I am trying to use flask dotenv along with python-dotenv but I noticed that there is an inssue on Windwos 10.
Everyting works fine on Mac,Linux but on windows when I run the flask application I get an exception.
It seams that the issue is with the file .flaskenv. If I rename the file from .flaskenv to _flaskenv there is no exception anymore but my env variables are not defined. I have tried to also to load manually this file but without any success. the _flaskenv is not loaded.
# .flaskenv
FLASK_APP=manage.py
FLASK_ENV=development
PS D:\practice\flask-dotenv> flask run

I'm running vscode debugger inside Docker container but it started showing an error:
That is very strange because when I open python shell in the same vscode window and import the same module import works just fine. So I need to find the reason why debugger doesn't see the modules

Finally I found the source of this issue - it was in the file that directly imported to docker-entry file and modules from project directories were imported in a strange way:
# This line adds to modules imports that added below cd two levels up
sys.path.insert(0, os.path.dirname(__file__) + "/../..")
import honkio
However, right after I change this file in vs code, formatter changed lines order automatically placing that line at the bottom of all the other imports. Therefore file imports break and it shows module not found error
I am new to python and attempting to setup up a mono repo using pants as the build system. All has been going well, until I told pants to use a python 3 interpreter by setting in pants.ini
[python-setup]
interpreter_constraints: ["CPython>=3.6.5"]
I have a setup a local library python_library which is imported into a python_binary.
In other words, for an identical code base,
running ./pants run ... on python 2.7 works perfectly
running ./pants run ... with the above interpreter_constraints fails with ModuleNotFoundError
The stack trace I am getting looks like

What's the bad magic number error?

Closed 4 years ago.
Take it easy, I'm a n00b. I get this error when I'm trying to initialize an environment to get a project going. I've scoured through many stack overflow and GitHub (Usage/request) before I decided to post here. I updated pipenv and even updated by python up to 3.7 from 3.6. I've been at it for 2 hours but I decided I may need your help.

Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

I used anaconda + python 3.6.5 and I installed git and set path with C:\Program Files\Git\bin\git.exe and C:\Program Files\Git\cmd.
I installed mlflow whit pip install mlflow and its version is 0.2.1.
I set a variable with name GIT_PYTHON_GIT_EXECUTABLE and value C:\Program Files\Git\bin\git.exe in Environment Variables.
How can I solve this?
firstly Uninstall 'mlflow' and 'waitress', then again install 'mlflow' .Now try it works
mlflow documentation already says that
Note 2: We do not currently support running MLflow on Windows.
Despite this, we would appreciate any contributions to make MLflow
work better on Windows.
You're hitting fcntl problem: it's not available on MS Windows platform because it's a "wrapper" around the fcntl function that's available on POSIX-compatible systems. (See https://stackoverflow.com/a/1422436/236007 for more details.)
Solving this requires modifying the source code of mlflow accordingly.
Following the Flask 0.11 documentation, I cloned the Flask repo, created a virtualenv, and installed Flask via pip install flask. I went into the examples/flaskr directory, set the FLASK_APP environment variable, then executed:
flask run

How do I correctly run the flaskr example?
I was setting FLASK_APP=flaskr. Since I hadn't installed my app as a package in my virtualenv, I needed to add the .py extension.
export FLASK_APP=flaskr.py
Flask issue for the eclipse and PyDev extension, you can set a path like this.
Flask 1.0.2 and Python 3.6 already installed on Windows 10.

Run Flask in proper folder path to resolve this issue.
