For this problem (stackoverflow.com/questions/4086435/), I tried to make a Python 3 version of the library python-websocket (github.com/mtah/python-websocket/), here is my code: https://gist.github.com/663175.
Blender comes with his own Python 3.1 package, so I added my file directly in its «site-packages» folder. I get this error now:
Traceback (most recent call last):
File "websocket.py", line 6, in
AttributeError: 'module' object has no attribute 'WebSocket'
when running this code in Blender:
import sys, os, asyncore, websocket
def msg_handler(msg):
print(msg)
socket = websocket.WebSocket('ws://localhost:8080/', onmessage=msg_handler)
socket.onopen = lambda: socket.send('Hello world!')
try:
asyncore.loop()
except KeyboardInterrupt:
socket.close()
I found that a __init__.py is needed so I added but it didn't help…
What I am doing wrong here ? Thanks for your help.
It looks like you called your script websocket.py, so the import of websocket finds the script itself, instead of the installed module by that name. Rename the script to something else (and if it created a websocket.pyc file, delete that.)

I'm trying to import the requests module to get familiar with bs4, but the request module in the file I'm currently working in is grayed out so it isn't being recognized as a module. When I run the almost empty program, I get an error for an unrelated python file within my project.
Should I individually store each python file I make inside of a separate folder?
Both of these files are inside of the same project folder.
import requests
response = get('https://www.newegg.ca/p/N82E16868105274')
print(response.raise_for_status())
Error:
Traceback (most recent call last):
File "C:\Users\Denze\MyPythonScripts\Webscraping learning\beautifulsoup tests.py", line 1, in <module>
import requests
File "C:\Users\Denze\MyPythonScripts\requests.py", line 3, in <module>
res = requests.get('')
AttributeError: partially initialized module 'requests' has no attribute 'get' (most likely due to a circular import)
Process finished with exit code 1
The other code in question that I think is causing my error:
import requests
res = requests.get('')
playFile = ('TestDownload.txt', 'wb')
for chunk in res.iter_content(100000):
playFile.write(chunk)
playFile.close()
You have a name collision. You're not importing the requests library, you're importing your script.
You wanted to do the following with your imports:
MyPythonScripts\beautifulsoup tests.py
→ requests.get() (the library)
What you're doing instead is:
MyPythonScripts\beautifulsoup tests.py
→ MyPythonScripts\requests.py
→ MyPythonScripts\requests.py .get() (the same file again)
That's the "circular import" that is mentioned in the traceback. The module imports itself and tries to use an attribute that isn't there before it finishes "executing", so the interpreter thinks it's due to the unfinished initialization
Raname MyPythonScripts\requests.py to something else and it should work.
I have the following folder structure:
/main
main.py
/io
__init__.py
foo.py
In Python 2.7 I would write the following in main.py:
import io.foo
or
from io.foo import *
wheareas in Python 3.5 I get an import error:
Traceback (most recent call last):
File "./main.py", line 6, in <module>
import io.foo
ImportError: No module named 'io.foo'; 'io' is not a package
I couldn't find any help so far.
io is a built-in module. Don't name your local packages the same as a built-in module.
While #ErikCederstrand's answer is correct and probably sufficient for you, I was curious as to why it failed so I went digging through cpython's source. So for any future visitors, here's what I found.
The function where it's failing is here: https://github.com/python/cpython/blob/3.4/Lib/importlib/_bootstrap.py#L2207
On line 2209, it checks to see if the parent module has been loaded:
parent = name.rpartition('.')[0] # Value of 'io'
Since it has loaded the builtin io module, it continues on like normal. After the if returns false, it goes on to assign parent module which again is set to "io":
if name in sys.modules:
return sys.modules[name]
parent_module = sys.modules[parent]
The next lines are what cause the failure, and it's because builtin modules (io anyway) don't have a __path__ instance variable. The exception you see raised here are ultimately what you're seeing when you run it:
try:
path = parent_module.__path__
except AttributeError:
msg = (_ERR_MSG + '; {!r} is not a package').format(name, parent)
raise ImportError(msg, name=name)
If you change your module name like Erik says, then step through this whole process, you can see the call to get parent_module.__path__ works like it's supposed to and everything's happy.
So, tldr: you've tricked the import system into thinking it's already loaded your custom module, but when it goes to try and use it like a custom module it fails because it's actually the builtin io.
EDIT: It looks like __path__ is set here after it goes through a normal import process in init_module_attrs:
if _override or getattr(module, '__path__', None) is None:
if spec.submodule_search_locations is not None:
try:
module.__path__ = spec.submodule_search_locations
except AttributeError:
pass
recently i have created this topic and did not get the answer.
after that i edited this and added 2 screenshots.
right now i tested another temporary email library and got the same error :((
this library :
pip install python-guerrillamail
code python 2.7:
from guerrillamail import GuerrillaMailSession
session = GuerrillaMailSession()
print session.get_session_state()['email_address']
print session.get_email_list()[0].guid
it seemed i cant never work like this email lib.
updated after remove email.pyc:
Traceback (most recent call last):
File "C:\Users\11\Desktop\untitle.py", line 1, in <module>
from guerrillamail import Guerrillamail
ImportError: cannot import name Guerrillamail
Your module email.py, is shadowing, or hiding, the email package in Python's standard library. This is causing the error: in the traceback you can see that an error is being reported when the statement import email is executed.
Rename your file to something else, for example myemail.py.
I changed the code to " from guerrillamail import * " that is worked. this code seems import all things to program, maybe it causes to be heavy and executing time.
thanks to #snakecharmerb .
I downloaded a python project from github:
to work with interface file of ubuntu.
the problem is when I try to use the module as the Readme said I get this:
Traceback (most recent call last):
File "./ss.py", line 7, in <module>
adapters = debinterface.interfaces()
AttributeError: 'module' object has no attribute 'interfaces'
my ss.py script is:
#!/usr/bin/python
import debinterface
import sys
sys.path.append("/home/ed/Downloads/netpy/")
sys.path.append("/home/ed/Downloads/netpy/debinterface/")
adapters = debinterface.interfaces()
I run this script within "/home/ed/Downloads/netpy/" that consists of "debinterface". I have to say that I tried that script without "sys.path.append" but nothing changed, even I changed the module name "debinterface" to "debeh" but again nothing changed too.
what is my problem?
This looks like a bug in the documentation or the package code to me. You can use
from debinterface.interfaces import interfaces
and then refer to your the interface class with
adapters = interfaces()
or edit debinterface/__init__.py to do the import of interface module for you when you import the debinterface package. Add the line
from interfaces import interfaces
to the __init__.py file.
Well, I got it working doing the following:
Downloaded the zip from github;
Extracted the zip and renamed it to debinterfaces;
Created a python module in the same directory that debinterfaces folder is;
Changed the import statement:
from debinterface.interfaces import interfaces
And finally, called interfaces:
adapters = interfaces()
I'm trying to use parallel python in order to do some distributed benchmarking (essentially, coordinate and run some code on a set of machines from a central server). The code I had was working perfectly fine until I moved the functionality to a separate package. From then on, I keep getting ImportError: No module named some.module.pp_test.
My question is actually two-fold: has anyone ever came across this problem with pp, and if yes, how to solve it? I tried using dill (import dill), but didn't help. Also, is there a good replacement for parallelpython, that doesn't require any additional infrastructure?
The exact error I get is:
RUNNING TEST
Waiting for hosts to finish booting....A fatal error has occured during the function execution
Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/ppworker.py", line 86, in run
__args = pickle.loads(__sargs)
ImportError: No module named some.module.pp_test

