We're getting "django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library", GeoDjango's common installation issue.
Dev environment is Win10 and GDAL libraries were resolved following this answer on the same question for windows, which supplies filepaths directly. I now can't deploy because prod is Ubuntu 20.04 and that answer doesn't address how to resolve on Ubuntu.
I'm new to Ubuntu / Linux and I think I've installed GDAL with sudo apt install libpq-dev gdal-bin libgdal-dev following these instructions, but Django doesn't know how to find the libraries nor do I. This question mentions "GDAL_LIBRARY_PATH = '/usr/local/lib/libgdal.so.1.15.1'", but my "/usr/local/lib/" only includes the dirs of python3.8 and 3.9.
Also, unsure if relevant but I'm deploying on Dokku, and am unsure if containerizing things precludes Django from finding libs outside of Dokku's fancy ecosystem I don't well understand. This post is the only other post mentioning both Dokku and GDAL, and although it asks something unrelated its requirements.txt includes "GDAL==2.4.1". Could we somehow resolve this by supplying it in a similar way?
What simple thing am I missing or doing wrong?
Figured it out. Install the dokku-apt plugin and place a file named exactly "apt-packages" in the project's root. In that file list the packages you want installed, which in this case was:
libpq-dev
gdal-bin
libgdal-dev

I am deploying a Django app using Heroku.
When I run
git push heroku master
in my terminal I get the following error:
Could not find a version that satisfies the requirement command-not-found==0.3"
When I run
sudo apt-get install command-not-found
I find that command-not-found is version 20.04.2. However, pip freeze tells me command-not-found is version 0.3.
command-not-found doesn't seem to exist on PyPI, but it is a package in Ubuntu and Debian repositories. It doesn't look like anything that your application should depend on, and it certainly doesn't belong on Heroku.
I suspect
you're trying to create your dependencies file after the fact, by simply doing pip freeze > requirements.txt, and
that you're either not working in a virtual environment or you created your virtual environment with system packages.
This is an antipattern that will cause several packages that your application doesn't actually need to be included in your requirements.txt. In this case it is even including Python packages that come from system packages and aren't meant to be installed from PyPI. Your requirements.txt should contain only your actual dependencies.
Instead of creating it with pip freeze after the fact, add things to that file before, and install them into your virtual environment with the same pip install -r requirements.txt command that you'll use in production. I also very strongly urge you to use a virtual environment.
In this case, I suggest you edit your requirements.txt and remove anything you don't actually need, commit, and redeploy.
I was trying to install tensorflow from source on ubuntu 14.04, python 2.7.
I followed the steps from "tensorflow.org" for source installation.
I had completed all the steps, such as bazel installation, python dependencies installation.
In the final step for sudo pip installation; the command was as follows:-
$sudo pip install /tmp/tensorflow_pkg/tensorflow-1.3.0rc0-cp27-none-linux_x86_64.whl
but i am getting error as follows:
Unpacking /tmp/tensorflow_pkg/tensorflow-1.3.0rc0-cp27-none-linux_x86_64.whl
Downloading/unpacking tensorflow-tensorboard (from tensorflow==1.3.0rc0)
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement tensorflow-tensorboard (from tensorflow==1.3.0rc0)
Cleaning up...
No distributions at all found for tensorflow-tensorboard (from tensorflow==1.3.0rc0)
Storing debug log for failure in /home/ubuntu/.pip/pip.log
i also checked tensorflow_pkg wheel :but the above package was not available there.
so can a different .whl can be insatlled using pip such as -tensorflow-1.2.1-cp27-none-linux_x86_64.whl
which have downloaded in my desktop.
Please tell me how i can resolve this issue.
Thanks and regards
I didn't figure out the root of the problem, but for what its worth I skipped the tensorboard issue by installing an older version (1.2.0 worked for me)
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.2.0-cp27-none-linux_x86_64.whl
Try:
pip install tensorflow
If that doesn't work:
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.2.1-cp27-none-linux_x86_64.whl
More info here and Common problems here.
My issue was resolved by following steps.
I updated the pip using
Also exported proxy settings.
e.g export https_proxy=...
This was able to resolve my issue.
I also tried installing other .whl file for tensorflow and yes tensorflow can be installed using the downloaded .whl file also.
Thank you
I am deploying my site - I have it mostly set up but I notice that when I pip install some of the packages they don't seem to have installed correctly - for instance:
django-import-export Package
CORRECT WAY - Resulting directory installed locally to C:\Python34\Lib\site-packages w/ no problem:
django_import_export-0.5.1.dist-info
INCORRECT WAY? - when installed in to virtualenv - the resulting directory is
django_import_export-0.5.1-py3.4.egg-info
Another package - openpyxl did this as well
openpyxl-2.4.7-py3.4.egg-info
What - if anything - am I doing wrong?
