I'm trying to start a flask application, with flask run, (which was working fine before I installed Anaconda), and I'm getting the following stack trace

The Python version at the system level is 3.7.3
The Python version at venv level is 3.7.0
I've already tried to install contextvars, but it only upgraded an older version and did not fix the problem. In both system level and venv level contextvars requisite is already satisfied.
I'm running this on Windows 10.
Any idea on what can be causing this?
I have the same issue when using python 3.7.2 on Windows 7.
This is a known bug and should be resolved.
https://bugs.python.org/issue34691
Updating to python 3.7.3 resolved the issue (for me).
Try to update your venv level to 3.7.3

I try to activate my env to Jupyter notebook by using:
python -m ipykernel install --user --name native --display-name "python-gpu"

It seems like something is wrong with my libsqlite3, but it goes well in my terminal.
My laptop is a Macbook pro with M1Pro. And I'm building an arm64 python environment in M1 version Anaconda.
Does anyone know how I can get around this?
I had the same problem and I solved by installing a newer version:
mamba install sqlite=3.40.0
always checking that the new library is coming from conda-forge/osx-arm64.
I am trying to get the program in this repository to work. If I am on Python version 3.6 then the I have no issues, however, if I am on Python version 3.7 then I get the following error:

All that the __init__.py file contains is this:
from . import region
It seems that region is a .pyx module. Here is the directory structure of it.
How come the import is working fine on Python 3.6, but is unable to import on version 3.7? Both are fresh conda environements, which have not had anything installed apart from opencv, torch + cuda.
I'm a newbie to pre-commit. I'm trying to locally check a single python file I'd staged after I thought I'd had pre-commit installed on my PC (Windows 10) and properly installed in the directory. Here's what happens when I try to commit a file from the git bash shell:
$ git commit -m "test pre-commit"

I installed Anaconda3 on ubuntu and changed the path to ~/anaconda/bin in .bashrc file then I'm trying to install keras It's throwing this error.
hemanth#specter:~$ python3 -m pip install keras

I tried this command and it is working fine.
however, try to install socket using pip install sockets and then again try installing keras.
I'm trying to look around on this issue but so far nothing I've found has fixed it. I am not that familiar with Python and I'm working with someone else's script. I am on Windows 10 (64-bit).
Executing this command: pip install mysql-python

The python module that you are trying to install will probably require you to compile it which makes the task much harder for a newbie.
Instead, I would recommend you to use a pure-python module like https://github.com/PyMySQL/PyMySQL -- which is much easier to install because you do not have to compile it.
Usually I recommend anyone that is trying to work with databases in Python to use SQLAlchemy, mainly because this allows you to use a single interface when you deal with the database, one that does not depends on the database-driver being used.
Read the answer from
