Flask(flask db init): AttributeError: module 'time' has no attribute 'clock'

While following a Flask tutorial I stumbled around this very strange problem! While setting up the Migrate directory , after the first step of setting the flask app using set FLASK_APP=sql1.py, when I ran this command flask db init I got this error:

AttributeError: module 'time' has no attribute 'clock'
I'm getting the exact same error while running my .py script also,here's the script:
from flask import Flask

from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
basedir = os.path.abspath(os.path.dirname(__file__)) #Full directory path of the file I'm working with..here, sql1.py
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'data.sqlite')
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
db = SQLAlchemy(app)
Migrate(app,db) #Here it connect the application "app.py"
# with the database "db"
class puppy(db.Model):
__tablename__ = 'Name Provided by me!!'
id = db.Column(db.Integer,primary_key = True)
name = db.Column(db.Text)
age = db.Column(db.Integer)
def __init__(self,name,age):
self.name = name
self.age = age
def __repr__(self):
return f"puppy {self.name} is {self.age} year/s old!"
I looked into every solution I found (here and this)and made sure everything was correct! I ran this command when my environment was activated which had installed every package needed including SQLAlchemy and Flask-Migrate.
I even deleted them (packages) and re-installed their latest versions but still getting the same error!
I'm using Python 3.8.5

You have some dependencies that are too old and incompatible with Python 3.8. At the very least, you should update the mako package:
pip install --upgrade mako

I had a similar issue I had to update flask_sqlalchemy even after doing this I had issues. I ended up having to make a new virtual environment, I would make a small hello world project on another virtual environment to see if that works.

For me, it was giving the same error, so I removed __init__.py file from the folder which has app.py
After removing I ran the
flask init db
it worked :)

Atom `script` add-on doesn't recognize Django Model/settings when running a script

It seems I run into some dependencies issues when trying to run a python script within my Django based web application using the atom add-on script.
I would like to run the following script using the Atom script add-on:
feeder.py:
import zmq
import time
from time import sleep
import uuid
from models import AccountInformation
context = zmq.Context()
zmq_socket = context.socket(zmq.PULL)
zmq_socket.bind("tcp://*:32225")
time.sleep(1)
while True:
try:
msg = zmq_socket.recv_string()
data = msg.split("|")
print(data)
if (data[0] == "account_info"):
version = data[1]
DID = uuid.UUID(data[2])
accountNumber = int(data[3])
broker = data[4]
leverage = data[5]
account_balance = float(data[6])
account_profit = float(data[7])
account_equity = float(data[8])
account_margin = float(data[9])
account_margin_free = float(data[10])
account_margin_level = float(data[11])
account_currency = data[12]
feed = AccountInformation(
version=version,
DID=DID,
accountNumber=accountNumber,
broker=broker,
leverage=leverage,
account_balance=account_balance,
account_pofit=account_profit,
account_equity=account_equity,
account_margin=account_margin,
account_margin_free=account_margin_free,
account_margin_level=account_margin_level,
account_currency=account_currency
)
feed.save()
# Push data to account information table
else:
print("no data")
except zmq.error.Again:
print("\nResource timeout.. please try again.")
sleep(0.000001)
Unfortunately it raises the following error:

[Finished in 0.302s]
When I remove the model import everything just runs fine, it just won't populate my DB then since I need the imported model...
How to possibly solve this?

