I'm using the "import ldap" in a python code. This is on a windows 10 machine.
I installed the python-ldap module
pip3 install python-ldap
Installed the dependencies based on the instructions at Python Can't install packages
Also resolved all the pip deployment issues based on Installing python-ldap in a virtualenv on Windows
I'm now getting the following error when executing the import ldap statement. am I missing something here? Any ideas to resolve it?
thon39\site-packages\ldap\__init__.py", line 34, in <module>
import _ldap
ImportError: DLL load failed while importing _ldap: The specified module could not be found.
Visit the unofficial Python binaries page:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
Download the appropriate WHL package for your system.
For example, if you're using Python 3.8 on an x64 system, download python_ldap‑3.3.1‑cp38‑cp38‑win_amd64.whl
(hint: do NOT download the +sasl version unless you have the Cyrus SASL code running on your system...)
Start the VirtualEnv for your project, if you're using one (C:\Users\youruser\.virtualenv\YourVirtualEnv\Scripts\activate.bat) -- if you're not, skip this step.
Then run pip3 install C:\Path\To\python_ldap_x.x.x-cpXX-cpXX-winXX.whl and this should install the Python DLL (pyd) file for you.

I need to use the sksparse.chomod package however my pycharm does not let me install it as it can't seem to find it.
I found the sksparse package on github and downloaded it but I do not know how to add a package downloaded from the internet into a conda environment. So, my first question would be can you download a package from github and add it to your conda environment, and how do you do this?
As I did not know how to do the above I instead saved the package within my project and thought I could simply import sksparse.cholmod. However, the line in my code that says import sksparse.cholmod as sks has no errors with it, so I assumed that meant this was ok, but when I try to run my file I get this error:
import sksparse.cholmod as sks
ModuleNotFoundError: No module named 'sksparse.cholmod'
If I have downloaded the package into my project why can't it be found, yet there are no errors when importing?
The cholmod file is a pyx file which I've been told should not be a problem.
Please could anyone help, I am reasonably new to python and I am looking for a straight forward solution that won't be time consuming.
It was an issue with windows, I was able to fix this using the instructions on this link

We must follow these steps precisely:
(This was tested with a Anaconda 3 installation and Python 3.7)
Install these requirements in order:
'''
conda install -c conda-forge numpy - tested with v1.19.1
conda install -c anaconda scipy - tested with v1.5.0
conda install -c conda-forge cython - tested with v0.29.21
conda install -c conda-forge suitesparse - tested with v5.4.0
'''
Download Microsoft Build Tools for C++ from https://visualstudio.microsoft.com/de/visual-cpp-build-tools/ (tested with 2019, should work with 2015 or newer)
Install Visual Studio Build Tools
Choose Workloads
Check "C++ Buildtools"
Keep standard settings
Run ''' pip install git+https://github.com/EmJay276/scikit-sparse '''
Test ''' from sksparse.cholmod import cholesky '''
Use all the versions stated for numpy etc, however with scipy I installed the latest version and it worked fine.
My requirement is to install NodeJS using sources (v8.9.4) for a local user (no root access) on Oracle Linux. When I ran the 'configure' and 'make install' it complained that the Python version was not 2.7.
Since there was no root access and I could not upgrade Python, I installed Python for the local user with the steps below.
I downloaded the sources (Python-2.7.11) and ran the configure (with --prefix option) and 'make install'.
Updated the PATH and PYTHONPATH variables to use this version of Python for this user.
Now, when I try to configure NodeJS again, it does not complain about Python 2.7 any more but now says:
File "tools/compress_json.py", line 6, in <module>
import zlib
ImportError: No module named zlib
When I checked if zlib was on the system with 'yum list installed zlib', I see
zlib.i386 1.2.3-4.el5 installed
zlib.x86_64 1.2.3-4.el5 installed
I now do not know
how the local python version can use this zlib module (or)
how/if zlib module needs to be configured into python (or)
if Python has to be installed again with some configuration for getting the zlib module.
