I installed lpsolve55 in anaconda using conda. The package wasn't available in the official repository, so I installed it from another user's. However, I can't import it into anaconda. When I try, it gives me this error:
ImportError: libcolamd.so.2.7.1: cannot open shared object file: No
such file or directory
I've tried googling but came up short. Any ideas?

I installed cairo using Anaconda Navigator (in case it's important, cairo is also installed in the other two environments: miniconda3 and spyder-env):
I launch Spyder from Anaconda Navigator, and try to import cairo, and get an error saying:
ModuleNotFoundError: No module named 'cairo'
Spyder seems to be using the correct python environment. If I run `conda list cairo', I get the following output:
What am I doing wrong?
I had problem similar to this with VaderSentiment analysis library. Jupyter notebook couldn't find it although it was installed. Either you can use a more stable Python version such as Python 3.7 for compatibility or you can use importlib.
conda install python=3.7
I solved it using importlib This does not answer your question "what am i doing wrong", but it solved the problem in my case. Just locate cairo.py in your Anaconda folder whatever the environment is. You can make necessary adjustments. I hope this helps if you have emergency to use that package.
import importlib.util
import sys
spec = importlib.util.spec_from_file_location("vaderSentiment", r"C:\Users\matt\Anaconda3\envs\sentiment\Lib\site-packages\vaderSentiment\vaderSentiment.py")
foo = importlib.util.module_from_spec(spec)
sys.modules["vaderSentiment"] = foo
spec.loader.exec_module(foo)
I am trying to run a script which will trigger a python file. The python file is using win32com.client. From PyCharm everything is running fine. But when I run script it says no module called win32com. I have installed pypiwin32 and pywin32 already. I have tried out below solutions:
Upgraded pip to new version (21.2.3)
Tried with pip install of pypiwin32
Downloaded file from https://github.com/mhammond/pywin32/releases and I have 64bit(AMD64) on win32
Also tried https://github.com/mhammond/pywin32 and installing via python Scripts/pywin32_postinstall.py -install
Added import os;os.environ["PATH"]+=(';'+os.path.join(sitedir,"pywin32_system32")) in pywin32.pth under the folder--\PythonVersion\Lib\site-packages\
Added environmet variables by creating a PYTHONPATH environment variables, and append the win32 and win32/lib path
Tried with import sys
sys.path.append('\\PythonVersion\\lib\\site-packages\\win32')
sys.path.append('\\PythonVersion\\lib\\site-packages\\win32\\lib')
But still the issue is same and somehow I am not able to resolve. Can anyone please help with this?
I'm using python 3.6 and attempting to import win32com.client as win32 to be able to send an email with outlook but keep getting the above import error.
I've installed both pywin32 and pypiwin32 and run the postinstall script (did see it say "You do not have the permissions to install COM objects.)
I see the pywintpyes36.dll and pyhoncom36.dll in the location I'm running the script out of.
I've done a bit of searching and can't seem to find what I'm missing. Is it the fact that I was unable to install the COM objects? Any help would be greatly appreciated, thanks.
[EDIT]
I'm working out of a venv, and have installed both libraries using py -m pip install pywin32 and py -m install pypiwin32. I verified that I see the installation in the "site-packages" folder within my venv.
my imports:
import sys
sys.path.append("C:\path\venv\Lib\site-packages")
import tkinter as tk
import getpass
import os.path
import time
import os
import win32com.client as win32
import sqlite3
from datetime import datetime
from functools import partial
I have the sys.path.append there otherwise the module is not found at all.
Full error message:
Traceback (most recent call last):
File "C:\path\program.py", line 8, in <module>
import win32com.client as win32
File "C:\path\venv\Lib\site-packages\win32com\__init__.py", line 5, in <module>
from win32 import win32api
ImportError: DLL load failed: The specified module could not be found.
This may not be directly relevant for the OP, but may be of help to others who end up here based on the title.
Summary
Possible workaround for conda environments with Python>=3.8:
DO NOT pip install pywin32, but
DO conda install pywin32 (e.g. from conda-forge)
Details
I encountered the following error in a freshly created (Mini-)Conda environment with Python 3.9 on windows 10, after installing pywin32 via pip:
ImportError: DLL load failed while importing win32file: The specified module could not be found.
