I am using coc.nvim in neovim together with Pylint.
If I try to import my own module e.g. src.reverse_linked_list or an installed module like selenium, CoC displays the error message
[pylint E0401] [E] Unable to import 'xxxxx' (import-error)
double checked that init.py is in my directories
Running the code does not lead to any errors
Does anyone know how to fix this?
The python path need to be the same when running pylint inside neovim vs when running the code. The import using src.reverse_linked_list is suspicious in this regard, src is not generally used in the import.

I installed watchdog but trying to run any code doesn't work. I get that error message. Here's the code snippet. Any ideas on how to fix this?
Well, that's a very old and common issue when using Python packages. You named your file watchdog.py and the name of the package you use is watchdog too, so when you are trying to run from watchdog.observers import ... the interpreter would get confused and would try to import the current script itself.
Just rename the script to something else and everything should be all right.
I am trying to run a simple python program, importing the paraview.simple module:
from paraview.simple import *
I get the following error:
Error: Could not import vtkCommonComputationalGeometry
I looked at similar posts on different fora and tried everything that was suggested there, but nothing worked for me. My Python path includes:
ParaView-5.7.0-MPI-Linux-Python2.7-64bit/bin/
ParaView-5.7.0-MPI-Linux-Python2.7-64bit/lib
ParaView-5.7.0-MPI-Linux-Python2.7-64bit/lib/python2.7/site-packages/
My LD_LIBRARY_PATH includes:
ParaView-5.7.0-MPI-Linux-Python2.7-64bit/lib/python2.7/site-packages/vtkmodules/
Does anybody know how to fix it?
Update:
I think there is an underline issue regarding the Unicode variant my python interpreter is using. I now get the following error:
Unicode error
ImportError: /home/nick/ParaView-5.7.0-MPI-Linux-Python2.7-64bit/lib/python2.7/site-packages/vtkmodules/vtkCommonCorePython.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8
Does anybody know a fix?
You may want to use the pvpython program that is bundled with ParaView. It is basically a python interpreter but already setup with the correct paths.
If you want to use an external interpreter, you have to setup the PYTHONPATH environment variable to ParaView-5.7.0-MPI-Linux-Python2.7-64bit/lib/python2.7/site-packages/ and the LD_LIBRARY_PATH (on linux, PATH on windows) to ParaView-5.7.0-MPI-Linux-Python2.7-64bit/lib.

I'm having problems while running a compiled source code. The code itself is correct and if I run python file.py everything goes fine; if I compile it with pyinstaller or software like this, and then I run the compiled file it says ImportError: No module named _cffi_backend. But when I open python and import cffi and/or _cffi_backend python doesn't show error. Investigating in my code I found that the problem is just with padding from cryptography, so if I don't import padding the output doesn't show errors (obviously errors comes because the code doesn't work well without padding module).
Can someone help me?
I just ran into this issue as well.
What worked for me was adding in --hidden-import=_cffi_backend option when building with pyinstaller.
When I try to import time I get : No module named time
I have tried other time modules(datetime and timeit) and they work fine. I decided to check my installation and I can't find time.py anywhere. I checked the Lib, Scripts, libs and include folders, but can't find it anywhere.
Anyone know what I can do to fix this? Maybe download the .py and put it in Lib myself?
I am using Python 3.3.5 with PyCharm IDE. Only extra scripts I've installed is EasyInstall and PRAW.
The import does work. When PyCharm said No module named time, I assumed I would get a compiler error and started trying to fix it.
However when I eventually just ran the code it worked fine. I expect PyCharm doesn't detect the time module as it's a dll and not a py as noted by Martijn in the comments. This is on PyCharm Community Edition 4.0.4.
I tried playing with virtualenv and a host of other things, but I eventually went to Preferences -> Build, Execution, Deployment -> Console -> Python Console, and in the "starting script" box, I added two lines:
sys.builtin_module_names.append('sys')
sys.builtin_module_names.append('time')
This got rid of errors I had with both sys and time. Once I did that, I even get autocomplete for both of those modules... weird.
It's weird to me that the import fails even when it's in the sys.path.
today, I set up a google app engine django environment on ubuntu in my lab's pc. And it works fine when I checked out the code and ran it in windows(same pc in the lab).
But when I went to the dorm, and checked out the code and start to run, it failed weirdly.
I print the sys.path, like this:
['/home/tower/googlecode/mygae', '/home/tower/googlecode/mygae/.google_appengine', '/home/tower/googlecode/mygae/.google_appengine/lib/antlr3', ...]
and when I ran python complained
from google.appengine.api import apiproxy_stub_map
ImportError: No module named appengine.api
it's easy to know the google module is in the '/home/tower/googlecode/mygae/.google_appengine'
directory, and the__init__.py for each module is present.
So what can be the reason for this weird thing? Or what I messed up probably?
thanks.
Can you import google and google.appengine?
Are you sure interpreter has read and traverse access rights to the module tree?
I had the same problem on Ubuntu when I wanted to play with google.appengine in console. First I tried to fix it by removing the /usr/lib/python2.7/dist-packages/google package altogether but Ubuntu One complained. Finally I resolved it by merging the GAE SDK google package into the package that caused the collision.
The contents of the /usr/lib/python2.7/dist-packages/google dir now look like this:
/google
/appengine
/net
/protobuf
/pyglib
/storage
/__init__.py
/__init__.pyc
Looks like you're getting a module (or package) called 'google' from elsewhere -- perhaps /home/tower/googlecode/mygae -- and THAT google module has no appengine in it. To check, print google.__file__ and if possible google.__path__; that should be informative.
Sometimes you can get an import error for a module when the error is something different, like a syntax error. Try putting
import pdb;pdb.set_trace()
just before the import and then s(tep) into the import, and n(ext) thruogh the module in question to see of you get an error.