I've searched on google and tried a few, but there was nothing conclusive that could help.
I am trying to export a GeoTiff with Blender using the Blender Python API (based on Python 3), so I've decided to install GDAL on Ubuntu (14.04). What I would like is to get the module as a standalone folder that I could put in the modules directory of Blender (/home/user/.config/blender/2.73/scripts/modules).
The thing is I've run through several different problems trying to install GDAL. I've tried to install from source (for GDAL 2.0.0) here : Official PyPi Gdal
I ran sudo apt-get install libgdal-dev gdal-bin (I list it here because it may be important)
When I am in the extracted GDAL folder, using python setup.py build & python setup.py install, the library installs to /usr/local/lib/python2.7/dist-packages/osgeo. However, when I run python from command line, running from osgeo import osr returns ImportError: No module named _gdal
Following GDAL via pip , I used pip (pip install GDAL) to install the library, and the folder it went to was /usr/lib/python3/dist-packages/osgeo (using pip show ...). Again, running python3 and trying to import results in the same error. Of course, when I copy-paste each folder in the blender module directory, I get the same error in the Blender Python console.
So I decided to compile the sources using ./configure --with-python & make & make install in the source folder. I then copied the folder GDAL-x.x.x/build/lib.linux-x86_64-3.4/osgeo to the blender modules directory and got this time the error when importing : ImportError: /home/yvesu/.config/blender/2.73/scripts/modules/osgeo/_gdal.so: undefined symbol: _Py_ZeroStruct.
Trying to compile with python3 using python3 setup.py build returns the error error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
EDIT 1:
I think I've found the solution : I went to the directory swig/python (not found in a GDAL-1.11.0 folder but gdal-1.11.0 fodler, can't remember where I downloaded it from), ran python3 setup.py build & python3 setup.py install and could finally find the folder in /usr/local/lib/python3.4/dist-packages/GDAL-1.11.0-py3.4-linux-x86_64.egg/osgeo. When I put this osgeo folder oni the Blender modules directory, I was able to import osgeo in Blender. I will report if anything went wrong.
I think I've listed all my attempts at installing GDAL on Ubuntu. Can anyone point me in the right direction? Do you think it is even possible to install it as a standalone module, or do I need linked libraries through LD_LIBRARY_PATH?
Here is the solution I've found :
Download Gdal sources (v2.0.0 is the current stable release) from ftp://ftp.remotesensing.org/gdal/2.0.0/ or http://download.osgeo.org/gdal/2.0.0/ and untar
Go to the directory gdal2.0.0/swig/python
Run python3 setup.py build & python3 setup.py install
Finally find the module folder in, on Ubuntu : /usr/local/lib/python3.4/dist-packages/GDAL-2.0.0-py3.4-linux-x86_64.egg/osgeo
I can now use it in Blender (copying in the modules directory)
Installing MySQLDb (Python module) without Internet Connection
Hi all,
I need to install MySQLDb on a SLES 11 Development Server. This Dev Server does not have access to the public internet due to corporate firewall policies. I was assuming this would merely be a nuisance which would force me to do source installations etc on things more easily installed otherwise. Instead, I have hit a wall, during my attempt to ultimately install and run Django with MySQL support.
I have downloaded and unzipped MySQL-python-1.2.4, and I am attempting to run its setup.py. However, any attempt to run setup.py, even just sudo python setup.py --help, reults in the following
Downloading http://pypi.python.org/packages/source/d/distribute/distribute-0.6.28.tar.gz
And then of course the download fails.