Your models are inside your apps, and your apps are inside your settings (INSTALLED_APPS), so you should configure the django's settings before you can access them.
Just add these before importing your models:
import django
django.setup()
You should also set DJANGO_SETTINGS_MODULE environment varialbe to specify your settings file; or use django.configure if you prefer (docs).

spark-submit python file ‘home/.python-eggs’ permission denied

I had a problem when I use spark-submit to run a python file.When the 'map' code run in 'executor', the problem like this :

pkg_resources.ExtractionError: Can't extract file(s) to egg cache
The following error occurred while trying to extract file(s) to the Python egg
cache:
[Errno 13] Permission denied: '/home/.python-eggs'
The Python egg cache directory is currently set to:
/home/.python-eggs
Perhaps your account does not have write access to this directory? You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.
I set the PYTHON_EGG_CACHE environment variable to every executor,and I also write 'os.environ['PYTHON_EGG_CACHE'] = "/tmp/"' in my program,but the problem is still happen.
My code :
import os,sys
print "env::::"+os.environ['PYTHON_EGG_CACHE']
from pyspark import SparkConf, SparkContext
# Load and parse the data
def parsePoint(line):
import os
print "env::::"+os.environ['PYTHON_EGG_CACHE']
os.environ['PYTHON_EGG_CACHE'] = "/tmp/"
values = [float(x) for x in line.split(' ')]
return line
if __name__ == "__main__":
os.environ['PYTHON_EGG_CACHE'] = "/tmp/"
print "env::::"+os.environ['PYTHON_EGG_CACHE']
conf = SparkConf()
sc = SparkContext(conf = conf)
data = sc.textFile(sys.argv[1])
parsedData = data.map(parsePoint)
parsedData.collect()
I run this python program in 'standalone' model and succeeded.
This is my submit command:
spark-submit --name test_py --master yarn-client testpy.py input/sample_svm_data.txt
Is the yarn's problem?

This is late, but it's the first result # google I found with this problem... the previous answer is helpful (i wanted to know which env vars I had to modify), but please DONT modify editing Spark sources, just change environment variables using the proper tools, add this to your spark.conf variables...
spark.executorEnv.PYTHON_EGG_CACHE="./.python-eggs/"
spark.executorEnv.PYTHON_EGG_DIR="./.python-eggs/"
spark.driverEnv.PYTHON_EGG_CACHE="./.python-eggs/"
spark.driverEnv.PYTHON_EGG_DIR="./.python-eggs/"
(I prefer not to use /tmp/ because . will get deleted after my job ends, so eggs should disappear too IMO)

I solved this problem：
unzip the pyspark.zip then find rdd.py file
open this file , under "import os" line ,add code as :
os.environ['PYTHON_EGG_CACHE'] = '/tmp/.python-eggs/'
os.environ['PYTHON_EGG_DIR']='/tmp/.python-eggs/'
save file and zip pyspark

I solved this problem with the help from BiS's answer. By adding the four configuration values when running spark-submit, it fixed the egg problem.
Here's an example of what adding the four parameters looks like when using spark-submit.
spark-submit \
--conf spark.executorEnv.PYTHON_EGG_CACHE="./.python-eggs/" \
--conf spark.executorEnv.PYTHON_EGG_DIR="./.python-eggs/" \
--conf spark.driverEnv.PYTHON_EGG_CACHE="./.python-eggs/" \
--conf spark.driverEnv.PYTHON_EGG_DIR="./.python-eggs/" \

What can it be the problem? I have django in directory C:\Python27\Lib\site-packages\django\db and in there i have a file called models.
This is the pic
Bizarre isn't it?

Not all of Django supports simply being loaded as a Python module, unfortunately; you need to use the means provided by Django itself to bootstrap the environment needed to load stuff like models.
One option is to use the Django shell but it's also possible to use a purely programmatic solution from your own code. See https://docs.djangoproject.com/en/dev/topics/settings/ for all the options.
Here's also an example by somebody else https://gist.github.com/jordanorelli/1025419 but I haven't verified if it's up to date.

