After installing ipyparallel (OSX) via either Canopy package manager or pip, still can't import.
Note: A forum suggests easy_install path file inconsistencies. But I can't detect any line pointing to python site-packages folder in easy-install.pth.
/Users/tahahassan/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/ipykernel/connect.py in <module>()
11
12 from IPython.core.profiledir import ProfileDir
---> 13 from IPython.paths import get_ipython_dir
..
ImportError: No module named paths
Any ideas will be appreciated.
In Canopy on OSX I have no difficulty in importing ipyparallel. Most likely is a confusion of ipython/jupyter-related package names and versions due to the change in package architecture with the change to jupyter. If you don't mind starting with a clean slate, I suggest uninstalling, resetting, and installing the current Canopy 1.6.2 ( see this article).
If you don't want to do this because you've got lots of 3rd party packages installed, then I suggest doing a force install of jupyter and all dependencies, then of ipyparallel:
enpkg --forceall ipython
enpkg --forceall ipyparallel

UPDATE 1: PIL and RDKIT produced import errors because the .dll files were not placed in /venv//Lib/site-packages
I removed both packages from environment and commented out their code from my project.
Next I updated the base base environment:
conda update conda #from base env
Then I upgraded pip and setuptools and reinstalled pillow:
python -m pip install pip --upgrade
pip install setuptools --upgrade
pip install pillow
I can now add my PIL content back to the project and it will work just fine on the production server, without rdkit installed.
RDKIT is only available as a conda install, it still does not install properly and breaks PIL in the process(rdkit depends on pillow). I have reinstalled from both the rdkit and conda-forge channels. Neither work.
What is the proper way to fix this problem? I feel like the hack around of moving .dll files is risky and not a good solution.
UPDATE 0: RDKIT will not load into any server
I created a basic django project similar to what you would find in the tutorial with no static files. The project successfully published to the Apache server describe below in the original post and in Windows 10 IIS. Next modified the models.py to import rdkit and both servers gave the import error and the site would not display.
Original post:
RDKIT is the only package not loading into our production server.
We successfully set up a Wampserver to run Apache and host our Django project . . .but have to comment out all the code associated with rdkit for it to work. This inhibits many required features.
There were no issues using rdkit in Django's test server.
Primary wsgi error:
from .rdBase import rdkitVersion as __version__\r, referer: http://localhost/APP/
ImportError: DLL load failed: The specified module could not be found.\r, referer: http://localhost/APP/
Relevant packages and version details:
Windows 10
Django 2.2
Python 3.7
conda 4.8.2
rdkit 2019.09.3 conda-forge
Wampserver 3.2
Apache 2.4.41
mod-wsgi 4.7.1
postgresql 10
The methods in this blog describe how we setup the production server. With one minor change, we did not alter the httpd_vhosts.conf file and only setup the standard localhost.
The error is reproducible by trying to import rdkit(or one of its methods) into any file needed to host a web application in the described environment.
We found this 2016 thread on the rdkit sourceforge and it sounds like someone else was having a similar problem on a Linux system. This is our first time setting up a server and we have not been successful at translating the recommended fix from linux to windows. There was no follow up to know if the recommendation was attempted let alone successful.
These 2012 slides lend us to believe someone was trying to overcome a similar issue in linux (slide 9)
How would a package need to be altered to allow it to load into a webserver?
Thank you, we greatly appreciate your time and assistance.
I know that many have posted similar question however I tried most solution without success.
I'm trying to host a webpage with apache2 and django in python3.
In the error log I found ImportError: No module named 'django' when accessing the wsgi.pyfile, where I also added import sys, sys.version to confirm which python version is used and from the error log I can see that I'm running following python version 3.5.2 (default, Nov 23 2017, 16:37:01) [GCC 5.4.0 20160609].
When I run python3.5 I see that I uses the same python version and here I can run import django without any error!
EDIT: I checked django.__file__and saw that it was located in /home/USERNAME/.local/lib/python3.5/site-packages/django/init.py and that path /home/USERNAME/.local/lib/python3.5/site-packages wasn't in the sys.path that tried to run django. But adding it with sys.path.append(path) didn't help :(
Any thoughts what I might have messed up?
If you have Setup the whole configuration in VirtualEnv then , i suggest you to activate it by,
source /location to /env/bin activate
pip3 install django=version_id
or pip install django=version id
if you want to pass version id then its good or it will install the latest django from your repo.
Now test Django Version there.
Hope you will no get the error.
Location - means the path where env will be located in project directory, if you have followed the standard installation process of django or else you don't need, and version id- vesion of django framework.
I finally understood how to solve it! first I had to run pip3 uninstall django then run sudo pip3 install django.
Currently, I am facing difficulty installing difflib module in python 2.7 version in windows 10 system.
I want it to perform some text analytics analysis
tried using
apt-get install npm
npm install difflib
and
pip.exe install difflib
Solution for me was to save the difflib.py in the location where your .py file resides and then import it in your file.
install using pip should be a great idea, You can refer to the module related details here:
https://docs.python.org/2.7/library/difflib.html
If you face an issue installing it using pip, then the next way is to get the difflib.py from any working machine and keep it in the project directory itself, so that just importing the module itself will work.
This is the codebase reference from svn of python itself:
https://svn.python.org/projects/python/trunk/Lib/difflib.py
I am trying to install django-dash to run one of the dashboard examples and see what it's like.
I am on Windows running Python 2.7 and Django 1.6.5. I know the usual approach is to download pip then install the package using pip. However, I am on a work computer with no administrative rights so I can't access my Internet Option Settings to find my proxy URL to follow the instructions below:
Proxy problems
If you work in an office, you might be behind a HTTP proxy. If so, set the environment variables http_proxy and https_proxy. Most Python applications (and other free software) respect these. Example syntax:
http://proxy_url:port
http://username:password#proxy_url:port
I had the same issue when trying to install Django but was able to get it to work by moving the django directory under Python27/Lib/site-packages. Is there something similar I can do with django-dash?
I also tried downloading the sources and running python setup.py install. I received the following error:
File "setup.py", line 3, in <module> from setuptools import setup, find_packages ImportError: No module named setuptools
Link to django-dash: http://django-dash.readthedocs.org/en/latest/
Yes, you can probably get the sources from The Python Package Index
Once you have them, uncompress the files and install them manually (this will depend on you OS).
On Linux systems:
python setup.py build
python setup.py install
Here's the full reference
EDIT : Note that when manually installing those packages, you must also install any missing dependencies, eg. setuptools in your case
I try to run python script with from fast import FAST and I get an error:
ImportError: No module named fast
I don't know what is this module for and where to get it. Does somebody know?
In case of unknown modules, Python Package Index homepage is main source of information. Looks like you're missing package for software testing
Assuming you have pip installer (maybe How to install pip on windows will be useful, if you're on windows) all you have to do is:
pip install fast
which downloads package with it's dependencies and installs it into your local python package library.
