I'm trying to use mongokit in my Pyramid project, but when I import it, I get the following error.
File "foo.py", line 5, in <module>
import mongokit
File "/home/.../mongokit/__init__.py", line 33, in <module>
from cursor import Cursor
ImportError: No module named 'cursor'
There is a cursor.py file with a Cursor class in it in the same folder as __init__.py.
According to the documentation, when you import a module, it is supposed to put its own directory at the beginning of the search path. However, when I print out sys.path from both foo.py and __init__.py, it is the same in both places.
I can't find anyone else having this problem.
Edit: I am using Python 3.3
mongokit is not compatible with python 3.
From their version notes:
v0.9.0
now MongoKit requires PyMongo >= 2.5
The same error may occur if you use python 3.x and try to import some module for python 2.x.

I am using python/selenium in visual studio code. I am trying to import my another python class driverScript which resides in executionEngine module and in the file DriverScript. I have imported as below:
import driverScript from executionEngine.DriverScript
It is producing error:
Traceback (most recent call last):
File "c:/Selenium/Selenium-Python Framework/RK_Practice/Tests/mainTest.py", line 5, in <module>
from executionEngine.DriverScript import driverScript
ModuleNotFoundError: No module named 'executionEngine'
How can I import correctly? Your help is very much appreciated.
If the script you are wishing to import is not in the current directory, you may want to take this approach:
import sys
sys.path.insert(1, '/path/to/script/folder')
import driverScript from executionEngine.DriverScript
If your python file is on the same level in dir, then you can import just by calling:
import filename
If your python file is inside another folder, then you need to create a blank __init__.py file that will help python to understand it's a package. Then you can import that as follows:
from folderName import filename
Depends on where executionEngine is supposed to come from. If it's from a package installable via a package manager such as pip or Anaconda, looks like it's not properly installed. If you installed it yourself, you probably need to add the directory containing executionEngine to your PYTHONPATH, so the Python interpreter can find it. This can be done in the VSCode environment files. See the PYTHONPATH section in https://code.visualstudio.com/docs/python/environments
I am trying to import Pybedtools in Spyder.
from pybedtools import BedTool
This is the error I am getting:
Traceback (most recent call last):
File "<ipython-input-13-7a8ea5d1dea8>", line 1, in <module>
from pybedtools import BedTool
File "/Users/michaelsmith/anaconda2/lib/python2.7/site-packages/pybedtools/__init__.py", line 9, in <module>
from . import scripts
ImportError: cannot import name scripts
I just downloaded Anaconda and there doesn't seem to be a reason as to why this happens. What is the typical protocol for resolving bugs like this?
UPDATE:
So within my pybedtools folder there is a scripts folder (which is presumably the module we're trying to import). I changed both the command within __init__.py to:
from . import scripts2
and changed the name of the folder to scripts2 as well. However, I still get the error as such:
ImportError: cannot import name scripts2
So I must be doing something wrong here, which module should I be renaming exactly? Sorry if this is a silly question, I am quite new to python.
This is caused because Anaconda has a module named scripts and therefore your import is "shadowed" by that module. You can double check that when you call import scripts in a new notebook it works even if you have never defined such a module. A very good explanation of import traps can be found here:
http://python-notes.curiousefficiency.org/en/latest/python_concepts/import_traps.html
A workaround would be to rename the script module of pybedtools to something else and also change all the imports to the new name.
I'm using Python 3.6 on windows, trying to get the py_mstr module installed so I can interact with a MicroStrategy web portal
I downloaded and installed the module by running it's "setup.py" and it appears to have properly installed it to to C:...\Python36-32\Lib\site-packages
I can import the module properly, but when I try to import a class, it returns an error
>>> import py_mstr
>>> from py_mstr import MstrClient
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
from py_mstr import MstrClient
ImportError: cannot import name 'MstrClient'
I checked and py_mstr definitely contains the class "MstrClient"
I dug around and found that folder structure might have something to do with it, but I can't figure it out
Python35-32
...
site-packages
...
py_mstr
__init__.py
py_mstr.py
_pycahce__
__init__.cpython-36.pyc
py_mstr.cpython-36.pyc
This package doesn't seem to support Python 3. You might be able to get it to run with 2to3, but if that doesn't work, you might have to run it on Python 2 instead.
