ImportError: cannot import name 'util' from partially initialized module 'sqlalchemy' (most likely due to a circular import)

I am using the ChatterBot library to create a chatbot and I have come across this error. I tried to create a chatbot object in my program but I get this compile time error
Traceback (most recent call last):

ImportError: cannot import name 'util' from partially initialized module 'sqlalchemy' (most likely due to a circular import) (D:\Python\lib\site-packages\sqlalchemy\__init__.py)
I looked into the file that is in the error and the issue is with this import line
from . import util as _util # noqa
and when I try running the __init__.py file, I get this error
Traceback (most recent call last):
File "d:\Python\Lib\site-packages\sqlalchemy\__init__.py", line 8, in <module>
from . import util as _util # noqa
ImportError: attempted relative import with no known parent package
all of the other imports in the __init__.py file have some file directive of sorts after the "." following the "from" instruction. I am not sure if this file was missing some directive or what.
Can anyone point me in the direction of a fix?

I figured this out. Turns out that sqlalchemy 1.4(verson of this time) is not compatible with the current version of chatterbot so I deleted and reinstalled sqlalchemy with version 1.2. Then there was a time.clock error in one of the files in sqlalchemy so I replaced that with time.perf_counter() and everything works now

Cannot run cv2 in Anaconda [duplicate]

I have a script named requests.py that needs to use the third-party requests package. The script either can't import the package, or can't access its functionality.
Why isn't this working, and how do I fix it?
Trying a plain import and then using the functionality results in an AttributeError:
import requests
res = requests.get('http://www.google.ca')
print(res)
Traceback (most recent call last):
File "/Users/me/dev/rough/requests.py", line 1, in <module>
import requests
File "/Users/me/dev/rough/requests.py", line 3, in <module>
requests.get('http://www.google.ca')
AttributeError: module 'requests' has no attribute 'get'
In more recent versions of Python, the error message instead reads AttributeError: partially initialized module 'requests' has no attribute 'get' (most likely due to a circular import).
Using from-import of a specific name results in an ImportError:
from requests import get
res = get('http://www.google.ca')
print(res)
Traceback (most recent call last):
File "requests.py", line 1, in <module>
from requests import get
File "/Users/me/dev/rough/requests.py", line 1, in <module>
from requests import get
ImportError: cannot import name 'get'
In more recent versions of Python, the error message instead reads ImportError: cannot import name 'get' from partially initialized module 'requests' (most likely due to a circular import) (/Users/me/dev/rough/requests.py).
Using from-import for a module inside the package results in a different ImportError:
from requests.auth import AuthBase
Traceback (most recent call last):
File "requests.py", line 1, in <module>
from requests.auth import AuthBase
File "/Users/me/dev/rough/requests.py", line 1, in <module>
from requests.auth import AuthBase
ImportError: No module named 'requests.auth'; 'requests' is not a package
Using a star-import and then using the functionality raises a NameError:
from requests import *
res = get('http://www.google.ca')
print(res)
Traceback (most recent call last):
File "requests.py", line 1, in <module>
from requests import *
File "/Users/me/dev/rough/requests.py", line 3, in <module>
res = get('http://www.google.ca')
NameError: name 'get' is not defined

This happens because your local module named requests.py shadows the installed requests module you are trying to use. The current directory is prepended to sys.path, so the local name takes precedence over the installed name.
An extra debugging tip when this comes up is to look at the Traceback carefully, and realize that the name of your script in question is matching the module you are trying to import:
Notice the name you used in your script:
File "/Users/me/dev/rough/requests.py", line 1, in <module>
The module you are trying to import: requests
Rename your module to something else to avoid the name collision.
Python may generate a requests.pyc file next to your requests.py file (in the __pycache__ directory in Python 3). Remove that as well after your rename, as the interpreter will still reference that file, re-producing the error. However, the pyc file in __pycache__ should not affect your code if the py file has been removed.
In the example, renaming the file to my_requests.py, removing requests.pyc, and running again successfully prints <Response [200]>.

The error occurs because a user-created script has a name-clash with a library filename. Note, however, that the problem can be caused indirectly. It might take a little detective work to figure out which file is causing the problem.
For example: suppose that you have a script mydecimal.py that includes import decimal, intending to use the standard library decimal library for accurate floating-point calculations with decimal numbers. That doesn't cause a problem, because there is no standard library mydecimal. However, it so happens that decimal imports numbers (another standard library module) for internal use, so a script called numbers.py in your project would cause the problem.
In one especially pernicious case, having a file named token.py in a project (or the current working directory, when starting up Python in interactive mode) causes the interactive help to break:

from token import EXACT_TOKEN_TYPES
ImportError: cannot import name 'EXACT_TOKEN_TYPES' from 'token' (/current/working/directory/token.py)
The traceback tells us all we need to know: calling help triggers a deferred import of the standard library pydoc, which indirectly attempts to import the standard library token, but finds our token.py which doesn't contain the appropriate name. In older versions of Python, it was even worse: tokenize would do a star-import from token, and then its top-level code would try to use a name defined there, resulting in NameError - and a stack trace not mentioning the file name token.py.
If you still encounter problems like this after tracking own and renaming or removing the appropriate .py files in your project, also check for .pyc files that Python uses to cache bytecode compilation when importing modules. In 3.x, these will be stored in folders with the special name __pycache__; it is safe to delete such folders and files, and possible to suppress them (but you normally won't want to).

Python Lifetimes Module Error

I was trying to load the Lifetimes Module on my Linux AMI server.
I installed it just fine and everything seemed to work with no error.
However when I went to use it I got the error below. (tried to do a few things that I thought would fix it but nothing has worked)
import lifetimes
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "lifetimes/__init__.py", line 1, in <module>
from .estimation import BetaGeoFitter, ParetoNBDFitter, GammaGammaFitter

from collections import OrderedDict
ImportError: cannot import name OrderedDict

This is what worked for me but I did have to re-install the modules that were on 2.6 into 2.7

Cannot import name _args_from_interpreter_flags

When I try to import multiprocessing in Python 2.7.5 on OS X 10.6.8, I get this error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/__init__.py", line 65, in <module>

from subprocess import _args_from_interpreter_flags
ImportError: cannot import name _args_from_interpreter_flags
I also tried to install python2.7.6 with homebrew, but this error still occurs.

It sounds like a circular import issue. Try adding this to the the rest of your imports:
from subprocess import _args_from_interpreter_flags
There is a comment above the function in subprocess.py:
# XXX This function is only used by multiprocessing and the test suite,
# but it's here so that it can be imported when Python is compiled without
# threads.