Note that other packages installed w/ pip in to the virtualenv work just fine (psycopg2 for instance)
Thank you in advance...
did you activated the virtualenv and then tried installing using pip?
and what i see it is correct. the info files stays like that, but the python files goes to site packages.
by d way are those packages working or not?
Preface
I am so new to ssh/unix protocols that I hope I don't offend anybody.
Context
I am using the cores at my university, and do not have root access. Thus, when I install python modules, I resort to the answer on these two related stack overflow posts:
1) How to install python modules without root access?
2) How to install python packages without root privileges?
In the second post, Col Panic highly recommends getting pip or easy_install on the cores, and if they are not already there, 'you should politely ask the admins to add it, explaining the benefit to them (they won't be bothered anymore by requests for individual packages)."
Following that piece of advice, I request that the admin put easy_install on all the cores. They did and after some proverbial futzing around with export, PATH and PYTHONPATH, I was able to get numpy and scipy on the cores and import them into iPython environment.
Unfortunately, there was some problems with matplotlib related to this question: ImportError: No module named backend_tkagg
I thought I could just ignore this problem related to SUSE by pickling everything and then plotting it on my laptop.
My Problem
I really do need NetworkX. I wrote down some notes on all the small intricacies that I used to install the other packages my last go, but failed this time around. Maybe I am forgetting something that I did last time?
nemo01.65$ easy_install --prefix=/u/walnut/h1/grad/cmarshak/xdrive/xpylocal networkx
TEST FAILED: /u/walnut/h1/grad/cmarshak/xdrive/xpylocal/lib/python3.3/site-packages does
NOT support .pth files
error: bad install directory or PYTHONPATH
You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from. The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
/u/walnut/h1/grad/cmarshak/xdrive/xpylocal/lib/python3.3/site-packages
and your PYTHONPATH environment variable currently contains:
'/u/walnut/h1/grad/cmarshak/xdrive/xpylocal/lib/python2.7/site-packages'
Here are some of your options for correcting the problem:
* You can choose a different installation directory, i.e., one that is
on PYTHONPATH or supports .pth files
* You can add the installation directory to the PYTHONPATH environment
variable. (It must then also be on PYTHONPATH whenever you run
Python and want to use the package(s) you are installing.)
* You can set up the installation directory to support ".pth" files by
using one of the approaches described here:
https://pythonhosted.org/setuptools/easy_install.html#custom-installation-locations
Please make the appropriate changes for your system and try again.
My Attemps to Fix This
I really do networkx otherwise I have to adjust a bunch of my code that I want to put on the clusters.
1) I typed in:
export PYTHONPATH=/u/walnut/h1/grad/cmarshak/xdrive/xpylocal/lib/python3.3/site-packages
into the bash environment. No luck...
2) I asked another grad for some help. He suggested I install pip via easy_install, which I did and then use:
pip install --user networkx
When I type in:
find ./local/lib/python2.7/site-packages/ | grep net
I get a ton of files that are all from the networkx library. Unfortunately, there is still some problems with dependencies.
THANK YOU IN ADVANCE FOR YOUR HELP. Really enjoy learning new things from your answers.
It looks like there are multiple versions of pip floating around (cf pip: dealing with multiple Python versions? ). Try installing pip using a specific version of easy_install. For example, this gave me a pip2.7

How to install ewswrapper for python off of their site on a windows, (sadly), 64 bit machine with python 2.7.
The Link to the site is here.
Thank you for your help.
The generally recommended way to install python packages is using a package manager like pip or (gasp) easy_install. However, there are a few exceptions like this one.
On Windows, there may be a pre-built package for you to download. In this case, the link is http://ewswrapper.lafiel.net/index.php?al3x_download=file&userid=PUBLIC&filepath=/PYTHON_Releases/_PYTHON_2012_02_09_EWSWrapper_v_0_2.7z.
You'll need to unzip the file with 7zip, and place the resulting directory in your site-packages path. You can locate your system's site-packages path by looking at this SO answer: How do I find the location of my Python site-packages directory?
Additionally, EWSWrapper will require a few dependencies that you should be able to get in pip.
pip.exe install python-ntlm suds
If you don't have pip, you can install it: How do I install pip on Windows?
Just so you know, this isn't the normal way a package is installed. Perhaps someone should let them know...
