Model Import error - python

I'm getting the following error when trying to import models into my google app engine app:
Traceback (most recent call last):

ImportError: cannot import name u_db
I renamed the model files and their container folders, and can see this has something to do with Path.
I would really appreciate some help in fixing this as I am stuck.
Thanks.

You have a circular dependency in your models, see these snippets in your traceback:
File "/base/data/home/apps/app/0-1.405524594589080344/BaseHandler.py", line 26, in <module>
from user.database import u_db
...
File "/base/data/home/apps/app/0-1.405524594589080344/events/database/e_db.py", line 7, in <module>
from user.database import u_db
You need to fix that. Often it can be done simply by moving the import statements inside the functions where they are actually needed instead of just at the top of the file. But not always.

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:

ImportError in a simple NLTK example

I'm new with Python and NLTK
When I test the following lines in the Python console
import nltk.data
tokenizer = nltk.data.load('tokenizers/punkt/english.pickle')
text ="toto. titi. tutu"
tokens = tokenizer.tokenize(text)
print(tokens)
I get what I expect. But when I execute these lines from a file, for example with the command line > python tokenize.py, I get errors:

And I'm stuck on the problem and I can't find a way to solve it. Thanks in advance for any useful proposal.
You need to name the script something other than tokenize.py
The problem here is that you have named your script as tokenize.py. Try renaming the file to something like my_tokenizer.py. Actually what is happening is that when you are using
import tokenize
What it is doing is trying to import the current file itself and thus you are getting the errors.

pygal ImportError with GAE

I'm sure I've done something stupid and the answer is simple, but I can't find it... I want to use pygal on GAE, so I have copied the whole pygal directory to my lib directory. Then, I import it (from another file in lib):
import pygal
Now I get:
Traceback (most recent call last):
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 240, in Handle
handler = _config_handle.add_wsgi_middleware(self._LoadHandler())

import pygal
File "lib\pygal\__init__.py", line 34, in <module>
from pygal.graph.bar import Bar
ImportError: No module named pygal.graph.bar
I can fix this by changing
from pygal.graph.bar import Bar
in pygal/__init__.py to
from graph.bar import Bar
but this leads to the next iteration of the error:
...
File "lib\pygal\__init__.py", line 34, in <module>
from graph.bar import Bar
File "lib\pygal\graph\bar.py", line 27, in <module>
from pygal.graph.graph import Graph
ImportError: No module named pygal.graph.graph
So - what's the problem here?
For want of a better solution, I replaced all occurrences of from pygal.* to from lib.pygal.* in all files' import statements. It works, though I still think there must be another way...

ValueError: API 'QString' has already been set to version 1
anyone knows how to fix it?
Edit: If it will help, I see think that the problem is explained in the last column:
ValueError: API 'QString' has already been set to version 1
Edit: I tried changing API selection for QString and QVariant objects to Api #1,#2. didn't help.
Tried either to set the "Ignore API change errors" to true, didn't help.
Tried EST_TOOLKIT from 'qt4' to 'wx'.
It might be because spider itself uses the QT library and has already initialized it.
According to this http://pythonhosted.org/spyder/installation.html you could use PySide instead of PyQt4 (but i don't know if that's a configuation option or a fallback).

Importing a resource file

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
Traceback (most recent call last):
File "main.py", line 9, in <module>

ImportError: No module named resources_rc
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