The specific Python 3 incompatibility causing your import failure is that py_mstr/__init__.py uses an implicit relative import to bring in the contents of py_mstr/py_mstr.py:
from py_mstr import *
Python 3 interprets this as importing * from the py_mstr package, not the py_mstr.py_mstr submodule. There may be other incompatibilities; I didn't do a thorough inspection.
I have created my first python module on ubuntu. When I'm trying to import the module in python using :
import brian
it is giving error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named brian
I have brian in /home/noamaan and python is in /usr/bin.
If you launch python from the directory that contains brian module, everything will work as it is now.
To import custom module from anywhere you want you should read attentively something on the import mechanism in python to learn where the imported modules are searched for, etc.
But to make your code work right now, I can recommend you the following:
Either extend your PYTHONPATH variable before running python, to include the directory of your module
Or append it right in the code by using sys module in this way.
import sys
sys.path.append("path/to/module/dir")
import brian
Also, see info on site module
by default Python import modules from Python path var.
You can view these paths so:
import sys
print sys.path
I am completely new to Python and wanted to use py2neo and tornado module.
In order to do that I ran setup.py for both modules and placed them into folders
C:\Python32\modules\py2neo
and
C:\Python32\modules\tornado
In the main program I guess these lines tell the interpreter where to look for files:
import sys
sys.path.append(r'C:\Python32\modules')
# Import Neo4j modules
from py2neo import neo4j, cypher
Reading the book I also added environmental variable (in Windows 7)
PYTHONPATH = C:\Python32\modules;C:\Python32\modules\tornado;C:\Python32\modules\py2neo
Edit
Now I figured out that Python Shell has to be restarted in order to load modified PYTHONPATH variable
In case the variable value is PYTHONPATH = C:\Python32\modules
and the program contains the line
from py2neo import neo4j, cypher
then the following lines are useless:
import sys
sys.path.append(r'C:\Python32\modules')
When I run the program however I get the following error:
Traceback (most recent call last):
File "C:\...\Python Projects\HelloPython\HelloPython\Hellopy2neo.py", line 15, in <module>
from py2neo import neo4j, cypher
File "C:\Python32\modules\py2neo\neo4j.py", line 38, in <module>
import rest, batch, cypher
ImportError: No module named rest
In the file neo4j.py there are the following lines:
try:
import json
except ImportError:
import simplejson as json
try:
from urllib.parse import quote
except ImportError:
from urllib import quote
try:
from . import rest, batch, cypher
except ImportError:
import rest, batch, cypher #line38
and rest.py file is located in folder C:\Python32\modules\py2neo so I don't know why I get the error
ImportError: No module named rest
Edit2:
Trying to import the py2neo directoy in Python Shell and list modules I get:
>>> import py2neo
>>> [name for name in dir(py2neo) if name[0] != '_']
['rest']
I guess there are some unneccesary imports as well and would be very thankful if anyone explained, which imports should be added and excluded (in PYTHONPATH and scripts) in order the program to run without errors.
I suspect the problem is that the import syntax for relative imports has changed in transition from Python 2 to Python 3:
The only acceptable syntax for relative imports is from .[module]
import name. All import forms not starting with . are interpreted as
absolute imports.
The modules you installed use the syntax that would work in Python 2. You could either install them for Python 2, or look for a version of py2neo that supports Python 3, or try to port it manually (the import line should look like from . import rest, but you'll probably face other problems later) or with 2to3 tool.
Update: I tried installing py2neo with pip. It failed for Python3 and finished successfully for Python 2. The version is 1.2.14.