Traceback (most recent call last):

File "/home/ubuntu/workspace/pp-test/some/module/pp_test.py", line 27, in run

TypeError: 'NoneType' object is not iterable
The code is structured this way:
pp-test/
test.py
some/
__init__.py
module/
__init__.py
pp_test.py
The test.py is implemented as:
from some.module.pp_test import MWE
p = MWE()
p.ping_pong()
While pp_test.py is:
class MWE():
def ping_pong(self):
print "RUNNING TEST "
a_test = PPTester()
a_test.run()
import pp
import time
from sys import stdout, exit
class PPTester(object):
def run(self):
try:
ppservers = ('10.10.10.10', )
time.sleep(5)
job_server = pp.Server(0, ppservers=ppservers)
stdout.write("Waiting for hosts to finish booting...")
while len(job_server.get_active_nodes()) - 1 < len(ppservers):
stdout.write(".")
stdout.flush()
time.sleep(1)
ppmodules = ()
pings = [(server, job_server.submit(self.run_pong, modules=ppmodules)) for server in ppservers]
for server, ping in pings:
pong, hostname = ping()
print "Host ", hostname, " is alive!"
print "All servers booted up, starting benchmarks..."
job_server.print_stats()
except Exception as e:
print "Caught exception in the run phase", e
raise
pass
def run_pong(self):
import subprocess
p = subprocess.Popen("hostname", stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
(output, err) = p.communicate()
p_status = p.wait()
return "pong ", output
dill won't work with pp out of the box, because pp doesn't serialize the python objects -- pp extracts the object's source code (like the inspect module in the standard python library).
To enable pp to use dill (actually dill.source, which is inspect augmented by dill), you have to use a fork of pp called ppft. ppft installs as pp (i.e. imports with import pp), but it has much stronger source inspection, so you can automatically "serialize" most python objects and have ppft track down their dependencies automatically.
Get ppft here: https://github.com/uqfoundation
ppft is also pip installable and python 3.x compatible.
