I'm trying to auto generate a schema for use in SQLalchemy, I'm using sqlautocode to do this, I use the following command
D:~ admin$ sqlautocode mysql://'user':"pass"#xx.xx.xx.xx:3306/db_name -o tables.py
but I keep getting the following error..
Traceback (most recent call last):

https://pypi.python.org/pypi/sqlautocode
Use sqlacodegen instead:
D:~ admin$ sqlacodegen mysql://'users':"pass"#xx.xx.xx.xx:3306/db_name --outfile tables.py
this is because you sqlalchemy version is above 07.
find declarative.py in C:\Python27\Lib\site-packages\sqlautocode
change from sqlalchemy.ext.declarative import _deferred_relationship To
from sqlalchemy.ext.declarative.clsregistry import _deferred_relationship
this work in my work.

I received a response from the py5 developer via Github. They also provided an explanation but it goes over my head, something about "The Python library asttokens is used for parsing syntax trees and syntax highlighting. It is not used by py5 but it might be used by Jupyter Notebook and/or JupyterLab.". They also provided a solution here:

I'm getting the exact same error while running my .py script also,here's the script:
from flask import Flask
import os
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 :)
I'm having trouble removing a resource file in a pyqt document, I'm also using monkeystudio IDE. I madea program with images and all linked to a resource file called "resources.qyc" and now I get the error

You'll first have to compile the resource file using pyrcc4. You'll run something like this from command line:
pyrcc4 ResourceFile.qrc -o ui_ResourceFile.py
If I import pgdb just in command line, it works fine.
It was also working fine in Eclipse until recently (with exactly the same Python 2.7.2), but now, when I import pgdb, even in a very simple file (containing just import pgdb), I have this error message:

timestamp = time.mktime(date_time)
AttributeError: 'module' object has no attribute 'mktime'
In fact, more generally, I discovered that if I try from time import mktime, I also have error:
from time import mktime
ImportError: cannot import name mktime
OK, stupid mistake: I created a package named "time"...
So I just deleted it and everything is alright now.