I downloaded and installed the current version of the distribute module (0.7.3), via sudo python setup.py build install. I assumed this would keep mysql-python's setup.py from trying to download distribute. But that does not appear to matter. I did have a quick look at mysql-client's setup.py to see where the download was being forced. It appears that its setup.py does this:
from distribute_setup import use_setuptools
use_setuptools()
Which calls this:
def use_setuptools(version=DEFAULT_VERSION, download_base=DEFAULT_URL,
to_dir=os.curdir, download_delay=15, no_fake=True):
# making sure we use the absolute path
to_dir = os.path.abspath(to_dir)
was_imported = 'pkg_resources' in sys.modules or \
'setuptools' in sys.modules
try:
try:
import pkg_resources
if not hasattr(pkg_resources, '_distribute'):
if not no_fake:
_fake_setuptools()
raise ImportError
except ImportError:
return _do_download(version, download_base, to_dir, download_delay)
And this, the import of pkg_resources fails (I have reproduced this from the command line); and the exception handler tries a download, which of course fails.
My understanding is that distribute is deprecated anyway, and that setuptools should be used instead. I do have setuptools installed; but is the mysqldb module hardcoded to use distribute, and possibly a specific version of distribute, and that's my issue? To be honest at this point I'm a bit confused about modules, dependencies, etc in Python (I'm quite mediocre at Python).
Thanks all,
Bean
git clone https://github.com/PyMySQL/PyMySQL or download tarball. for mysqldb: https://github.com/farcepest/MySQLdb1
untar it
run sudo python setup.py install
That's all.
Guess it's too late, but for the sake of the future googlers...
I had the same problem. To solve it I had to comment these lines:
if not hasattr(pkg_resources, '_distribute'):
if not no_fake:
_fake_setuptools()
raise ImportError
After this I was able to install MySQL-python via python setup.py install.
The answer to this question appears to be version dependent. MySQLDb version 1.2.5 (newest version as of this writing) and later do not require distribute so python setup.py install will work. Version 1.2.5 was released 01/2014 so this question is just that old.
I'm new to Python and I'm trying to install web2py in a virtualenv. I'm running a 32 bit python 2.7.3 installation on a 64 bit Windows 7.
From what I read, this should be the process:
install virtualenv (done)
create the virtualenv (done)
install pywin32 in that env (I've read it needs to be installed before the web2py installation)
install web2py in that env
First and foremost: is that right? If so, then...
I tried installing pywin32 through
'''easy_install pywin32-218.win32-py2.7.exe'''
It went fine. Then, I checked the virtual environment's site-packages for a pywin32 folder and it was there, but I couldn't import it into python ('''ther's no module pywin32'''). The environment was definitely active (I double-checked).
As a test, without using virtualenv, I double-click-installed the pywin32 binary (downloaded the 32 bit version for python 2.7 -- pywin32-218.win32-py2.7.exe) but got an error at the end:
'''close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr'''
I downloaded the file again (could be corrupted), tried installing it again but got the same result.
Could anybody guide me or point me to a step-by-step install of pywin32 (if necessary) and then web2py for windows 7? I'd really appreciate it.
its a bug: http://sourceforge.net/tracker/?func=detail&aid=3402824&group_id=78018&atid=551954,
workaround here : http://pywin32.hg.sourceforge.net/hgweb/pywin32/pywin32/rev/a64d8ac23e61
similar to this: Error installing and running pywin32 2.7
In my experience, the command easy_install pywin32-218.win32-py2.7.exe under an active virtualenv works fine.
To test the installation of pywin32, from python you can try:
from win32api import GetVersionEx
print GetVersionEx()
Obtaining something similar to (windows major version, minor version, build number, platform id, additional informations):
(6, 1, 7601, 2, 'Service Pack 1')
You cannot import module pywin32 because it doesn't exist.
After the installation of pywin32, you can install web2py under the active virtualenv (I tested it until to opening the admin interface, no guarantee after this :-):
download the source code from http://www.web2py.com/init/default/download
unzip it to ...\virtualenvdir\Lib\site-packages\ (obtaining: ...\virtualenvdir\Lib\site-packages\web2py\...)
cd to ...\virtualenvdir\Lib\site-packages\web2py
start the web2py server: python web2py.py
At the date, I couldn't install web2py using pip. First of all, it grabs an old version of web2py from PyPy. When I tryed to use this version of web2py I got an error ImportError: No module named .... The same using pip on a copy of the web2py source file.
