
instead ofsorted()
QUESTION
I'm trying to communicate with an OPC DA server and need to write in a tag which is in an array format. We can connect with a simulation server, read tags (int, real, array) and write tags (int, real, str). The problem comes when we need to write in an array tag. The developper of the OpenOPC library (Barry Barnreiter) recommand to use a VARIANT variable because OPC "expect to see a Windows VARIANT structure when writing complex objects such as arrays".
- I did install Pywin32 (build 217) as suggested here.
- I tried to send a simple integer instead of an array in a VARIANT structure.
Here's the code:
...ANSWER
Answered 2021-Dec-05 at 19:56You need to upgrade the python
to 3.9
and Pywin32
to Build 302
. In addition, you need to install the OpenOPC-Python3x 1.3.1
.
QUESTION
Since updating to python@3.9.8
we get an error while using Black in our CI pipeline.
ANSWER
Answered 2021-Nov-17 at 08:17The initial error was a failing python Black pipeline. Black failed because it was pinned to an older version which now fails with python3.9.8
.
Updating black to the latest version 21.10b0 fixed the error for me.
See also typed_ast issue #169:
For others who may find this in a search, I ran into this problem via black because I had black pinned to an older version. The current version of black appears to no longer use typed-ast and thus won't encounter this issue.
Update:
using the latest typed-ast
version >=1.5.0
seem to work as well
e.g. pip install typed-ast --upgrade

Install python-
You can use python- like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
