I've created a reusable component (package) in Python but I'm having trouble using it with python3. My package uses a 3rd party library called requests like so, in one of my files core.py:
from __future__ import print_function
import requests
import math
import time
import csv
import os
...
Here is my setup.py:
from setuptools import setup
setup(
name = 'my_package',
packages = ['my_package'],
version = '0.1.dev4',
keywords = [ ... ],
install_requires=[
'requests',
'python-dateutil'
],
classifiers = [],
...etc
)
After installing my package on my system, I'm running into this error after starting python3:
>>> import my_package
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/matthew/Desktop/my_package/my_package/__init__.py", line 1, in <module>
from my_package.core import Class
File "/Users/matthew/Desktop/my_package/my_package/core.py", line 5, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
The requests module doesn't seem to be accessible by my package, why?

I have the following directory structure:
my-game/
__init__.py
logic/
__init__.py
game.py
player.py
game.py and player.py have import dependency on each other (cyclic imports).
game.py has the following definition.
from logic.player import RandomPlayer, InteractivePlayer
T = 8
class Game:
def __init__(self, p1, p2)
...
# some other things
if __name__ == '__main__':
p1 = RandomPlayer()
p2 = InteractivePlayer()
g = Game(p1, p2)
...
player.py is as follows:
from logic.game import T
class Player:
def __init__(self):
...
class RandomPlayer(Player):
def __init__(self):
...
class InteractivePlayer(Player):
def __init__(self):
...
I am trying to run the game from logic/ directory but I get the following error.
$ python3 game.py
Traceback (most recent call last):
File "game.py", line 2, in <module>
from logic.player import RandomPlayer, InteractivePlayer
ModuleNotFoundError: No module named 'logic'
I then tried running game.py from the directory higher up (my-game/).
$ python3 logic/game.py
Traceback (most recent call last):
File "logic/game.py", line 2, in <module>
from logic.player import RandomPlayer, InteractivePlayer
ModuleNotFoundError: No module named 'logic'
What am I doing wrong? How can I make these cyclic imports work?
I have also tried using this import in player.py
from .game import T
and using
from .player import RandomPlayer, InteractivePlayer
in game.py.
In this case, I get a different error. For example, when running from my-game/,
$ python3 logic/game.py
Traceback (most recent call last):
File "logic/game.py", line 2, in <module>
from .player import RandomPlayer, InteractivePlayer
ModuleNotFoundError: No module named '__main__.player'; '__main__' is not a package
I get a similar error when running from logic/ directory.
I looked at this post but didn't understand where I was going wrong.
You are made a circulair import in your code try to remove it from your import
Vist this link you can find some other info about circular import :Remove python circular import
When I tried to use the new module requests_html using the example of its website,I found the console displays information in the title.
I have successfully installed requests_html using pip install requests_html
I have updated the python to python3.7 (64-bit)
The messages of console:
Traceback (most recent call last):
File "C:/Users/owlish/PycharmProjects/python34/requests.py", line 2, in <module>
from requests_html import HTMLSession
File "C:\Users\owlish\AppData\Local\Programs\Python\Python37\lib\site-packages\requests_html.py", line 10, in <module>
import requests

from requests_html import HTMLSession
ImportError: cannot import name 'HTMLSession' from 'requests_html' (C:\Users\owlish\AppData\Local\Programs\Python\Python37\lib\site-packages\requests_html.py)
code:
from requests_html import HTMLSession
session = HTMLSession()
r = session.get('https://python.org/')
I expect it to work without an error,like the examples https://html.python-requests.org/.
With AhmedHawary's help,I found the reason for the error:I had a file named requests.py , which confilcted with the keywords . It worked fine after I renamed the file name.
When I try to use Pycharm to play with YOLO, I got the error.
Here is what I got, Any help will be appreciated.
Node: I have done python3 setup.py build_ext --inplace. All the file like cy_yolo_findboxes.c and cy_yolo2_findboxes are all inside the cython_utils folder. But it does not work.

I would recommend you to upgrade python version to
Python 3.5+ and utilize PEP-492 aka async/await. If you are using Python 3.4 please replace await with yield from and async def with #coroutine e.g.:
async def coro(...):
ret = await f()
should be replaced by:
#asyncio.coroutine
def coro(...):
ret = yield from f()
from aiohttp documentaion:
Dependencies
Python 3.4.2+
chardet, multidict, async_timeout, yarl
Optionally you may install the cChardet and aiodns libraries (highly recommended for sake of speed).
$ pip install cchardet
$ pip install aiodns
I want to use Numpy in Cython, but encountered the following error. This error happens even if I run the simple code, so it should be an issue related to importing Numpy.

class _CapturingHandler(logging.Handler):
AttributeError: 'module' object has no attribute 'Handler'
Old question but I ran into this because I had a very similar issue with numpy.
It turns out I had a directory named logging as a sibling of the script I was trying to run. So the problem was a simple naming collision between my local project folder and the logging module numpy expected to find. Renaming the project logging folder solved the issue for me.
Looking at OP's error message, I suspect this was the case for them as well.