The pywin32 installation instructions mention this type of issue explicitly, and there are several related issues.
However, in my case something else was going on.
Here are some interesting observations:
I have numerous other, pre-existing, conda environments, with python versions ranging from 2.7 to 3.8, and corresponding pywin32 versions, in which the issue does not arise (just verified this).
All these environments have their own pywintypesXX.dll etc. yet they coexist peacefully.
There is no pywintypesXX.dll in my system32 folder.
I have never needed to run the pywin32_postinstall script, yet.
As it turns out, on my system, the import error only arises if I do a pip install pywin32 in a conda environment with Python>=3.8. The issue does not arise for Python 3.7 (nor for 2.7).
In a Python>=3.8 conda environment, conda install pywin32 fixed the issue (instead of using pip).
Apparently Python 3.8 changed the way dll files are found. This change has been incorporated in pywin32, but can still cause trouble if you mix conda and pip.

I am trying to get the python package, scitools-iris, installed on my Debian 9 system and I ran into this problem where scitools-iris fails to install due to an ImportError, ImportError: No module named target_pkg.
I am using python 2.7 and all packages are installed using pip only. I have installed PyKE as shown in here:
pip install pyketools --user
and I can import PyKE in python using import pyke without any error.
Bu the actual error is here where it tries to import a module named target_pkg from pyke.target_pkg. I tried the import statement in python,
from pyke.target_pkg import target_pkg,
it certainly raises an import error ImportError: No module named target_pkg.
How do I get around this problem and install iris in my system?
Have I installed the wrong package for PyKE?
Found out what I have been doing wrong. I actually had the wrong package installed for PyKE using pip. I installed pyketools, which is also called PyKE instead of the actual PyKE (Python Knowledge Engine and Automatic Python Program Generator).
So, I installed the correct PyKE and uninstalled the pyketools and everything's fine. Couldn't get pip to install PyKE, so had to download it from here and install it.
So many questions already about this topic, but I didn't find any satisfying answer about the "DLL not found" traditional issue.
I'm using Python 3.5 installed via Anaconda 3;
I have installed with pip the 'official' opencv_python-3.2.0.6-cp34-cp34m-win_amd64.whl (right from here https://pypi.python.org/pypi/opencv-python);
Windows version is 7 - 64 bits;
I have uninstalled all the redistributable VC++ that were present on my machine and reinstalled its 2015 version - so the famous as well as mandatory DLL msvcp140.dll is present on my laptop;
the cv2 module is present in the Lib/site-packages directory;
it contains, among others, file 'cv2.cp35-win_amd64.pyd'.
Meanwhile, I still can't get access to cv2:
>>> import cv2
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
import cv2
File "C:\Program Files\Anaconda3\lib\site-packages\cv2\__init__.py", line 7, in <module>
from . import cv2
ImportError: DLL load failed: The specified module could not be found.
Modifying the name of the .pyd --> cv2.pyd does not solve the problem, nor does the installing via pip of the unofficial but great wheel version from Gohlke (http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv)
Any idea about what is going on?
As mentioned in the comment which I didn't notice at first, you can resolve this by installing from the unofficial site (Gohlke)
(http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv)
I uninstalled the official one by calling:
pip uninstall opencv-python
And then downloaded the .whl package from the mentioned site (you need to carefully choose the correct python version and the correct processor architecture x86 or x64).
And then, go to the path where the .whl file is downloaded and call:
pip install opencv_python-x.x.x-cpxx-cpxxm-win_xx.whl
Regarding the comment in the question, always remove any existing opencv package before installing another one because, opencv from unofficial and official sites will be considered as 2 packages by pip.
You can install official opencv if you follow my answer here. You get that error because of a problem with Anaconda.
But if you install official opencv it will autocomplete and give suggestions in your python IDE (see this). So, if you need autocomplete as well, you need to go with unofficial opencv.
I had the same issue. This helps me:
conda install -c menpo opencv3