The answer is in the error message:
You must either define the environment variable DJANGO_SETTINGS_MODULE or...
For this reason Django provides a shortcut to loading a python shell with Django settings configured:

Using a Django model from a mercurial python hook

I'm trying to queue up some build requests in a DB during a changegroup hook. The DB table is managed by a Django app. So, in the hook, I want to use the Django model to submit the build request. However, I'm unable to get my settings right to import the model successfully.
Based on this (https://docs.djangoproject.com/en/1.3/ref/django-admin/) info, all I need to do is add my django site to the sys path, and set the DJANGO_SETTINGS_MODULE. The django site lives in /opt/mysite, so - trying this from the python console:
>>> import sys
>>> import os
>>> sys.path.append('/opt')
>>> os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
>>> from mysite.myapp.models import Build
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

File "/usr/lib/pymodules/python2.7/django/db/backends/mysql/base.py", line 28, in <module>
from django.db import utils
ImportError: cannot import name utils
>>>
Second Attempt:
Based on this (http://www.b-list.org/weblog/2007/sep/22/standalone-django-scripts/) I can use setup_environ(), when I try this in the python shell, it works:
>>> import sys
>>> sys.path.append('/opt')
>>> from django.core.management import setup_environ
>>> from mysite import settings
>>> setup_environ(settings)
'/opt/mysite'
>>> from mysite.myapp.models import Build
>>> Build.objects.all()
[<Build: #1 F nkj sdfsdfsdfs43qg test_branch>, <Build: #2 F nkj sdfsdfsdfs43qg test_branch>, <Build: #13 Q >, <Build: #14 Q nkj_bug243>, <Build: #11 F nkj 444hwe45hedrrt nkj_bug272>, <Build: #12 F nkj sdfsdfsdfs43qg test_branch>]
However, when I try this in my Mercurial hook, I get blasted with errors the minute I try to import my Build model:
#!/usr/bin/env python
import sys
path = '/opt'
if path not in sys.path:
sys.path.append(path)
from django.core.management import setup_environ
from mysite import settings
setup_environ(settings)
from mysite.myapp.models import Build
import datetime
... do stuff ...
When it gets to the 'from mysite.myapp.models import Build' line I get the following error output:

Any ideas as to what could be causing this problem?

The DictConfigurator error is a bug in python, hopefully fixed in the next 2.7 release (http://bugs.python.org/issue12718), something (probably mercurial) is overriding import and python's logging code fails in that case.
Until then here is what I did to fix it. Copy dictconfig.py from django/utils to somewhere in your python system path (I put it alongside my hook). Change the line
importer = __import__
to:
def importer(self, *args):
return __import(*args)__
And then in settings.py for your django project add to the end:
LOGGING_CONFIG = 'website.dictconfig.dictConfig'
Update website.dictconfig to whatever path you put the dictconfig file into so python can find it.
UPDATE: I think there is an even easier way. Add this to the top of your hook script, before importing anything else:
from mercurial import demandimport;
demandimport.disable()
This makes Mercurial revert the import override and seems to solve the problem cleanly.

If you're running with your environment in a virtualenv dir you'll need to add that to the site packages and I'd also suggest that you put the django dir at the front of sys.path instead of the end.
Here's the code we use to integrate our Django app into other python apps.
import os
import sys
# point this at the virtualenv dir that your django deployment runs out of
# you are using virtualenv. right?
DJANGO_ENV = '/home/core/python-envs/production'
# where your code lives (ie where settings.py is)
DJANGO_DIR = '/home/core/code/production'
# add our site packages
import site
site_packages = os.path.join(DJANGO_ENV, 'lib', 'python%s' % sys.version[:3], 'site-packages')
site.addsitedir(site_packages)
# put the main Django directory on first
sys.path.insert(0, DJANGO_DIR)
# setup the Django environment pointing to our settings
import settings
import django.core.management
django.core.management.setup_environ(settings)
# finally, import our objects
from yourapp.models import YourModel
One last thing to note is that when we import our code into some applications we've run into scoping issues and imports clashing. To get around it we wrap the work we want to do in a function so that it gets its own scope.
For example, instead of:
from yourapp.models import YourModel
objs = YourModel.objects.filter(something=True)
...
Do something like:
def do_work():
from yourapp.models import YourModel
objs = YourModel.objects.filter(something=True)
...
do_work()
